18 months old child, who has received one dose of DPT and OPV at 2 months of age. What will be your next immunization plan :
Restart immunization schedule, as per age
Measles, BCG, booster dose of DPT and OPV
Measles, booster dose of DPT and OPV
BCG, 2ND dose of DPT and OPV
A lapse in the immunization schedule does not require reinitiation of entire vaccine series. Immunization should be given at the next visit in the usual doses assuming that the minimum interval has already elapsed and the imunization should be completed at the next available opportunity".
D.P.T. and oral polio vaccine which the child already had should be considered as the first dose.
The child would need further 2 doses of this vaccine to complete the primary vaccination.
Booster doses are administered, once the primary immunization is complete. Thus you cannot administer booster doses of D.P.T. and O.P.V. as their primary immunization is not complete.
