How often must the vaccines be repeated? How many DTP boosters are required?


Please go through the Immunization schedule

DTP first booster is required at 16-24 months of age, followed by a second booster at  4-6 yrs of age. Tdap vaccine is required at 11-12 years of age to provide immunity to school going children. Boosters serve as a reminder to our immune system to fight against diseases and are equally important as the primary doses given to a newborn.

Vaccine schedules are designed after rigorous research to provide maximum benefits in terms of immunity to children. They should be followed strictly to gain complete immunity.

How often must vaccines be repeated? I’m specifically curious about the DPT booster (includes immunity to whooping coughs).
