Scientists focus on how immune system T cells fight coronavirus in absence of antibodies

As scientists question whether the presence, or absence, of antibodies to the novel coronavirus can reliably determine immunity, some are looking to a different component of the immune system, known as T cells, for their role in protecting people in the pandemic. Recent studies show that some recovered patients who tested negative for coronavirus antibodies did develop T cells in response to their COVID-19 infection. While the studies are small and have yet to be reviewed by outside experts, some scientists now say that people who experience a mild illness, or no symptoms at all, from the new coronavirus, may be eliminating the infection through this T cell response.

Pandemic exposes scientific rift over proving when germs are airborne

The coronavirus pandemic has exposed a clash among medical experts over disease transmission that stretches back nearly a century - to the very origins of germ theory. The Geneva-based World Health Organization acknowledged this week that the novel coronavirus can spread through tiny droplets floating in the air, a nod to more than 200 experts in aerosol science who publicly complained that the U.N. agency had failed to warn the public about this risk.
