SUMMARY

This study investigated the association between vaccination with the hepatitis B triple series vaccine (pre-2000) and subsequent developmental disability. The odds of receiving special education were approximately nine times as great for vaccinated boys as for unvaccinated boys, after adjustment for confounders. The evidence, statistically significant, suggests that boys in United States who were vaccinated with the triple series hepatitis B vaccine were more susceptible to developmental disability than were unvaccinated boys.
