In Hyderabad, India, diphtheria is common among children aged 5–19 years. On account of low coverage of diphtheria vaccine boosters recommended under the universal immunization programme, a large proportion of children were susceptible/partially immune against diphtheria and/or tetanus. We evaluated immunogenicity and safety of single dose of indigenously developed tetanus–diphtheria (Td) vaccine (diphtheria–toxoid ≤5 Lf) among 483 school children from Hyderabad aged 7–17 years and susceptible/partially immune against diphtheria and/or tetanus. Serological testing 6 weeks after vaccination indicated that vaccine was highly immunogenic with >96% sero-protected against both antigens. The immune response observed indicated a booster response to previously acquired immunity. Administration of additional dose of Td vaccine to the older school children and replacing the tetanus toxoid vaccine with Td in the school health programme would considerably reduce diphtheria burden in Hyderabad.
