Humoral antibody responses to biannual multiantigen vaccination: report of a field trial on children in Sudan.

One hundred and sixty-six children aged 3-30/12 were enrolled in this study. Initially all children were given a single injection containing live measles vaccine, diphtheria and tetanus toxoids, inactivated polio vaccine and meningococcal, A & C polysaccharide, plus an intradermal injection of BCG. In a second visit 6 months later each child was tuberculin tested and given a second dose of all the above vaccines with the exception of BCG.
