6 Impact of Vaccines During the 20th Century and Into the 21st Century DiseaseReported Cases (Year)Reported Cases (2009)% Decrease in Reported CasesDiphtheria5796 (1950)100%Tetanus486 (1950)1896%Pertussis120,718 (1950)16,85886%Measles319,124 (1950)7199%Mumps152,209 (1968)199199%Rubella46,975 (1966)3Hepatitis A*32,859 (1966)198794%Hepatitis B*26,611 (1985)340587%According to the Centers for Disease Control and Prevention, reported cases of many vaccine- preventable diseases (VPDs) decreased dramatically during the 20th century. This decrease in reported cases highlights one of the most important public health achievements of the last century—immunizations. As can be seen in this slide, the decrease in the number of reported cases of the VPDs shown ranges from 86% for pertussis to 100% for diphtheria. Vaccinations are, indeed, a major public health achievement.*Underreporting estimated at a factor of 4.3 for hepatitis A and 2.8 for hepatitis B thus actual number of cases likely substantially higher than reported numbers of cases.CDC.

7 Burden of Selected Vaccine-Preventable Diseases (VPDs) Influenza200,000 excess hospitalizations annually (>40% in the elderly)~24,000 excess deaths annually (~90% elderly)Invasive Pneumococcal Disease (IPD)~50,000 cases of bacteremia each yearHigher rates in elderly and persons with comorbiditiesCase fatality rates ~20% (up to 60% in the elderly)Hepatitis B78,000 new infections annually (highest in young adults)1 million with chronic hepatitis B virus infectionsComplications include cirrhosis and hepatocellular carcinoma (80% of cases)Human Papillomavirus (HPV)6.2 million new infections each year2 HPV strains cause 70% of cervical cancerPertussis10,454 cases reported in 2007 (3152 in adults)Most severe in infants*Source often older child or adultShingles500,000 to 1 million cases annually; lifetime risk ~32%Shingles and postherpetic neuralgia increase with ageDespite the major successes seen with immunizations in the last century, VPDs continue to cause substantial morbidity and mortality among adults.Influenza: complication rates are highest among the very young and the elderly. More than 40% of excess hospitalizations and about 90% of excess respiratory and circulatory deaths during influenza seasons occur among the elderly.Invasive pneumococcal disease: more than 50,000 cases of pneumococcal bacteremia occur every year, with highest rates in the very young and elderly. Pneumococci account for about 1/3 of community-acquired pneumonia and about half of hospital-acquired pneumonia in adults. Bacteremia occurs in about 25% to 30% of patients with pneumococcal pneumonia. Case fatality rates can be as high as 60% in the elderly.Hepatitis B: each year there are about 78,000 hepatitis B virus infections in the US. The incidence is highest among young adults, and the most common route of transmission is by sexual contact. While most adults with hepatitis B fully recover, complications can include fulminant acute hepatitis (occurs in 1% to 2% with acute hepatitis with case fatality rates of 63% to 93%). About 5% who become infected will progress to chronic hepatitis B that can cause cirrhosis and hepatocellular carcinoma. About 25% of persons with chronic hepatitis B will die prematurely from cirrhosis or liver cancer.HPV (human papillomavirus) is the most common sexually transmitted infection in the US. There are an estimated 20 million people infected, with about 6.2 million new cases occurring each year. Two high-risk HPV strains (16 and 18) account for 70% of cases of cervical cancer, as well as anal/genital cancers, in women and 70% of anal cancers in men. Two low-risk strains (6 and 11) are responsible for 90% of genital warts and 90% of recurrent respiratory papillomatosis in men and women. HPV is especially common among adolescents and young adults and is related to sexual behaviors such as number of sex partners and partners’ sexual history.Pertussis or whooping cough is an illness characterized by paroxysmal coughing. Since the 1980s, reported cases of pertussis have been on the rise. In 2008, more than 13,000 cases were reported across the US. In 2010, 9120 cases were reported in California alone; 9% of those cases were hospitalized, and 10 deaths were reported. Complications of pertussis can be serious, especially among infants, with the most common one being secondary bacterial pneumonia. While pertussis and its complications are most severe among the very young, adolescents and adults may also develop pertussis. Often the disease is milder than in the very young, but complications such as difficulty sleeping, urinary incontinence, pneumonia, and rib fracture can occur among older persons. Importantly, adolescents and adults can also transmit pertussis to infants and others who may be susceptible.Shingles (herpes zoster): an estimated 500,000 to 1 million cases of herpes zoster (shingles) occur in the US annually. The lifetime risk is at least 32%, with 50% of persons living to age 85 developing zoster. The risk for shingles increases with increasing age and immunosuppression. Postherpetic neuralgia and ocular or other organ involvement with zoster can occur and can be serious.CDC.

