![]() ![]() Their natural immunity would be no match for this powerful version. ![]() population that has recovered from COVID-19. This new mutation might even be a threat to the one-third of the U.S. Vail believes a new variant could materialize that is even more transmissible, even though the delta variant already is five times more contagious than the original version of SARS-CoV-2. When a virus has so many opportunities to evolve, it increases the odds that a dangerous new version will arise. But with so many people declining to get vaccinated against COVID-19, they become living "mutation labs" for SARS-CoV-2, according to Newsweek. Most viruses are slow to mutate, and few variants emerge that spread widely in the course of a year. "The fourth one was delta, which didn't have as strong an evading mutation, and that's the one that spread." "There were four variants that arose in India, and three of them had some ability to evade immunity," Vail told Newsweek. Vail explained that this mutation process is how the delta variant emerged and started spreading. The resulting mutation can give the virus different characteristics. Variants develop when viruses like SARS-CoV-2 replicate inside the body but fail to make an exact copy of their genetic material. Newsweek Magazine recently published an article featuring Eric Vail, MD, director of Molecular Pathology in the Department of Pathology and Laboratory Medicine at Cedars-Sinai, discussing potential future variants of SARS-CoV-2, the virus that causes COVID-19.
