Killer T cells boost immunity to coronavirus variants: study

[Klaralven]

The emergence of coronavirus variants has provoked concern about their impact on the effectiveness of vaccines, and whether people who were previously infected might be more susceptible to reinfection.

But in welcome news, a new study on Tuesday showed that a key player in the immune response, called the "killer T cell," remained mostly unaffected.

The finding is encouraging because although these white blood cells are not a first line defense against infection, they can help prevent severe disease.

Scientists at the National Institutes of Health and Johns Hopkins University analyzed blood samples from 30 people who had contracted and recovered from Covid-19 prior to the emergence of variants.

They published their findings in Open Forum Infectious Diseases, an Oxford University Press journal.
