Primary Outcome Measures

Name	Time	Method
Days under-immunized	2 years	Days under-immunized is a metric to identify immunization delay. For each vaccine dose calculate the difference between when the vaccine dose was actually administered and when the vaccine dose should have been administered according to the Advisory Committee on Immunization Practices (ACIP) schedule. That difference is summed across all doses and vaccines for a total number of days under-immunized for each child. Total days under immunized was calculated 200 days after life or after enrollment. If someone had 0 days at that time they were considered "up to date".
