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

He explained that "The more unvaccinated people there are, the more opportunities for the virus to multiply." He continued saying "When it does, it mutates, and it could throw off a variant mutation that is even more serious down the road."

According to Schaffner, most changes are insignificant and some even weaken the virus, but sometimes a virus develops a mutation that gives it an advantage, such as better transmissibility, more efficient replication or an ability to infect a wider diversity of hosts.

A microbiologist and immunologist at the Johns Hopkins Bloomberg School of Public Health Andrew Pekosz told CNN "As mutations come up in viruses, the ones that persist are the ones that make it easier for the virus to spread in the population." 

"Every time the virus changes, that gives the virus a different platform to add more mutations. Now we have viruses that spread more efficiently," he added.

According to the World Health Organization (WHO), "The more we allow the virus to spread, the more opportunity the virus has to change."
