DPT (Diphtheria, Pertusis, Tetanus vaccine)                                               

        Recommended schedule:

-   Three primary doses at 6, 10 and 14 weeks and two boosters at 15–18 months and 5 years.

-   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 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.

    Catch-up schedule:

-  The 2nd childhood booster is not required if the last dose has been given beyond the age of 4 years

-   Catch up below 7 years: DTwP/DTaP at 0, 1 and 6 months;

-   Catch up above 7 years: Tdap, Td, and Td at 0, 1 and 6 months.
