3. What is flu? flu is an acute viral infection of the respiratory tract (nose, mouth, throat, bronchial tubes and lungs) it is a highly infectious illness which spreads rapidly in closed communities even people with mild or no symptoms can infect others most cases in the UK occur during an 8 to 10 week period during the winter 3 The national flu immunisation programme 2014/15 The national flu immunisation programme 2016/17

4. Influenza viruses There are three types of influenza viruses: A viruses cause outbreaks most years and are the usual cause of epidemics live and multiply in wildfowl from where they can be transmitted to humans. Also carried by other mammals B viruses tend to cause less severe disease and smaller outbreaks burden of disease mostly in children predominantly found in humans C viruses minor respiratory illness only 4The national flu immunisation programme 2016/17

5. 5 Influenza Virus Single stranded RNA virus 3 types (A, B, C) Subtypes of A Haemaglutinin (H) antigen (H1-16) HA - for attachment of virus to receptors on cell membrane. Neuraminidase (N) antigen (N1-9) for viruses to be released from infected cell after replication - new viruses infect other cells and spread infection - major change (shift), A type - minor change (drift)

6. Genetic changes in the flu virus – what this means Changes in the surface antigens (H and N) result in the flu virus constantly changing antigenic drift: minor changes (natural mutations) in the genes of flu viruses that occur gradually over time antigenic shift: when two or more different strains combine. This abrupt major change results in a new subtype. Immunity from previous flu infections/vaccinations may not protect against the new subtype, potentially leading to a widespread epidemic or pandemic Because of the changing nature of flu viruses, WHO monitors their epidemiology throughout the world. Each year WHO makes recommendations about the strains of influenza A and B which are predicted to be circulating in the forthcoming winter. These strains are then included in the flu vaccine developed each year 6The national flu immunisation programme 2016/17

7. Flu vaccine effectiveness efficacy calculated at between 50-60% for adults aged 18 to 65 years lower efficacy in elderly although immunisation shown to reduce incidence of severe disease including bronchopneumonia, hospital admissions and mortality in 2014/15 the flu vaccine only provided limited protection against infection as the main A(H3N2) strain that circulated differed from the A(H3N2) strain selected for the vaccine however, throughout the last decade, there has generally been a good match between the strains of flu in the vaccine and those that subsequently circulated In 2015/16, the A(H1N1) strain was the predominant circulating virus for the majority of the season and was well matched to the vaccine strain. The UK provisional vaccine effectiveness was 52.4% (for all ages) and 57.6% for the live attenuated vaccine in children aged 2 to 17 years 7The national flu immunisation programme 2016/17

8. Features of flu easily transmitted by large droplets, small-particle aerosols and by hand to mouth/eye contamination from a contaminated surface or respiratory secretions of infected person people with mild or no symptoms can still infect others incubation period 1-5 days (average 2-3 days) though may be longer especially in people with immune deficiency Common symptoms include: sudden onset of fever, chills, headache, muscle and joint pain and extreme fatigue dry cough, sore throat and stuffy nose in young children gastrointestinal symptoms such as vomiting and diarrhoea may be seen 10The national flu immunisation programme 2016/17

9. Possible complications of flu Common: bronchitis otitis media (children), sinusitis secondary bacterial pneumonia Less common: meningitis, encephalitis, meningoencephalitis primary influenza pneumonia Risk of most serious illness is higher in children under six months, pregnant women, older people and those with underlying health conditions such as respiratory disease, cardiac disease, long-term neurological conditions or immunosuppression. Flu during pregnancy may be associated with perinatal mortality, prematurity, smaller neonatal size and lower birth weight 9The national flu immunisation programme 2016/17

14. UK flu vaccination programme late 1960s: annual flu immunisation recommended to directly protect those in clinical risk groups who are at a higher risk of influenza associated morbidity and mortality 2000: flu vaccine policy extended to include all people aged 65 years or over 2010: pregnancy added as a clinical risk category for routine flu immunisation 2013: phased introduction of an annual childhood flu vaccination programme for all children aged 2 to 16 years began with vaccine offered to all children aged 2 and 3 years and seven geographical pilots in primary school aged children 2014: phased introduction of childhood flu vaccination programme continued with vaccine offered to all children aged 2, 3 and 4 years and geographical pilots in primary and secondary school aged children 2015: offer to all 2, 3 and 4 year old children and children of school years 1 and 2 age 2016: offer to all 2, 3 and 4 year old children and children of school years 1, 2 and 3 age 14The national flu immunisation programme 2016/17

15. 2016/17 Influenza Season

16. Flu vaccine eligibility: 2016/17 flu season all children aged two, three and four years on 31 August 2016 all children of school years 1, 2 and 3 age all primary school-aged children in former primary school pilot areas those aged six months to under 65 years in clinical risk groups all pregnant women (including those who become pregnant during flu season) those aged 65 years and over (including those becoming 65 years by 31 March 2017 those living in long-stay residential care homes or other long-stay care facilities carers and household contacts of immunocompromised individuals Frontline health and social care workers should be provided flu vaccination by their employer. This includes general practice staff. 16The national flu immunisation programme 2016/17

