Could a booster make your flu shot work better? new study investigates
NCT ID NCT03945825
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at whether adding special ingredients called adjuvants to two standard flu vaccines (Fluzone and Flublok) could make them work better. About 240 healthy adults aged 18 to 45 received either a regular flu shot or one with an adjuvant. Researchers checked for side effects and measured immune responses in blood samples over a year. The goal was to see if the adjuvanted vaccines were safe and produced stronger protection against the flu.
