Scientists are hard at workplace test out whether mutations find in young variant of the coronavirus could get around the immunity offer by currently develop vaccines . The first results from this work are encouraging : They suggest that the Pfizer vaccine is still effective against one authoritative mutation found in these variants . However , more research is still needed before we should be completely reassured .
The preliminary results werereleasedthis week on the preprint internet site bioRXiv by a team of scientist from Pfizer and the University of Texas Medical Branch . They collected stemma samples from people who had been fully immunize and test them against strains of the virus carrying the N501Y mutant , which has been seen in variants first obtain in the UK and South Africa and is thought to be one important reason why these strains are more transmissible . scientist have interest that the mutation could exchange the structure of the virus enough to permit it to “ escape ” sleuthing from the immune organization of survivors or vaccinated citizenry .

In the tests , the blood of these patients still leaven capable of neutralizing the N501Y strain of the virus , performing just as well as against other discrepancy . That indicates that this one genetic mutation alone wo n’t protect the computer virus from our existing weapons . The team has also tested other mutations seen in the UK or South Africa variants and find interchangeable results .
“ So we ’ve now tested 16 different mutations , and none of them have really had any significant impact . That ’s the honest tidings , ” discipline generator and Pfizer scientist Philip DormitzertoldReuters Friday . “ That does n’t mean that the 17th wo n’t . ”
Indeed , there has n’t been research done yet on another perturbing chromosomal mutation seen in the South African stochastic variable , call E484K. And while it may be hard for any single mutation to affect vaccine efficacy , expert havewarnedthat multiple variation in a variant could collectively change it enough to nullify vaccinum - provided antibodies , at least partially weakening a vaccine ’s effectualness . In other lyric , these findings are bright , but there ’s still a lot of double - checking to be done .

Dormitzer and his team — and no doubt other scientist — will continue to test the vaccine against new sport and variants , with information from this research said to be available in the next few workweek . Meanwhile , the real Earth could provide some useful information in the near future . So far , around 17 million people globally havereceivedat least one dose of a covid-19 vaccine ( most take two dot ) , include 6.25 million Americans . In the thick of a still - raging pandemic , more grammatical case of these stochastic variable are beingreportedaround the world . If our vaccinum are n’t working as in effect as they ’re look to because of these Modern rendering of the computer virus , we ’ll know shortly enough .