17. Morbidly obese patients JCVI has advised morbidly obese patients (BMI 40+) could benefit from flu vaccination those with morbid obesity (BMI>40) found to be at higher risk of hospitalisation and death following pandemic influenza infection many in this patient group already eligible due to complications of obesity that place them in another risk category practices need to use clinical judgement to decide whether to vaccinate this group of patients however, flu vaccinations for morbidly obese patients with no other recognised risk factor will not attract a payment in 2016/17 17The national flu immunisation programme 2016/17

18. Clinical risk groups who should receive flu vaccine (1) Clinical risk categoryExamples (this list is not exhaustive and decisions should be based on clinical judgement) Chronic respiratory diseaseAsthma that requires continuous or repeated use of inhaled or systemic steroids or with previous exacerbations requiring hospital admission. Chronic obstructive pulmonary disease (COPD) including chronic bronchitis and emphysema; bronchiectasis, cystic fibrosis, interstitial lung fibrosis, pneumoconiosis and bronchopulmonary dysplasia (BPD). Children who have previously been admitted to hospital for lower respiratory tract disease. see precautions section on live attenuated influenza vaccine Chronic heart diseaseCongenital heart disease, hypertension with cardiac complications, chronic heart failure, individuals requiring regular medication and/or follow-up for ischaemic heart disease. Chronic kidney diseaseChronic kidney disease at stage 3, 4 or 5, chronic kidney failure, nephrotic syndrome, kidney transplantation. Chronic liver diseaseCirrhosis, biliary atresia, chronic hepatitis Chronic neurological disease (included in the DES directions for Wales) Stroke, transient ischaemic attack (TIA). Conditions in which respiratory function may be compromised due to neurological disease (eg polio syndrome sufferers). Clinicians should offer immunisation, based on individual assessment, to clinically vulnerable individuals including those with cerebral palsy, learning difficulties, multiple sclerosis and related or similar conditions; or hereditary and degenerative disease of the nervous system or muscles; or severe neurological disability DiabetesType 1 diabetes, type 2 diabetes requiring insulin or oral hypoglycaemic drugs, diet controlled diabetes. 18The national flu immunisation programme 2016/17

19. Clinical risk groups who should receive flu vaccine (2) Clinical risk categoryExamples (this list is not exhaustive and decisions should be based on clinical judgement) Immunosuppression (see contraindications and precautions section on live attenuated influenza vaccine) Immunosuppression due to disease or treatment, including patients undergoing chemotherapy leading to immunosuppression, bone marrow transplant, HIV infection at all stages, multiple myeloma or genetic disorders affecting the immune system (eg IRAK-4, NEMO, complement disorders) Individuals treated with or likely to be treated with systemic steroids for more than a month at a dose equivalent to prednisolone at 20mg or more per day (any age), or for children under 20kg, a dose of 1mg or more per kg per day. It is difficult to define at what level of immunosuppression a patient could be considered to be at a greater risk of the serious consequences of influenza and should be offered influenza vaccination. This decision is best made on an individual basis and left to the patient’s clinician. Some immunocompromised patients may have a suboptimal immunological response to the vaccine. Asplenia or dysfunction of the spleen This also includes conditions such as homozygous sickle cell disease and coeliac syndrome that may lead to splenic dysfunction. Pregnant womenPregnant women at any stage of pregnancy (first, second or third trimesters). (see precautions section on live attenuated influenza vaccine) 19The national flu immunisation programme 2016/17

20. Flu immunisation should also be offered to: those living in long-stay residential care homes or other long-stay care facilities where rapid spread is likely to follow introduction of infection and cause high morbidity and mortality (this does not include prisons, young offender institutions, university halls of residence etc) those who are in receipt of a carer’s allowance, or those who are the main carer of an elderly or disabled person whose welfare may be at risk if the carer falls ill household contacts of immunocompromised individuals, specifically those who expect to share living accommodation on most days over the winter and therefore for whom continuing close contact is unavoidable. health and social care staff in direct contact with patients/service users should be vaccinated as part of an employer’s occupational health obligation 20The national flu immunisation programme 2016/17

21. Other groups who should receive flu vaccine the list of clinical risk groups is not exhaustive healthcare practitioners should apply clinical judgement to take into account the risk of flu exacerbating any underlying disease as well as the risk of serious illness from flu itself flu vaccine should be offered to such patients even if the individual is not in the clinical risk groups specified in the risk groups list child contacts of very severely immunocompromised individuals should be given inactivated vaccine 21The national flu immunisation programme 2016/17

