Immunization Schedules

Recommendations from the National Advisory Committee on Immunization (NACI)

Few measures in preventive medicine are of such proven value and as easy to implement as routine immunization against infectious diseases. Immunization carried out as recommended in the following schedules will provide good basic protection for most children against the diseases shown.

Following a standard schedule ensures that the maximal achievable protection is achieved. However, modifications of the recommended schedule may be necessary because of missed appointments or inter-current illness. Interruption of a recommended series does not require starting the series over again, regardless of the interval elapsed. Children, youth and adults with interruptions to their vaccines should be vaccinated to complete the appropriate schedule for their current age.
