Summary

This study tested whether giving babies an extra measles vaccine at 4 months old, in addition to the standard shot at 9 months, could reduce deaths. Over 4,500 children in Burkina Faso and Guinea-Bissau took part. The goal was to see if early vaccination provides extra protection beyond just preventing measles.
