Vastavam web: As the new variant has been surfaced that causes COVID-19, experts urged caution, saying it would take years, not months, for the virus to evolve enough to render the current vaccines impotent. They added that no one should worry that there is going to be a single catastrophic mutation that suddenly renders all immunity useless. “Some variants become more common in a population simply by luck, not because the changes somehow supercharge the virus. But as it becomes more difficult for the pathogen to survive — because of vaccinations and growing immunity in human populations — researchers also expect the virus to gain useful mutations enabling it to spread more easily or to escape detection by the immune system,” reported.
The American daily further reported that The British variant has about 20 mutations, including several that affect how the virus locks onto human cells and infects them. Muge Cevik, an infectious disease expert at the University of St. Andrews in Scotland said that these mutations may allow the variant to replicate and transmit ore efficiently. She added that the estimate of greater transmissibility is based on modeling and has not been confirmed in lab experiments. “Over all, I think we need to have a little bit more experimental data… We can’t entirely rule out the fact that some of this transmissibility data might be related to human behavior,” she said.
‘Scientists fear the latter possibility, especially: The vaccination of millions of people may force the virus to new adaptations, mutations that help it evade or resist the immune response. Already, there are small changes in the virus that have arisen independently multiple times across the world, suggesting these mutations are helpful to the pathogen,” the reported. It was reported that scientists initially thought the new coronavirus was stable and unlikely to escape vaccine-induced immune response, said Dr. Deepti Gurdasani, a clinical epidemiologist at Queen Mary University of London.
