9 in 10 Americans Not Yet Exposed to COVID
New study shows coronavirus mutates rapidly
Also on Wednesday, a new study of more than 5,000 genetic sequences of the coronavirus reveals the continued build-up of mutations in the virus, one of which may have made it more contagious, the Washington post reported.
But the researchers did not find that these mutations made the virus any more deadly.
Every mutation is a game of dice, and with transmission so widespread in the United States that the virus has had many opportunities to change, potentially with troublesome consequences, said study author James Musser of the Houston Methodist Hospital. Publish.
“We have given this virus a lot of chances,” Musser said. “There is a huge population there right now.”
The research was posted on the MedRxiv pre-print server and has not been peer reviewed. Earlier this month, a larger batch of footage was released by scientists across the UK. These scientists also concluded that a mutation that changes the structure of the “spike protein” on the surface of the virus may be the cause of the disproportionate spread of this particular strain.
David Morens, a senior virologist at the US National Institute of Allergy and Infectious Diseases, said the discovery “could have implications for our ability to control it.”
“Wearing masks, washing your hands, all of those things are barriers to transmissibility, or contagion, but as the virus becomes more contagious, it’s statistically better at getting around those barriers,” Morens explained.
Not only that, the virus may be able to reduce the durability of any vaccine, Morens added.
“While we don’t know it yet, it’s entirely possible that this coronavirus, when our population-level immunity becomes high enough, this coronavirus will find a way around our immunity,” Morens said. “If that happened, we would be in the same situation as with the flu. We will have to chase the virus away, and as it mutates, we will have to tinker with our vaccine.
Single-dose vaccine moves to larger trials
In news that could help make vaccinating all Americans against COVID-19 easier to achieve, the first coronavirus vaccine that requires only one vaccine has entered the final stages of testing in the United States , the Publish reported.
