By convention, BCG is given into the skin over the right deltoid. This helps to find the scar.

DTP and Hib are given into the left thigh or into the left deltoid in older children. The vaccines can be combined and given together as they do not interfere with each others’ action.

Hepatitis B is given into the right thigh as it is best not given at the same site as Hib.

Measles is usually given into right thigh or right deltoid in older children.

New, special vaccines consisting of combinations DPT, Hib, HepB and killed polio can be given together. Single vaccines must not be combined in the same syringe (except DPT and Hib).
