Dramatic changes have been made in the recommended schedule for immunizations, and for a variety of reasons: greater understanding of risks associated with whole-cell pertussis vaccine; introduction of more immunogenic vaccines to prevent invasive disease caused by Haemophilus influenzae type B; a national epidemic of measles that affected many vaccinated individuals; and the failure of targeted use of vaccine in high-risk patients to reduce the occurrence of hepatitis B. Additional changes in recommended regimens can be anticipated as new products are introduced. However, for vaccines to have their greatest impact, improved adherence to recommended immunization practices is necessary. [ABSTRACT FROM AUTHOR] |