23. Vaccination of clinical risk groups increasing flu vaccine uptake in clinical risk groups important because of increased risk of death and serious illness if people in these groups catch flu for a number of years only around half of patients aged six months to under 65 in clinical risk groups have been vaccinated despite those with liver disease and chronic neurological disease having some of the highest mortality rates, they have low flu vaccine uptake rate compared with those in other clinical risk groups vaccine uptake for all those in clinical risk groups needs to improve, but particularly in those with chronic liver and neurological disease, and people with learning disabilities 23The national flu immunisation programme 2016/17

27. Pregnant women All pregnant women are recommended to receive the inactivated flu vaccine irrespective of their stage of pregnancy pregnant women at increased risk from complications if they contract flu having flu during pregnancy may be associated with premature birth and smaller birth size and weight flu vaccination during pregnancy provides passive immunity against flu to infants in the first few months of life studies on safety of flu vaccine in pregnancy show that inactivated flu vaccine can be safely and effectively administered during any trimester of pregnancy no study to date has demonstrated an increased risk of either maternal complications or adverse fetal outcomes associated with inactivated flu vaccine women should be offered the vaccine every time they are pregnant 27The national flu immunisation programme 2016/17

29. Why vaccinate children against flu? Extension of the seasonal flu vaccination programme to all children aims to appreciably lower the public health impact of flu by: providing direct protection thus preventing a large number of cases of flu infection in children providing indirect protection by lowering flu transmission from children: to other children to adults to those in the clinical risk groups of any age Reducing flu transmission in the community will avert many cases of severe flu and flu-related deaths in older adults and people with clinical risk factors. Annual administration of flu vaccine to children is expected to substantially reduce flu-related illness, GP consultations, hospital admissions and deaths. 29The national flu immunisation programme 2016/17

30. Health and social care workers frontline health and social care workers have a duty of care to protect their patients and service users from infection vaccination of health and social care workers protects them and reduces risk of spreading flu to their patients, service users, colleagues and family members evidence vaccination significantly lowers rates of flu-like illness, hospitalisation and mortality in vulnerable patients in long-term healthcare settings reduces transmission of flu to vulnerable patients, some of whom may have impaired immunity that may not respond well to immunisation vaccination of frontline workers also helps reduce sickness absences and contributes to keeping the NHS and care services running through winter pressures 30The national flu immunisation programme 2016/17

31. Health and social care workers (cont) NHS and social care bodies have a responsibility to ensure, as far as is reasonably practicable, that health and social care workers are free of, and are protected from exposure to infections that can be caught at work (Health and Social Care Act 2008, Code of Practice on the prevention and control of infections) responsibility for funding and administering seasonal flu vaccine to staff lies with employers trusts/employers must ensure that health and social care staff directly involved in delivering care are encouraged to be immunised and that processes are in place to facilitate this overall level of flu vaccine uptake in health care workers is still below the 75% aspiration see NHS Employers flu fighter campaign www.nhsemployers.org/flu 31The national flu immunisation programme 2016/17

32. Key messages to health and social care workers duty of care as professionals to patients or residents to do everything in your power to protect them against infection, including being immunised against flu getting vaccinated against flu can help protect you, your patients and family everyone is susceptible to flu, even if you are in good health and eat well you can be infected with the virus and have no symptoms but can still pass flu virus to others including patients or residents good infection control measures reduce spread of flu and other acute respiratory infections in healthcare settings but are not sufficient alone to prevent them impact of flu on frail and vulnerable patients can be fatal and outbreaks can cause severe disruption in communities, care homes and hospitals flu vaccine has a good safety record and will help protect you. It cannot give you flu. Having the vaccination can encourage your colleagues to do likewise throughout the last ten years there has generally been a good to moderate match between the strains of flu virus in the vaccine and those that subsequently circulated staff act as positive role models for patients aged 65 and over, those with long-term health conditions and pregnant women to take up the offer too 32The national flu immunisation programme 2016/17

33. When to vaccinate those eligible should be given flu vaccination as soon as vaccine is available so that people are protected when flu begins to circulate in the community ideally most vaccination should be completed before the end of December before flu circulation usually peaks flu can circulate considerably later than this however so clinical judgement should be applied to assess needs of individual patients and whether it is appropriate to continue to offer vaccination from January to March this decision should take into account level of flu-like illness in community and fact that the immune response following flu vaccination takes about two weeks to develop fully protection afforded by the vaccine thought to last at least one influenza season however, as antibody levels likely to reduce in subsequent seasons and may be changes to circulating strains from one season to next, annual revaccination is important 33The national flu immunisation programme 2016/17

34. 34 Which flu vaccine should be used? The national flu immunisation programme 2016/17

