Summary
This study tested a new vaccine called BK1310 in 267 healthy infants to see if it protects against tetanus, diphtheria, pertussis, polio, and bacterial meningitis as well as existing vaccines. Infants received three doses, and researchers measured their immune responses. The goal was to confirm the new vaccine is safe and effective for routine infant immunization.
