The makers of coronavirus vaccines are learning how to change their vaccines to deal with virus mutations. Experts are looking to influenza, or flu, vaccines to help them understand if and when the shots may need to be changed. Richard Webby directs a World Health Organization (WHO) flu center from St. Jude Children’s Research Hospital in Virginia. He said that the process will not happen quickly. “It’s not really something you can sort of flip a switch, do overnight,” Webby said. Viruses mutate, or change, often. Recent studies have raised concerns that first-generation COVID-19 vaccines are not as effective against a coronavirus mutation that first appeared in South Africa. However, many of the COVID-19 vaccines are made with new technology that permits changes. But it will still be difficult for experts to decide whether the virus has mutated enough to make it necessary to change the vaccines.
