Most U.S. Toddlers Are Being Vaccinated; Most Measles Cases Occur in Unvaccinated Persons
By Cara Adler
In 2012, vaccination coverage among U.S. children aged 19 to 35 months remained near or above the Healthy People 2020 targets of 90% for polio, hepatitis B, varicella, and measles, mumps, and rubella, according to an analysis of National Immunization Survey data reported in MMWR.
Coverage with four or more doses of diphtheria, tetanus, and pertussis vaccine, four or more doses of pneumococcal conjugate vaccine, and the full series of Haemophilus influenzae type B vaccine were below the 90% goal but remained relatively stable and high (over 80%). Less than 1% of children did not receive any vaccines. Those living in poverty were more likely to be unvaccinated.
A separate article in MMWR details 159 cases of measles reported in 16 states in 2013. Most cases (82%) were in unvaccinated individuals, and nearly all were import-associated. Eight outbreaks in communities with unvaccinated persons accounted for more than three quarters of cases.
