Illustration of SARS‑CoV‑2, the virus that causes covid-19. T cells recognize fragments of the amino acids that make up the virus.

With the omicron variant rapidly increasing covid infections, the focus is once again on antibodies, and rightly so.

Antibodies play a critical role in fighting viruses and are important in preventing the coronavirus from infecting our cells.

This is why some countries have mounted booster vaccination campaigns in response to recent covid surges, in order to increase antibody levels.

But there’s a problem. antibodies against covid don’t persist as wellhence the need for reinforcements.