8 Vaccination Is the Best Way to Prevent and Control VPDs We have many safe and effective vaccines to prevent these and other diseases. Vaccination is, in fact, the best way to prevent and control VPDs.
9 Recommended Adult Vaccines by Age Group Recommendations for the routine use of vaccines in adults are issued by the Centers for Disease Control and Prevention (CDC). The Advisory Committee on Immunization Practices (ACIP) was established in 1964 by the Surgeon General of the US Department of Health and Human Services (DHHS) as a federal advisory committee, and it provides expert advice and guidance to the Director of the CDC and the Secretary of the US DHHS on the use of vaccines. The ACIP makes policy recommendations, subject to the approval of the Director of the CDC, regarding the use of currently licensed vaccines in the US civilian population. In making policy recommendations, the ACIP reviews many factors, including disease burden in the US population; data on safety, efficacy, and effectiveness; cost-effectiveness of the vaccine; and other data. ACIP recommendations for adult vaccines are often harmonized with recommendations of other professional organizations, such as the American College of Obstetricians and Gynecologists, the American Academy of Family Physicians, and the American College of Physicians.1Each year the ACIP reviews and updates the adult immunization schedule. The 2012 schedule was approved in October of 2011 and includes several changes and updates.It is important that the footnotes be read when using the schedule.This slide shows the part of the schedule that lists recommended immunizations by age group.Please see full reference for additional important footnote information.CDC.

Nevertheless, these vaccines are underused. Data from the 2009 National Health Interview Survey (a nation-wide survey conducted by the Centers for Disease Control and Prevention) show that vaccination rates for adults in this country are, indeed, too low. The highest vaccination rates are seen among the elderly for influenza (65.6%) and pneumococcal diseases (60.6%). Vaccination rates based on risk status (vs age-based) tend to be substantially lower. For example, where the vaccination rate for all persons 65 and older against pneumococcal disease is 60.6%, for high-risk persons younger than 65 it is only 17.5%. In addition, vaccination rates for newer vaccines such as shingles or HPV are also lower.CDC Adult Vaccination Coverage, NHIS. Available at:Accessed June 13, 2011

As can be seen in this slide, there is a substantial gap between the baseline vaccination rates and the year 2020 goals for influenza vaccinations, as well as pneumococcal, zoster, and hepatitis B vaccines, across all of the specific groups identified. Adult vaccination rates are indeed too low, and they also lag behind our national goals.USDHHS. Healthy People Available at: Accessed June 13, 2011.

18 Medicare Beneficiaries’ Reasons for Not Getting Vaccinated Lack of knowledgePersonal risk and need for vaccinationMisconceptionsAbout vaccines and VPDsNo recommendation from doctorThe CDC has published its findings addressing reasons reported by Medicare beneficiaries for not receiving influenza and pneumococcal (MMWR 1999) and influenza (MMWR 2004) vaccinations. These reports are based on data from the Medicare Current Beneficiary Survey (MCBS), which is an ongoing, nationally representative, longitudinal survey of Medicare beneficiaries.In 1996, the top reasons cited for not being vaccinated against influenza or pneumococcal disease were lack of knowledge, misconceptions about vaccines and vaccine-associated illnesses, and lack of provider recommendation. These findings are similar to findings published from other studies.For the years 1997 through 2002, the leading reasons given by Medicare beneficiaries for not receiving influenza vaccinations were consistently not knowing the vaccination was needed and concerns that vaccination might cause influenza or side effects.CDC.

19 Medicare Beneficiaries’ Reasons for Not Getting Vaccinated (cont.) This graph summarizes the results of the 1996 survey of Medicare beneficiaries citing reasons for not receiving influenza or pneumococcal vaccinations. The roles of lack of knowledge, misconceptions about vaccines, and lack of provider recommendation are highlighted in these results.Percentage aged 65 years who reported reasons for not receiving vaccinations1996CDC.

