The US Centers for Disease Control and Prevention is publishing a new study in the June issue of the American Journal of Preventive Medicine that shows that up to 25% of children 19 - 35 months old were missing doses or were not given the doses according to schedule.
This study was based on doses kids received in 2003 and 2004, at which time a toddler up to 18 months old should have received about 14 shots related to several different vaccines. Today, there are even more shots recommended.
About 72% of children in the study were found to have gotten all of their doses in full and on time. That total is 9% points lower than if only missing doses were considered.
19% were found to be missing one or more doses, and 8% had received a dose too young or too close to the previous dose.
