The UK risks becoming a “melting pot” for the emergence of new and potentially more dangerous coronavirus variants unless the population respects restrictions put in place to limit transmission, scientists have warned.
Health authorities said this week that three different variants of the virus circulating in England had a mutation called E484K, which is believed to undermine the immune protection provided by prior infection and current vaccines.

Concerns about possible resistance to the first generation of vaccines lies behind Public Health England’s urgent efforts to track people infected with a variant, known as 501. V2, which is thought to have originated in South Africa and carries the E484K mutation.