35. Trivalent vaccines will contain the following three viruses: an A/California/7/2009 (H1N1)pdm09-like virus an A/Hong Kong/4801/2014 (H3N2)-like virus a B/Brisbane/60/2008-like virus In addition to the above, the quadrivalent vaccine will also contain: B/Phuket/3073/2013-like virus None of the influenza vaccines for the 2016/17 season contain thiomersal as an added preservative. More detailed information on the characteristics of the available vaccines, including age indications can be found in the Influenza chapter of the Green Book (Immunisation against infectious disease) and the product SPCs. 35 Flu vaccine composition 2016/17 The national flu immunisation programme 2015/16

36. Types of flu vaccines Two main types of vaccine available: inactivated – by injection live attenuated – by nasal application None of the flu vaccines can cause clinical influenza in those that can be vaccinated  Trivalent: flu vaccines contain two subtypes of Influenza A and one type B virus  Quadrivalent vaccines contain two subtypes of Influenza A and both B virus types* As quadrivalent vaccines contain both lineages of B viruses and therefore may provide better protection against the circulating B strain(s) than trivalent flu vaccines, the live intranasal vaccine offered to children aged 2 years and over is a quadrivalent vaccine, as is the inactivated vaccine recommended for children aged 3 years and above who cannot receive live attenuated vaccine. *Quadrivalent inactivated flu vaccine only authorised for children aged 3 years and older. 36The national flu immunisation programme 2016/17

37. Inactivated flu vaccines a number of different manufacturers produce flu vaccines. Those available for 2016/17 season are listed in ‘The national flu immunisation programme 2016/17’ letter available on PHE website most of the inactivated vaccines are administered by intramuscular injection, although one vaccine (Intanza®) is administered by the intradermal route all currently available flu vaccines are prepared from viruses grown in embryonated hens’ eggs – details of ovalbumin content available in the product SPC some flu vaccines are restricted for use in particular age groups. The SPC for individual products should always be referred to when ordering vaccines for particular patients 37The national flu immunisation programme 2016/17

38. Live attenuated influenza vaccine (LAIV) a live attenuated intranasal spray is the recommended vaccine for the childhood flu programme the live attenuated influenza vaccine (LAIV) has been shown to be more effective in children compared with inactivated influenza vaccines it may offer some protection against strains not contained in the vaccine as well as to those that are and has the potential to offer better protection against virus strains that have undergone antigenic drift since this vaccine is comprised of weakened whole live virus, it replicates natural infection which induces better immune memory (thereby offering better long-term protection to children than from the inactivated vaccines) in addition to being attenuated (weakened), the live viruses in LAIV have been adapted to cold so that they cannot replicate efficiently at body temperature LAIV has a good safety profile in children aged two years and older 38The national flu immunisation programme 2016/17

39. Is LAIV effective? results from the 2013/14 child flu vaccine pilot programme suggest a positive impact on levels of flu in that flu season In pilot areas compared to non-pilot areas, there were fewer GP consultations and A&E attendances for ‘influenza like’ and respiratory illness and fewer people tested positive for flu in primary care in the 2014/15 flu season, vaccination of healthy primary school age children resulted in a population-level impact despite the circulation of drifted A and B influenza strains GP influenza-like consultations, A&E respiratory attendance, respiratory swab positivity, hospitalisation and excess respiratory mortality were consistently lower in both vaccinated and non-vaccinated individuals in the primary school age pilot areas for the 2015/16 flu season, the provisional end of season vaccine effectiveness for LAIV in children aged 2-17years was 57.6% 39The national childhood flu immunisation programme 2016/17

42. 42 Administration of flu vaccines The national flu immunisation programme 2016/17

43. Flu vaccine presentation and dosage 43 inactivated flu vaccines for intramuscular (IM) administration supplied as suspensions in pre-filled syringes containing a 0.5ml dose if SPC for IM inactivated flu vaccine states young children can be given either a 0.25ml or a 0.5ml dose, give 0.5ml dose Intanza®, the intradermal vaccine, is supplied in a micro-needle injection system the live intranasal flu vaccine is supplied as a nasal spray suspension in a special single use, pre-filled, nasal applicator. No reconstitution or dilution required. Each applicator contains 0.2ml (administered as 0.1 ml per nostril) The national flu immunisation programme 2016/17

44. Vaccine administration (inactivated vaccines) Intramuscular flu vaccines should be given into the upper arm (or anterolateral thigh in infants under one year of age). Individuals with a bleeding disorder should be given vaccine by deep subcutaneous injection to reduce the risk of bleeding Intradermal: Intanza® is supplied in a micro-needle injection system that should be held at right-angles to the skin. The device allows intradermal vaccination to be performed without the need for additional training both inactivated and live flu vaccines can be given at the same time as, or at any interval before or after, other live and inactivated vaccines different vaccines should be given at separate sites, preferably in a different limb. If given in the same limb, they should be given at least 2.5cm apart 44The national flu immunisation programme 2016/17

