DTP immunization

Routine immunization

  • Minimum age: 6 weeks
  • The first booster (4th dose) may be administered as early as age 12 months, provided at least 6 months have elapsed since the third dose.
  • DTaP vaccine/combinations should preferably be avoided for the primary series.
  • DTaP may be preferred to DTwP in children with history of severe adverse effects after previous dose/s of DTwP or children with neurologic disorders.
  • First and second boosters may also be of DTwP. However, considering a higher reactogenicity, DTaP can be considered for the boosters.
  • If any ‘acellular pertussis’ containing vaccine is used, it must at least have 3 or more components in the product