20 Consumers’ Reasons for Not Getting Vaccinated 2006 survey of 2002 peopleRandom-digit dialing, weighted responses to be representative of US populationVaccines: influenza, pneumococcal, tetanusCommonly cited reasonsI’m healthy, I don’t need itMy doctor hasn’t told me I need itMay have side effectsThe cost of vaccinations was cited less oftenIn this study conducted in September and October of 2006, 2002 consumers and 200 healthcare providers completed structured telephone interviews concerning their knowledge and attitudes about adult vaccines. Among the most common reasons cited for not being vaccinated included lack of physician recommendation and mistaken assumptions (eg, healthy people don’t need vaccinations). Concerns about possible side effects were also common. In this study, costs were cited as a reason for not being vaccinated by only about 15% of consumers.Johnson DR, et al. Am J Med. 2008;121(7 Suppl 2):S28-35.
21 Adults’ Main Reasons for Not Being Vaccinated These data are adapted from the results of the 2007 National Immunization Survey, a national telephone survey of a representative sample of US adults conducted by the Centers for Disease Control and Prevention. The top reasons given by the survey respondents for not being vaccinated were knowledge gaps (not needing the vaccine or not knowing about the vaccine), lack of provider recommendation, and concern about side effects. Cost was much less commonly cited as the main reason for not being vaccinated.*Included “Did not know about vaccine” and “Did not know I should get vaccinated”.**Included getting sick from vaccine, allergic reaction, etc.Percentage of US adults who reported reasonsfor not receiving vaccinations2007*Refers both to not knowing they should be vaccinated and not knowing enough about the vaccine.**Includes concern about getting sick from vaccine.Adapted from: Euler GL, CDC.

In this telephone survey of 1005 adults (504 men and 501 women), respondents indicated their answers to questions about their knowledge and attitudes regarding vaccines and VPDs. These results show that many adults lack knowledge or have misconceptions about vaccines and VPDs for adults. This is clearly a common theme across studies. Cost was another category studied in this survey. 22% of respondents indicated that they would not get a vaccine if they had to pay for it, and 26% indicated that vaccines are too expensive. Thus, cost also seems to be important, though concerns about safety may be more important.NFID. Saving lives: integrating vaccines for adults into routine care.Available at: Accessed June 13, 2011.
23 Who Most Influences Adults’ Decisions to Get Immunized? Ages 18-26Age 65 and OlderAll AdultsPersonal physician47%82%69%Family member33%6%19%Celebrity physician, public figure, other11%4%7%None of the aboveNo answer2%1%Results from a 2009 telephone survey of 1001 adults (500 men and 501 women conducted during February 2009) by the National Foundation for Infectious Diseases (NFID) shows the most important influencers of adults’ decisions to get immunized. Overall, physician recommendation was most often cited as the main reason that adults were vaccinated. However, responses varied somewhat by age group. For example, among young adults, while physician recommendation was most often cited at 47%, a family member was cited as a main reason by 33%. (Speculation— does this reflect the role of a parent among college-aged adults?) In contrast, among older adults, physician recommendation was cited as the main reason 82% of the time. All in all, these findings certainly highlight the importance of physician recommendation for getting adults vaccinated—a finding seen in other studies as well.NFID National Adult Immunization Consumer Survey: Fact Sheet.Available at: Accessed June 15, 2011.AMA.

24 Inclination to Get Vaccinated Is Higher if Physician Recommends Physician Recommendation?Impact on VaccinationYes87% are very or somewhat likely to get vaccinatedNo55% would not get vaccine unless recommended by doctorIn this slide, we illustrate in a somewhat different way the importance of provider recommendation for adult vaccination. In a 2007 national telephone survey of adults, the NFID found that the vast majority of respondents confirmed that interactions in their provider’s office were a key factor for their vaccination decisions; 87% reported that they would be very or somewhat likely to get vaccinated as long as their physician made the recommendation. On the other hand, 55% said they would not get vaccinated unless their doctor recommended it.(The survey was conducted on a sample of 1005 adults [504 men and 501 women] during October 2007.)CDC.

25 Vaccination Rates Among High-Risk* Patients With Negative Attitudes Provider Recommendation Translates Into Higher Vaccination Rates (Even for Patients With Negative Attitudes)Vaccination Rates Among High-Risk* Patients With Negative AttitudesVaccination Rate (%)In this slide, we illustrate how provider recommendation can translate into actual (vs intended) vaccination behavior. 364 high-risk outpatients responded to a mail survey conducted in (High-risk patients were those ages 65 and older, or those having heart disease, lung disease, diabetes, or other serious illness.) Among those respondents who reported negative attitudes towards influenza or pneumococcal vaccination, vaccination rates were low if they did not receive a provider recommendation to get vaccinated. In contrast, even with their negative attitudes, if their physician or nurse recommended vaccination, then their vaccination rates were in excess of 80%. Provider recommendation makes a big difference!*High-risk patients were those ages 65 and older or those having heart disease, lung disease, diabetes,or other serious illness.Nichol KL, et al.

