My kid current age is 18 months. In government centres at 18 months they are giving only DPT and OPV booster vaccines and they are not giving HIB booster. So we are planning to go to private hospital to take HIB booster also. But in private hospital they are giving HIB in combination vaccines like PENTAVAC or HEXAXIM. Initial DPT(in the form of PENTA), 3 doses we taken at government centre and those are serum institute vaccines. So now at 18 months can we take PENATVAC or HEXAXIM at private hospital ? Please clarify.
