Study: Pfizer vaccine seems to work against new options.

The two viruses share a mutation known as N501Y, which scientists worry could enable the virus to avoid immune protection generated by vaccines.

Researchers made a version of vrus in the laboratory that holds that mutation. They tested against blood taken by 20 people who had received two doses of Pfizer vaccine as part of clinical trials. In this research posted online found no “reduction of neutral activity” against the modified virus.

The N501Y mutation seems to help the virus climb into human cells, which explains in part although these variants are presented as more transmitted, It says CNN, translates Periscope.

The study by Pfizer and Texas University researchers has not tested all these mutations.

In a statement last month, Pfizer has said he has performed similar tests “in various mutant variants. And so far the data was consistent at all. ”
