The researchers analyzed blood from 30 people who had recovered from #COVID19 before the emergence of the new more contagious #coronavirus variants.
From those samples, they identified a specific form of T cell that was active against the virus, and looked to see how these T cells fared against the concerning variants from South Africa, the UK and Brazil.
They found the T-cell responses remained largely intact and could recognize virtually all mutations in the variants studied.
