With ex­pan­sive Covid-19 clin­i­cal plan in full gear, Ox­ford team re­ports pos­i­tive an­i­mal da­ta on ade­n­ovirus-based vac­cine

A few days af­ter the first UK vol­un­teers were dosed with a Covid-19 vac­cine de­vel­oped at Ox­ford Uni­ver­si­ty’s Jen­ner In­sti­tute, the team said a cru­cial an­i­mal study has come back pos­i­tive.

The pre­lim­i­nary re­sults, first re­port­ed by the New York Times, mark the sec­ond pos­i­tive ex­per­i­ment of a vac­cine can­di­date in­volv­ing rhe­sus macaque mon­keys dis­closed in re­cent days. Chi­na’s Sino­vac post­ed promis­ing da­ta with its in­ac­ti­vat­ed virus vac­cine can­di­date on a preprint serv­er last Mon­day. No­tably, US biotech Mod­er­na skipped the an­i­mal tri­als al­to­geth­er be­fore jump­ing in­to hu­man tri­als, with the promise to run those stud­ies in par­al­lel.
