Early Promise for COVID Vaccine Taken as Pill

May 6, 2022


An experimental COVID-19 vaccine in pill form could be a win-win, as it not only protects against infection but also limits the airborne spread of the virus, tests in lab animals show.

The current vaccines reduce the risk of serious COVID-19 illness and hospitalization but aren’t foolproof armor against infection with SARS-CoV-2.

“Considering most of the world is under-immunized — and this is especially true of children — the possibility that a vaccinated person with a breakthrough infection can spread COVID to unimmunized family or community members poses a public health risk,” said study leader Stephanie Langel, of Duke University in Durham, N.C.
