Researchers have found that children's antibodies can effectively fight out Covid-19 infection, and that kids could be an underutilised source of potential antibody therapies to counteract the "ever-evolving" SARS-CoV-2 virus.

The team at Vanderbilt University Medical Center (VUMC) in the US found that children's antibodies displayed high levels of neutralisation and potency against variants of the Covid virus, even when they had not previously been exposed to or vaccinated against those variants.