45. Administration of LAIV LAIV is different from other flu vaccines – it is a live attenuated nasal vaccine and must not be injected LAIV can be administered at the same time as, or at any interval from other vaccines including live vaccines patient should breathe normally – no need to actively inhale or sniff the vaccine is rapidly absorbed so no need to repeat either half of dose if patient sneezes, blows their nose or their nose drips following administration 45The national flu immunisation programme 2016/17

46. Flu vaccines for patients in clinical risk groups AgeWhich vaccine?How many doses? Children aged six months to less than two years of age in clinical risk groups These children should be offered inactivated trivalent influenza vaccine Those who have not received flu vaccine before should receive a second dose of vaccine at least four weeks later. Children aged two to less than 18 years of age in clinical risk groups These children should be offered the live intranasal vaccine unless it is medically contraindicated For those children for whom the live vaccine is medically contraindicated, a suitable inactivated flu vaccine should be offered. The quadrivalent inactivated influenza vaccine (Fluarix™ Tetra) is authorised for children from the age of three years and is preferred because of the additional protection offered. The quadrivalent vaccine has both lineages of influenza B and may therefore provide better protection against the circulating B strain(s) than trivalent inactivated influenza vaccines. Children aged two years should be given an inactivated trivalent vaccine. Those aged two to less than nine years who have not received flu vaccine before should receive a second dose of vaccine at least four weeks later Over 18 yearsAny of the inactivated vaccines (except Intanza®15μg which is for those age 60 years and over) A single dose 46The national flu immunisation programme 2016/17

47. Which vaccine and how many doses? Vaccine typeAuthorised age indicationDose Live attenuated intranasal vaccine Children aged two to under 18 years (if no contraindications) Single application in each nostril of 0.1ml Children NOT in clinical risk groups only require one dose of this vaccine. Children in clinical risk groups aged two to under nine years who have not received influenza vaccine before should receive a second dose of vaccine at least four weeks later. N.B Follow Green Book not SPC Inactivated intramuscular vaccine (number of different brands) Children aged six months and older and adults (N.B some of the vaccines are not authorised for young children) Single injection of 0.5ml Children aged six months to under nine years who have not received influenza vaccine before should receive a second dose of vaccine at least four weeks later. Inactivated intradermal vaccine - Intanza® 15µg Adults aged 60 years and olderSingle injection of 0.1ml 47The national flu immunisation programme 2016/17

48. 48 Which type of vaccine to offer children under 18 years old The national childhood flu immunisation programme 2016/17 Children in clinical risk groups aged two years to less than nine years who have not received flu vaccine before should be offered two doses of flu vaccine at least four weeks apart (LAIV or a suitable inactivated vaccine if LAIV is medically contraindicated).

49. Porcine gelatine the LAIV contains a highly purified form of gelatine derived from pigs gelatine is used to stabilise live viral vaccines and is commonly used in a range of pharmaceutical products, including many capsules and some vaccines some faith groups do not accept the use of porcine gelatine in medicinal products there is no other live attenuated vaccine available that does not contain porcine gelatine. The manufacturer of LAIV (Fluenz Tetra®) tested 40 potential stabilisers – gelatine was chosen because without it, stability was significantly reduced PHE and Department of Health’s view is that, for universal vaccination of healthy individuals, there is no suitable alternative to Fluenz Tetra®. The purpose of the childhood programme is to interrupt transmission and therefore indirectly protect whole population. This is best achieved by offering LAIV (Fluenz Tetra®) see www.gov.uk/government/news/vaccines-and-gelatine-phe-response for Q&As and more information on vaccines and gelatinewww.gov.uk/government/news/vaccines-and-gelatine-phe-response 49The national childhood flu immunisation programme 2016/17

50. 50 Storage and ordering The national flu immunisation programme 2016/17

51. Storage of flu vaccine Efficacy, safety and quality may be adversely affected if vaccines are not stored at the temperatures specified in the licence Flu vaccines must be stored in accordance with manufacturer’s instructions: store between +2 ⁰ C and +8 ⁰ C do not freeze store in original packaging protect from light Check expiry dates regularly: the LAIV has an expiry date 18 weeks after manufacture – this is much shorter than inactivated flu vaccines it is important that the expiry date on the nasal spray applicator is checked before use In the event of cold chain failure involving LAIV, refer to the document ‘Responding to cold chain failures involving the live attenuated intra-nasal influenza vaccine (LAIV)’ available on PHE Immunisation gov.uk website 51The national flu immunisation programme 2016/17

