Can a smaller booster shot work just as well? new study tests COVID vaccine doses
NCT ID NCT05265065
Summary
This study tested whether a smaller dose of the Pfizer COVID-19 booster vaccine works as well as the full dose. It involved 601 healthy adults in Mongolia who had previously received two doses of either Sinopharm, AstraZeneca, or Sputnik V vaccines. Researchers compared the immune response and side effects of the standard booster dose versus a fractional (smaller) dose given 6-9 months after the initial shots.
