School Health Program Immunization in India:Under India's National Immunization Schedule (NIS), school-age children receive booster doses to maintain protection against vaccine-preventable diseases. The schedule for school children is as follows:
- Age 5 years: DPT booster + OPV booster
- Age 10 years: TT (Tetanus Toxoid)
- Age 16 years: TT (Tetanus Toxoid)
The Td (Tetanus-diphtheria) toxoid is also used in this age group because immunity to tetanus and diphtheria declines as children grow older and earlier vaccine protection wanes.
Why not the others?
- BCG: Birth dose only
- MMR: Infancy and toddler schedule
- DPT: Early childhood (primary and first booster); not repeated at age 10
At 10 years under the school health program, the indicated vaccine is therefore
TT/Td.
