Study finds COVID booster maintains strong T cell response against Omicron

New study results posted to the medRxiv* preprint server found that COVID vaccine boosters increase immunity by enhancing T cell immune memory. In the face of the severe acute respiratory syndrome coronavirus 2 (SARS‑CoV‑2) Omicron variant, vaccinated people who had received a third booster shot maintained high T cell responses than people with naturally acquired immunity or vaccine-induced immunity from two doses of the SARS‑CoV‑2 vaccine.
