Vaccines help your T cells fight covid.

[YAX]

T cells, the body’s weapon against virus-infected cells, were primed enough by vaccination that they defended against omicron in separate studies from Erasmus University in the Netherlands and the University of Cape Town in South Africa.

The findings could help explain why the wave of omicron cases hasn’t so far caused a surge in mortality from South Africa to the U.S. and the U.K. Unlike antibodies, T cells can target the whole of the virus’s spike protein, which remains largely similar even in the highly mutated omicron.