52. Vaccine ordering all flu vaccines for children (both live and inactivated) are purchased centrally by PHE. In 2016/17 this will be for: all children aged 2, 3 and 4yrs, and of school years 1, 2 and 3 age and all children in clinical risk groups aged 6 months to 18 years ie PHE will supply LAIV for those who can receive it and inactivated flu vaccine for those children for whom LAIV is contraindicated. the quadrivalent inactivated flu vaccine (Fluarix™ Tetra®) is authorised for children aged from three years and is preferred because of the additional protection offered. children aged from six months to less than three years should be given Inactivated Influenza Vaccine (Split Virion) BP® flu vaccines for children can be ordered through the ImmForm website as for other centrally purchased vaccines (www.immform.dh.gov.uk)www.immform.dh.gov.uk it is important not order or hold more than two weeks’ worth of LAIV – stockpiling increases the risk of significant loss if there are cold chain failures 52The national childhood flu immunisation programme 2016/17

53. 53 Supply and administration of flu vaccines A range of mechanisms can be used for the supply and administration of vaccines, including: patient specific prescription written manually or electronically by a registered medical practitioner or other authorised prescriber Patient Specific Direction (PSD) Patient Group Direction (PGD) PGD templates for the administration of the live and inactivated flu vaccines are available on the PHE website: https://www.gov.uk/government/collections/immunisation-patient-group-direction-pgd NB Local authorisation is required before PHE PGD templates can be used The national flu immunisation programme 2016/17

54. 54 Contraindications and precautions The national flu immunisation programme 2016/17

55. There are very few individuals who cannot receive any flu vaccine Where there is doubt, expert advice should be sought promptly so that the period the individual is left unvaccinated is minimised For children aged 2 up to their 18 th birthday, where live flu vaccine cannot be given, it is likely that inactivated vaccine could be given instead 55The national flu immunisation programme 2016/17 Contraindications

56. None of the influenza vaccines should be given to those who have had: confirmed anaphylactic reaction to a previous dose of the vaccine confirmed anaphylactic reaction to any component of the vaccine The live attenuated flu vaccine should not be given to children who are: clinically severely immunodeficient due to conditions or immunosuppressive therapy:  acute and chronic leukaemias  lymphoma  HIV infection not on highly active antiretroviral therapy  cellular immune deficiencies  high dose corticosteroids receiving salicylate therapy known to be pregnant The national flu immunisation programme 2014/15 Contraindications to flu vaccines 56The national flu immunisation programme 2016/17

57. Inactivated influenza vaccine for children contraindicated to receive LAIV children for whom LAIV is contraindicated should be offered a suitable alternative inactivated flu vaccine some inactivated flu vaccines have been associated with high rates of febrile convulsions in children some inactivated flu vaccines contain too much ovalbumin for egg allergic children check SPC for vaccine suitability before administration Guidance on which vaccines to use for those children who cannot receive LAIV can be found in the Green Book Influenza chapter Fluarix Tetra® is the preferred vaccine for children aged ≥ 3years who cannot receive Fluenz Tetra® children 6m to <3years should be given inactivated influenza vaccine (Split Virion) BP® 57The national flu immunisation programme 2016/17

58. Beware of product confusion! Fluarix® Tetra is an inactivated vaccine licensed from three years of age that can be given to children who cannot receive the live intranasal flu vaccine, the 65 and overs, the under 65s at risk, pregnant women and healthcare workers Care must be taken not to confuse the two ‘Tetra’ brands. One way of remembering which vaccine is which is: Fluenz is the nazal flu vaccine Fluarix is the arm injected vaccine 58The national flu immunisation programme 2016/17

59. Acutely unwell: defer until recovered Heavy nasal congestion: defer live intranasal vaccine until resolved or, if the child is in a risk group, consider inactivated flu vaccine to provide protection without delay Use with antiviral agents against flu: LAIV should not be administered at the same time or within 48 hours of cessation of treatment with flu antiviral agents administration of flu antiviral agents within two weeks of administration of LAIV may adversely affect the effectiveness of the vaccine 59The national flu immunisation programme 2016/17 Precautions to flu vaccines

60. Severe asthma or active wheezing live flu vaccine is not recommended for children and adolescents with severe asthma or active wheezing eg those who are currently taking or have been prescribed oral steroids for respiratory disease in the last 14 days children currently taking a high dose inhaled steroid - Budesonide >800mcg/day or equivalent (eg Fluticasone > 500mcg/day) should only be given live flu vaccine on the advice of their specialist As these children are a defined flu risk group, those who cannot receive LAIV should receive an inactivated flu vaccine vaccination with LAIV should be deferred in children with a history of active wheezing in the past 72 hours or those who have increased use of bronchodilators in the previous 72 hours. If condition not improved after a further 72 hours then inactivated flu vaccine should be offered to avoid delaying protection in this high-risk group 60Presentation title - edit in Header and Footer

61. Egg allergy – adults most flu vaccines are prepared from flu viruses grown in embryonated hens’ eggs – the final vaccine products contains varying amounts of egg (as ovalbumin) adults with egg allergy can be immunised in any setting using an inactivated flu vaccine with an ovalbumin content less than 0.12 µg/ml (equivalent to <0.06µg for 0.5ml dose) adults with severe anaphylaxis to egg that has previously required intensive care should be referred to specialists for immunisation in hospital there is no ovalbumin-free vaccine available for the 2016/17 flu season 61The national flu immunisation programme 2016/17

