ROCKVILLE, Md. Despite concerns regarding COVID variants, researchers at the National Institute of Allergy and Infectious Disease found an active T cell in blood samples of 30 people who had previously contracted and recovered from the virus before the variants emerged.
When SARS-CoV-2 (the virus that causes COVID-19) variants surfaced in late 2020, concerns arose that they would elude protection from prior infections or vaccines, potentially making reinfection more likely or vaccines less effective. However, researchers found one T cell, CD8+, that remained active against the virus.

Chicago: A critical component of the immune system known as T cells that respond to fight infection from the original version of the novel coronavirus appear to also protect against three of the most concerning new virus variants, according to a U.S. laboratory study released on Tuesday.
Several recent studies have shown that certain variants of the novel coronavirus can undermine immune protection from antibodies and vaccines.
But antibodies – which block the coronavirus from attaching to human cells – may not tell the whole story, according to the study by researchers at the National Institute of Allergy and Infectious Diseases (NIAID). T cells appear to play an important additionally protective role.