28 To Improve Vaccination Rates, Providers Should … Know the factsRecommend vaccinations to your patientsGet organized and use systems approachesEnsure offering and administration of vaccinesAutomatic processes that empower nurses are effectiveAddress convenience, efficiency, and durabilityEvaluate and improve processesConsider new paradigmsNew venuesExtend vaccination seasonPractice what we preach (get vaccinated!)Healthcare providers are key people in ensuring that adults get vaccinated. In order to be effective in this role, healthcare providers shouldEnsure that they do know the facts—VPDs are bad for adults and vaccines (as recommended by ACIP) are good for adults. This includes being aware of the clinical manifestations and complications of VPDs, risk groups for the diseases, the target groups for vaccination, and the safety track records for the vaccines. Healthcare providers can keep up-to-date using a variety of resources, including materials available on the CDC’s Web site, as well as materials available on many state health department Web sites.In addition to being knowledgeable about adult VPDs and vaccines, healthcare providers should recommend these vaccines to their patients. Patients time and again report that a healthcare provider’s recommendation is among the most important reasons that they are vaccinated. Such recommendations should be clear and definite. “You are at risk for this disease. There is a safe and effective vaccine to help prevent this disease, and I recommend that you get vaccinated.”In addition to a provider’s recommendation, other office-based strategies that use systems-based approaches to automate processes and enhance efficiency can be highly effective.Evaluation and feedback within a practice are also important for quantifying just how well we are doing and for identifying gaps in our performance vs goals (eg, tracking numbers of vaccine doses used compared to numbers of patients seen, or conducting chart audits to identify how often vaccines are given). This is a key component of process improvement activities.It is also important to keep an open mind about new paradigms—if the logistics of vaccine delivery are too difficult for our practice, can we refer patients to another location? For seasonal vaccines such as influenza vaccination, can we extend the time period during which we offer vaccine?Finally, for providers it is important that we are vaccinated ourselves. This is important for the protection of our patients—for example, with influenza vaccination. It is also important because vaccinated healthcare providers are also more likely to vaccinate their patients.Nichol KL. Cleve Clin J Med. 2006;73(11):

30 Types of Vaccines Inactivated (“dead”) Live Inactivated whole cell or subunitTIV/flu shotHepatitis A and BAcellular pertussisHPVPolysaccharide-basedPneumococcalMeningococcalToxoidsTd/TdapLiveMMRVaricella/zosterLAIV/flu vaccine nasal sprayThere are two basic types of adults vaccines available—inactivated and live attenuated—and it is important for healthcare providers to be aware of the differences between them. The inactivated (or “dead”) vaccines can be composed of either whole cells or fractions of them. Live attenuated vaccines contain modified and weakened organisms that retain the ability to replicate and induce immunity, but generally do not have the ability to produce illness. Both types of vaccines produce immune responses in the person being vaccinated, but the live attenuated vaccines may produce an immune response that is virtually identical to the immune response seen with natural infection. Live attenuated vaccines should generally be avoided in pregnant women or patients who are immunocompromised. However, inactivated vaccines are generally acceptable for immunocompromised patients.

31 How Can Healthcare Providers Keep Up on Adult Vaccinations? Adult Immunization Schedule (updated annually)ACIP recommendations for each vaccineVaccine information statements (VIS)Lots of other information on VPDs, vaccine safety, brochures, posters, and how to store and administer vaccinesThe Immunization Action Coalition has lots of useful information for healthcare providersThere are many online resources available to healthcare professionals to help them keep up-to- date on adult VPDs and vaccinations. Of course, the primary site for definitive information is the Centers for Disease Control and Prevention. On their Web site you can find current information including immunization schedules, detailed ACIP recommendations for each vaccine, vaccine information statements (VIS) that should be used to educate patients about the vaccines and any potential contraindications or side effects prior to vaccination, as well as a wealth of other useful materials on VPDs, vaccine safety, and how to store and administer vaccines. There are also downloadable brochures, posters, and other materials.In addition to the CDC, there are many other useful sites, including many state health departments.Another useful Web site for finding information on adult vaccinations is the Immunization Action Coalition (IAC) Web site, which prepares and publishes vaccination information specifically for healthcare professionals. The IAC receives funding from the CDC and works closely with various people at the CDC as they develop their materials.

