MeasureTime frame
To compare the pre vaccination anti diphtheria1 antitetanus antipertussis, and anti Hib (PRP) verses 4weeks titer of after third dose. Seroprotection Attainment of antibody titers that corresponds to clinical protection. This is according to WHO established level of titers. â?¢ Seroconversion:Seroconversion will be considered if the 4 weeks after third dose post-vaccination antibody titer shows a â?¥ 4 fold rise from the pre-vaccination levels Timepoint: 0 and 84
