Practical Approaches for Optimizing Childhood Immunization Rates
Educational Learning Objectives At the conclusion of this presentation, the participant should be able to: Acknowledge the indications and recommendations for current vaccines and vaccine schedules across childhood populations Address immunization barriers frequently encountered during patient/caregiver communications regarding safety, efficacy, and possible misinformation Implement strategies for improving immunization rates within one’s clinical practice, taking into account current immunization schedules and guidelines
Stay current with the immunization schedule, recommendations Identify and address barriers Educate parents Address safety concerns Implement organizational & systems strategies Expand access, eg, walk-in “shot clinic” Your recommendation is important! Important Considerations for Increasing Childhood Vaccination Rates

Vaccination Coverage Children 19–35 Months, United States, National Immunization Survey CDC. MMWR Morb Mortal Wkly Rep. 2010;59(36):1171-1177.
Recent Updates in Child Schedule Rotavirus –Contraindication: infants with severe combined immunodeficiency (SCID) Hib –Matching products with primary vs booster doses Pneumococcal –Integration of PCV13 Polio –Emphasize importance of booster dose at 4 to 6 years Influenza –Universal annual vaccination ≥ 6 months MMR –No preference MMR or MMRV for 1 st dose (age 12 to 47 months) Hep A –Family members of international adoptees Tdap
Hepatitis B Dose 3 should be administered ≥ 16 wk after dose 1 Combination vaccines cannot be used for the birth dose Adapted from Table 1, ACIP General Recommendations on Immunization: MMWR Recomm Rep. 2006;55(RR-15):1-48. *HB Immunoglobulin should also be administered at birth for infants whose mothers are HBsAg positive Dose # Recommended Age Minimum Age Recommended Interval Minimum Interval 1Birth*Birth1–4 mo4 wk 21–2 mo4 wk2–17 mo8 wk 36–18 mo24 wk

Offit PA, Moser CA. Pediatrics. 2009;123(1):e164-e169. Critique of Dr. Bob Sears’ Alternative Schedule ArgumentThe Truth Vaccine-preventable diseases are not that serious and are often not seen in practice. Vaccine-preventable diseases are serious and can result in death. Anecdotal experience in practice does not trump national surveillance data. Vaccines are recommended for protection of the public at large, not individuals. Every individual benefits from receiving vaccines– they become immune to the disease and, as long as others are immunized, they have less chance of exposure. Vaccines are not adequately tested for safety. Vaccines are among the most thoroughly tested pharmaceuticals. The post-licensure safety net is robust. Reports in VAERS and language in the Package Insert (PI) constitute accurate profiles of vaccine side effects. VAERS reports do not establish causality and the PI lists any reported events, whether causally related or not. Parents’ fears should be indulged by offering alternative schedules. Parents’ fears should be assuaged by explaining the scientific findings.
