Back on December 9th we discussed the quickening hunt for a Sarbecovirus vaccine. This is basically a vaccine that wouldn’t target this or that variant but the whole class of SARS-related coronaviruses. Basically the idea is you go upstream in the viral family tree to cover the whole class of contagions and potential future ones. Last night Army researchers at Walter Reed Army Institute of Research say they’ve developed just such a vaccine, or at least one that cover all current and potential variants of COVID19.
