Many young children do not adhere to the early childhood immunization schedule recommended by the CDC’s Advisory Committee on Immunization Practices, study findings showed.

Robert A. Bednarczyk, PhD, an assistant professor of global health and epidemiology at the Emory Vaccine Center, and colleagues analyzed data from the 2014 National Immunization Survey (NIS) and found that 63% of children aged between 19 and 35 months were vaccinated consistent with ACIP’s recommended schedule, 23% followed an alternate pattern and about 14% followed an unknown pattern.
