Question

Why buffer used is different in bcg and measels vaccine?

Answer 1

The main purpose of the controled assay on a combination of B.C.G. and measles vaccine was to ascertain whether these two vaccines could be administered on young children in simultaneous injections, in two different parts of the body and on the same day, and whether in that case they led to rates of haemagglutination inhibitory antibodies against measles on the one hand, and induration diameters of Mantoux's intradermoreactions against B.C.G. on the other, not inferior to rates and diameters obtained when using the same vaccines separately. This survey, carried out in Cameroon, involved one thousand individuals. It confirms the suggestion that the two vaccinations may be carried out simultaneously when circumstances require an early and total protection of a child population with minimum sanitary stress
