Education of mothers on the benefits of tetanus vaccination increased immunization coverage in a randomized trial set in rural India, according to new research this week in PLOS Medicine by Timothy Powell-Jackson of the London School of Hygiene and Tropical Medicine, UK, and colleagues.

Only 51% of children aged 12 through 23 months are fully immunized in Uttar Pradesh, India. In their trial, the researchers identified 722 mothers in Uttar Pradesh with children aged 0 to 36 months who had not yet received all three doses of the DTP (diphtheria, pertussis, tetanus) vaccine. Mothers were randomized into three groups: one group received home visits with education about the health risks of tetanus in an unvaccinated child; another received home visits with education about the health benefits of vaccination; and a third group did not receive home visits.

In the group that received no intervention, 28% of children had received all DTP immunizations at the study's 8-month follow-up. In the groups that had received either type of intervention, 43% of children completed the immunization schedule (Risk Difference: 22%, 95% CI: 14% to 30%, p

Broad generalizability beyond the study setting is uncertain, and the limited sample size meant that the study was not able to exclude the possibility of modest differences between the two intervention groups, or determine which aspects of the interventions were effective. Nonetheless, the trial provides evidence of efficacy that merits further investigation. The authors state, "in contexts where knowledge and awareness are a key binding constraint, interventions that provide information to parents and carers of unvaccinated children have the potential to be a simple and cost-effective way of increasing demand for immunization."
