The chief infectious disease specialist of the United States, Anthony Fauci, named a factor affecting the effectiveness of vaccines against COVID-19. Reported by CNN.
Various genetic variants of the virus could reduce the potential of existing vaccinations, he said. Nevertheless, the infectious disease specialist explained that there is a certain “safety cushion” that allows vaccines to still remain to a certain extent effective. He stressed that the United States is taking new mutations of the virus very seriously.
Earlier, US President Joe Biden saw a “light at the end of the tunnel” in the coronavirus pandemic following the approval of Johnson & Johnson's emergency COVID-19 vaccine by the Food and Drug Administration (FDA).
Johnson & Johnson's vaccine is the third approved vaccine in the United States after Pfizer / BioNTech and Moderna.
The drug is manufactured by Janssen Pharmaceutica, a division of Johnson & Johnson. Unlike the vaccines already approved in the USA, this vaccine is a vector vaccine, similar to the Russian Sputnik V and the Anglo-Swedish AstraZeneca. Unlike other US-approved vaccines, this one requires only one injection, not two.
