National, state, and local area vaccination coverage among children aged 19-35 months --- United States, 2009

MMWR Morb Mortal Wkly Rep. 2010 Sep 17;59(36):1171-7.


Since 1994, the National Immunization Survey (NIS) has been collecting data to monitor childhood immunization coverage. This report describes the 2009 NIS coverage estimates for children born during January 2006--July 2008 and focuses on the more recently recommended vaccines (i.e., hepatitis B [HepB] vaccine birth dose, hepatitis A vaccine [HepA], pneumococcal conjugate vaccine [PCV], and rotavirus vaccine) for children aged 19--35 months. The most recent NIS data indicate that vaccination coverage increased in 2009 compared with 2008 for HepB birth dose (from 55.3% to 60.8%) and HepA (from 40.4% to 46.6%), but coverage for PCV (≥4 doses) remained stable (80.4%). Full coverage for rotavirus vaccine was 43.9% among children born within 2 years of licensure. Coverage for poliovirus (92.8%), measles, mumps, and rubella (MMR) (90.0%), hepatitis B (HepB) (92.4%), and varicella (VAR) (89.6%) vaccines continued to be at or near the national health objective of 90%, although coverage for MMR and HepB vaccines decreased slightly in 2009. The percentage of children who have not received any vaccines remained low (<1%). Parents and primary-care providers continued to ensure that children were vaccinated, in spite of interim recommendations to suspend the booster dose of Haemophilus influenzae type b vaccine (Hib) because of a national shortage, and heightened public awareness of controversies in vaccine safety.