Data in this slide summarize the results of a nationwide survey of 200 healthcare providers (100 primary care physicians, 34 RNs, 33 PAs, and 33 NPs). In this study, 85% or more recommended tetanus vaccinations to all adults. But recommendations for influenza and pneumococcal vaccinations were much less common. These responses suggest a real opportunity for improvement.200 providers surveyed.Johnson DR, et al. Am J Med. 2008;121(7 Suppl 2):S28-35.
34 Reasons for Not Receiving Influenza or Pneumococcal Vaccinations Beware of Assumptions!Reasons for Not Receiving Influenza or Pneumococcal VaccinationsCited by HCPsCited by ConsumersFear of needles>65%<20%Cost>60%15%HCPs should beware of assumptions about why patients may not be vaccinated. In a concurrent nationwide survey of healthcare professionals (N=200) and consumers (N=2002), both were asked about reasons for adults not being immunized. As can be seen here, HCPs much more often cited patients’ fear of needles or cost than the consumers reported (caveat: these data are from two different surveys; therefore, responses should be compared with some caution). These findings reinforce the importance of an HCP making that recommendation—even if they anticipate other concerns on the part of their patients.Johnson DR, et al. Am J Med. 2008;121(7 Suppl 2):S28-35.
36 Missed Opportunities Missed opportunities are common More than 50% of patients needing an influenza vaccine had at least one visit with a missed opportunity to vaccinateAmong persons needing pneumococcal vaccination, there were 10.7 missed opportunity visits over 3 yearsPatient refusals uncommonIt turns out that missed opportunities to vaccinate adults occur frequently within the healthcare setting. In this study, medical records for 217 elderly adult patients from 7 primary care practices were reviewed to assess adult vaccination rates for influenza and pneumococcal vaccines as well as missed opportunities to vaccinate patients. The results clearly demonstrate that missed opportunities are frequent and may contribute to low vaccination rates for adults. More than 50% of these patients who needed influenza vaccine had at least one healthcare provider visit with a missed opportunity. Among patients who needed pneumococcal vaccination, there were an average of 10.7 outpatient visits over a three-year period where an opportunity was missed to vaccinate. The reasons for these missed opportunities were not explored in this study, but they may have included the healthcare provider forgetting, a lack of time or resources, or poor records. Regardless of the reason for the missed opportunities, it is clear that vaccination rates could be higher if fewer opportunities to vaccinate at clinic visits were missed.Nowalk MP, et al. J Am Board Fam Pract. 2005;18(1):20-27.
37 Practical Barriers to Vaccinating Adults in the Office Setting Knowing what is recommended for whomHaving time to do itRemembering to do itHaving adequate personnel to do itThere are a number of practical barriers that have been reported by primary care practitioners that undoubtedly contribute to missed opportunities. These include understanding the vaccine recommendations (what is recommended for whom), having sufficient time to assess and counsel patients, having sufficient personnel in the practice to vaccinate the patients, and simply remembering to address vaccinations when patients come in with other pressing acute or chronic medical conditions.Nichol KL, Zimmerman R.

They may include, for example, a combination of educational interventions for patients and providers along with standing orders or reminders. The Task Force on Community Preventive Services has conducted systematic reviews to identify interventions that are effective in increasing adult vaccination rates. They have found strong evidence that healthcare system- based interventions when used in combination can significantly improve vaccination rates. The interventions that they identified are summarized here. They recommend at least one intervention to increase demand along with one or more interventions to enhance access and/or interventions directed at vaccination providers or systems.CPS Task Force.

At this medical center, influenza vaccination rates for elderly patients at baseline were less than 10% (measured in the early 1980s when national vaccination rates were very low). After an educational intervention directed at providers, vaccination rates increased to nearly 30%. But it wasn’t until a multifaceted program was implemented utilizing the elements listed above that vaccination rates increased to 61% in the first year of the multifaceted program and to almost 90% after the 10th year of the program.Nichol KL.

