The Mass BCG vaccination is going on in India since 1951. A WHO/TRO BCG Assessment Team retested the groups vaccinated in Mass Campaign in 1954 and again in 1955. All India BCG Assessment Team, established under the aegis of the Indian Council of Medical Research, is asses sing the work of the Mass Campaign from 1954. The mean size of post-vaccination reaction of the retesting done in 1954 by the, WHO/TRO Assessment Team was 9.3 mm. and it ranged from 6.1 to 14.9 mm. in different groups. For the group retested in 1955 the average induration was 114 mm. and they varied from 10.8 to 14.8 mm. for different groups. The mean size of reactions for the retesting done by the Assessment Team from 1955-58 was 12.5mm. with variation between 8.3 to 16.6 mm. file lower level of allergy seen for some groups in all these results and wide group variations are a disturbing feature. Some studies have been carried out to find out the reasons for these. They will be described one by one hereafter.
