This study of 724 13-year-old schoolgirls in the County Borough of Reading showed that approximately 25% were susceptible to rubella. 96·1% of the 129 seronegative girls and significant numbers of girls with low rubella HAI antibody titres responded to subcutaneous vaccination with Wistar RA. 27/3 rubella vaccine. The incidence of most reactions after vaccination was similar in those who responded to vaccine and those who were initially immune but did not develop rising antibody titres, but rash, lymphadenopathy and headache occurred significantly more frequently in the susceptible group.
