Could an early measles vaccine slash child deaths? trial tests the idea
NCT ID NCT01644721
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether giving an extra measles vaccine at 4 months, in addition to the standard shot at 9 months, reduces deaths in children up to age 3. Over 3,700 children in Burkina Faso and Guinea-Bissau took part. Researchers tracked survival, hospital visits, and growth to see if the early vaccine provides extra protection beyond preventing measles.