62. Egg allergy – children children with an egg allergy can be safely vaccinated with the LAIV in any setting (including primary care and schools) those with both egg allergy and clinical risk factors* that contraindicate LAIV (eg immunosuppression) should be offered an inactivated flu vaccine with a very low ovalbumin content (less than 0.12μg/ml) children with a history of severe anaphylaxis to egg that has previously required intensive care, should be referred to specialists for immunisation in hospital LAIV is not otherwise contraindicated in children with egg allergy. Egg- allergic children with asthma can receive LAIV if their asthma is well- controlled (see previous slide on severe asthma) *Children in a clinical risk group and aged under nine years who have not been previously vaccinated against influenza will require a second dose whether given LAIV or inactivated vaccine 62The national flu immunisation programme 2016/17

63. Flu vaccines with low or no ovalbumin content The following vaccines, available for the 2016/17 flu season, are egg-free or have a very low ovalbumin content (<0.12μg/ml – equivalent to <0.06μg for a 0.5ml dose) They may be used safely in individuals with egg allergy LAIV (Fluenz Tetra®), which has an upper ovalbumin limit of 1.2μg/ml, has also been shown to be safe for use in most egg allergic children A list of all flu vaccines for the 2016/17 season and their ovalbumin content is available in Vaccine Update June 2016 63The national flu immunisation programme 2016/17 SupplierName of productVaccine typeAge indication Ovalbumin content per dose ( μg/dose) GSKFluarix TetraSplit virion inactivated virusFrom three years ≤0.1 (≤0.05/0.5ml dose) MASTAInactivated Influenza Vaccine (Split Virion) BP Split virion inactivated virusFrom six months ≤0.1 (≤0.05/0.5ml dose) Sanofi Pasteur MSD Inactivated influenza vaccine (split virion) BP Split virion inactivated virusFrom six months ≤0.1 (≤0.05/0.5ml dose) Sanofi Pasteur MSD Intanza 15 micrograms Split virion inactivated virus60 years of age and over ≤0.24(≤0.024/0.1ml dose)

64. theoretical potential for transmission of live attenuated virus to immunocompromised contacts risk is for one to two weeks following vaccination extensive use of the live attenuated influenza vaccine in US – no reported instances of illness or infections from the vaccine virus among immunocompromised patients inadvertently exposed to vaccinated children however, where close contact with very severely immunocompromised patients (eg bone marrow transplant patients requiring isolation) is likely or unavoidable (eg household members) consider an appropriate inactivated flu vaccine instead 64The national flu immunisation programme 2016/17 Risk of transmission of live vaccine virus

65. Exposure of healthcare workers to live attenuated influenza vaccine viruses theoretically there may be some low level exposure to the vaccine viruses for those administering LAIV and/or from recently vaccinated patients in the US, where there has been extensive use of LAIV, no reported instances of illness or infections from the vaccine virus among healthcare workers inadvertently exposed risk of acquiring vaccine viruses from the environment is unknown but probably low the vaccine viruses are cold-adapted and attenuated and therefore unlikely to cause symptomatic influenza as a precaution, very severely immunosuppressed individuals should not administer LAIV other healthcare workers who have less severe immunosuppression or are pregnant, should follow normal clinical practice to avoid inhaling the vaccine and ensure that they themselves are appropriately vaccinated 65The national flu immunisation programme 2016/17

66. Inadvertent administration of LAIV if an immunocompromised individual receives LAIV, the degree of immunosuppression should be assessed if patient is severely immunocompromised, antiviral prophylaxis should be considered otherwise they should be advised to seek medical advice if they develop flu-like symptoms in the four days following administration of the vaccine if antivirals are used for prophylaxis or treatment, patient should also be offered inactivated flu vaccine in order to maximise their protection in the forthcoming flu season (this can be given straight away) 66The national flu immunisation programme 2016/17

67. Commonly reported adverse reactions Following inactivated flu vaccine: pain, swelling or redness at the injection site, low grade fever, malaise, shivering, fatigue, headache, myalgia and arthralgia a small painless nodule (induration) may also form at the injection site these symptoms usually disappear within one to two days without treatment Following live attenuated flu vaccine: nasal congestion/rhinorrhoea, reduced appetite, weakness and headache Rarely, after live or inactivated vaccine, immediate reactions such as urticaria, angio- oedema, bronchospasm and anaphylaxis can occur 67The national flu immunisation programme 2016/17

68. 68The national flu immunisation programme 2016/17 Reporting suspected adverse reactions All serious suspected reactions following flu vaccination should be reported to the Medicines and Healthcare products Regulatory Agency using the Yellow Card scheme at http://yellowcard.mhra.gov.uk/ http://yellowcard.mhra.gov.uk/ Fluenz Tetra® and Fluarix™ Tetra carry a black triangle symbol (▼) (as do all vaccines during the earlier stages of their introduction). This is to encourage reporting of all suspected adverse reactions

