Dr William Schaffner, professor in the Division of Infectious Diseases at Vanderbilt University Medical Center, told CNN : "Unvaccinated people are potential variant factories.

"When it does, it mutates, and it could throw off a variant mutation that is even more serious down the road." He said that by July next year, 70 per cent of people in every country will need to be vaccinated.
