If a child falls behind on immunizations, is it recommended to use only minimum intervals to get the child caught up? Or should we use a minimum interval for the same vaccine only once?

If a child is behind on immunizations, the Advisory Committee on Immunization Practices (ACIP) recommends using the minimum intervals between each dose until the child is caught up. The minimum interval for a vaccine can be used as many times as necessary, until the child is back on schedule. See Table 2 of the CDC Recommended Child and Adolescent Immunization Schedule, available at www.cdc.gov/vaccines/schedules/hcp/index.html.