42 Standing Orders Are Often Key Components of Success Consistently among the most effective kinds of interventions to increase vaccination ratesDefinition: policy/procedure/written order that allows qualified nurses, pharmacists, and other healthcare professionals (as allowed by state law) to assess and vaccinate patients who meet certain criteriaEliminate need for direct physician involvement with each patientEliminate need for individual physician’s order for each patientAppropriate settings: outpatient, inpatient, emergency department, long-term care, etcA critical component of the 10-year program just described was the implementation of standing orders that allowed nurses at the medical center to assess patients and then offer and administer vaccines to them without the direct involvement of a physician at the time of vaccination. This allowed for the systematic review and assessment of patients at the time of check-in, thereby avoiding the need for the provider to try to remember to address vaccination during the visit. Furthermore, the standing orders were used to allow nurses to staff the walk-in clinics (similar to a public health clinic model) without having to involve a physician with each patient. Standing orders have consistently been shown to be among the most effective interventions in other studies as well—including not only the outpatient setting, but also inpatient settings, emergency departments, and long-term care. They have also been successful for many different types of vaccines.McKibben LJ, et al. MMWR Recomm Rep. 2000;49(RR-1):15-16.
43 Influenza Vaccine Offering Rates by Type of Intervention Standing Orders Are More Effective than Provider Education or Provider Reminders for InpatientsInfluenza Vaccine Offering Rates by Type of InterventionRates (%)As mentioned, standing orders can be highly effective in settings other than the outpatient clinic. This slide summarizes data from a pilot project involving 6 hospitals in northern Minnesota. Two of the hospitals chose provider education as their intervention of choice to increase influenza vaccine offering rates, two chose chart-based reminders to the providers to order the vaccine for their high-risk patients, and two chose to use standing orders. The standing order hospitals had the highest vaccine offering rates by far.Provider EducationProvider ReminderStanding OrdersCrouse BJ, et al. J Fam Pract. 1994;38(3):

There were 1874 respondents to this survey. As can be seen, perhaps somewhat surprisingly, not all of them reported that they very strongly recommend influenza or pneumococcal vaccinations to their elderly patients—a group for whom both vaccines are recommended. The most commonly used interventions were patient education materials in the clinic. Fewer than 30% reported using standing orders.Nichol KL, Zimmerman R. Arch Intern Med. 2001;161(22):
46 Physician Practice and Interest in Selected Strategies for Influenza Vaccinations Doing AlreadyWould TryPatient reminders23%53%Walk-in clinic67%19%Policy to assess status at each visit48%31%Standing orders33%36%Clearer vaccine guidelines51%Registry7%56%A national survey of PCPs conducted about a year (in 2000) later showed similar results for the use of patient reminders and standing orders. In this study, investigators asked whether the physicians were using the strategy already or would be willing to try the strategy. For standing orders, 33% were already using them and a further 36% would be willing to try them for a total of 69% either using or willing to try this effective strategy. Likewise, for patient reminders, 23% were already using them and an additional 53% would be willing to try for a total of 76% either using or willing to try patient reminders. These findings suggest that healthcare providers are often not opposed to using selected strategies even if they are not currently using them. Interestingly, however, another nationwide survey of primary care practitioners conducted about a decade later (2009) found that, by then, only 42% were consistently using standing orders for influenza vaccination of adults.1 There hasn’t been much progress over the past decade!Szilagyi PG, et al.

We encourage their use whenever the vaccine is given, but they must be used when the vaccine was purchased under CDC contract. The legal basis for this is not the NCVIA, but a “Duty to Warn” clause in CDC’s vaccine contracts. These VIS are identical to those for the NCVIA vaccines, except they do not bear a reference to the law (42 U.S.C.§300aa-26) and do not contain information about the National Vaccine Injury Compensation Program.VIS for vaccines not covered by the NCVIA (as of June 2009) and the dates they were issued areAnthrax: 3/10/10Japanese Encephalitis (JE-VAX): 3/1/10; Japanese Encephalitis (Ixiaro): 3/1/10Pneumococcal Polysaccharide: 10/6/09Rabies: 10/6/09Shingles: 10/6/09Smallpox: 1/16/03Typhoid: 5/19/04Yellow fever: 11/9/04VIS were once available for these vaccines that are no longer used in the USRotavirus (discontinued vaccine used in )Lyme diseaseCDC.

51 Immunizations and Healthcare Workers (HCWs) “First do no harm”Recommended vaccinations/immunityInfluenzaMMRHepatitis BVaricellaTdapSpecial situationsMeningococcal for microbiologists with potential for exposureOther vaccinations based on personal risk characteristicsIn addition to making sure our patients are vaccinated, it is also important for healthcare workers (HCWs) to ensure that they are also up-to-date on their vaccinations. For HCWs, it is especially important to have immunity to certain VPDs in order to protect our patients and avoid the possibility that we might expose vulnerable patients to a VPD. In addition, of course, vaccinations can help to reduce personal illness and reduce absenteeism. Finally, HCWs who are vaccinated may also be more likely to vaccinate their patients.Immunization Action Coalition.
