NCT ID NCT07365826
First seen Feb 01, 2026 · Last updated May 07, 2026 · Updated 10 times
Summary
This study tests a new vaccine called VAX-31, which targets 31 types of bacteria that cause pneumonia and other infections. Researchers want to see if it is safe and works well when given at the same time as the seasonal flu shot in healthy adults aged 50 and older. About 1,390 participants will receive either both vaccines together or separately, and their immune responses and side effects will be compared over 7 months.
