The researchers believe that the new variant of the virus is unlikely to have an impact on the effectiveness of vaccines.

Since the early days of the pandemic, scientists have been paying attention to changes in the genetic code of the coronavirus.

All viruses mutate naturally and SARS-CoV-2, the cause of covid-19 disease, is no exception: it is estimated that it accumulates one or two changes per month.

As the scientist explained to BBC Mundo Adriana Heguy, director of the Center for Genome Technology at the Grossman School of Medicine, New York University, a few months ago, mutations occur in all organisms.

“As the cells of any organism replicate, they acquire mutations,” he said.