69. 69 Record keeping The national flu immunisation programme 2016/17

70. Recording of flu vaccine given As a wide variety of influenza vaccines are on the UK market each year, it is especially important that the following information be recorded: vaccine name, product name, batch number and expiry date dose administered date immunisation given route/site used name and signature of vaccinator This information should be recorded in: patient's GP record (or other patient record, depending on location) personal Child Health Record (the ‘Red Book’) if a child practice computer system Child Health Information System 70The national flu immunisation programme 2016/17

71. Data collection flu vaccine uptake data is collected via the web-based ImmForm system (www.immform.dh.gov.uk) where it is managed and published by PHEwww.immform.dh.gov.uk over 90% GP practices are able to make automated data returns where the number of their patients vaccinated is directly extracted from their IT system and put into ImmForm for data to be accurate and complete, it is critical that vaccines given outside the surgery, eg in antenatal clinics or pharmacies, are reported to the patient’s GP uptake data for school years 1, 2 and 3 and pilot areas will be manually submitted by providers onto ImmForm uptake data for HCWs is manually submitted by trusts and area teams via ImmForm data is collected and published monthly on all the groups for whom flu vaccine is indicated at national level and local NHS England team level to enable performance to be reviewed and time to take action if needed 71The national flu immunisation programme 2016/17

72. 72 Achieving high uptake The national flu immunisation programme 2016/17

73. Achieving high uptake (GP Practice checklist) In order to obtain high vaccine uptake, it is recommended that GP practices: 1.Identify a named lead individual within the practice who is responsible for the flu vaccination programme and liaises regularly with all staff involved in the programme 2.Hold a register that can identify all pregnant women and patients in the under 65 years at risk groups, those aged 65 years and over, and those aged two to four years 3. Update the patient register throughout the flu season, paying particular attention to the inclusion of women who become pregnant and patients who enter at-risk groups during the flu season 4. Submit accurate data on the number of its patients eligible to receive flu vaccine and the flu vaccinations given to its patients on ImmForm (www.immform.dh.gov.uk), ideally using the automated function, and submit data on uptake among healthcare workers in primary care using the ImmForm data collection tool 73The national flu immunisation programme 2016/17

74. Achieving high uptake (GP Practice checklist cont’d) 5. Order sufficient flu vaccine taking into account past and planned improved performance, expected demographic increase, and to ensure that everyone at risk is offered the flu vaccine. It is recommended that vaccine is ordered from more than one supplier and from PHE central supplies through the ImmForm website in respect of children 6. It is a requirement of the enhanced service specification that patients recommended to receive the flu vaccine are invited to a flu vaccination clinic or to make an appointment (eg by letter, email, phone call, text) 7. Follow-up patients, especially those in at risk groups, who do not respond or fail to attend scheduled clinics or appointments 8. Start flu vaccination as soon as practicable after receipt of the vaccine. This will help ensure the maximum number of patients are vaccinated as early as possible and protected before flu starts to circulate. Aim to complete immunisation of all eligible patients before flu starts to circulate and ideally by end of December 74The national flu immunisation programme 2016/17

75. Achieving high uptake (GP Practice checklist cont’d ) 9. Collaborate with maternity services to offer and provide flu vaccination to pregnant women and to identify, offer and provide to newly pregnant women as the flu season progresses 10.The GP practice should offer flu vaccination in clinics and opportunistically 11.The GP practice and/ or CCG should collaborate with other providers such as community pharmacies and community or health and social care trusts to identify and offer flu vaccination to residents in care homes, nursing homes and house- bound patients and to ensure that mechanisms are in place to update the patient record when flu vaccinations are given by other providers The GP practice checklist highlights good practice. it is based upon the findings from a study examining the factors associated with higher vaccine uptake in general practice GP practices are encouraged to review their systems in the light of the checklist most recommendations will apply to other settings where flu vaccine is given 75The national flu immunisation programme 2016/17

77. Key messages flu immunisation is one of the most effective interventions we can provide to reduce harm from flu and pressures on health and social care services during the winter it is important to increase flu vaccine uptake in clinical risk groups because of increased risk of death and serious illness if people in these groups catch flu for a number of years, only around half of patients aged six months to under 65 years in clinical risk groups have been vaccinated influenza during pregnancy may be associated with perinatal mortality, prematurity, smaller neonatal size, lower birth weight and increased risk of complications for mother vaccination of health and social care workers protects them and reduces risk of spreading flu to their patients, service users, colleagues and family members by preventing flu infection through vaccination, secondary bacterial infections such as pneumonia are prevented. This reduces the need for antibiotics and helps prevent antibiotic resistance 77The national flu immunisation programme 2016/17
