Vac­cine re­search in ad­vanced phase

San Francisco Chronicle - - CORONAVIRU­S PANDEMIC -

Bri­tish re­searchers test­ing an ex­per­i­men­tal vac­cine against the new coro­n­avirus are mov­ing into ad­vanced stud­ies and aim to im­mu­nize more than 10,000 peo­ple to de­ter­mine if the shot works.

Last month, sci­en­tists at Ox­ford Univer­sity be­gan vac­ci­nat­ing more than 1,000 vol­un­teers in a pre­lim­i­nary study de­signed to test the shot’s safety. Those re­sults aren’t in yet but on Fri­day, the sci­en­tists an­nounced they’re ex­pand­ing to 10,260 peo­ple across Bri­tain, in­clud­ing older peo­ple and chil­dren.

If all goes smoothly, “it’s pos­si­ble as early as the au­tumn or to­ward the end of the year, you could have re­sults that al­lowed use of the vac­cine on a wider scale,” pre­dicted An­drew Pol­lard, head of the Ox­ford Vac­cine Group.

But Pol­lard ac­knowl­edged there were still many chal­lenges ahead, in­clud­ing how long it will take to prove the vac­cine works and any po­ten­tial man­u­fac­tur­ing com­pli­ca­tions.

The Ox­ford ef­fort is one of about a dozen ex­per­i­men­tal vac­cines in early stages of hu­man test­ing or poised to start, mostly in China, the U.S. and Europe. Sci­en­tists have never cre­ated vac­cines from scratch this fast, and it’s far from clear that any of the can­di­dates will ul­ti­mately prove safe and ef­fec­tive.
