An expert describes those who are not immunized against Corona “possible factories for virus variants”

Dr. William Schaffner, a professor in the Department of Infectious Diseases at Vanderbilt University Medical Center, described unvaccinated people as 'potential manufacturers of variants'.

"The more unvaccinated people there are, the greater the chances of the virus multiplying," Schaffner told CNN.

When that happens, the virus mutates and could cause a more serious mutation in the future, Schaffner said.

He added that all viruses are subject to mutation, and although the Corona virus is not particularly susceptible to producing mutations, it does change and evolve.

Most mutations mean nothing to the virus, and some can weaken it, but sometimes the virus develops a random mutation that gives it an advantage such as better transmissibility, for example, or more efficient reproduction, or the ability to infect a large variety of hosts, according to Schaffner. .

He added, viruses that have an advantage over other viruses will eventually make up the majority of virus particles that infect a person, and if that infected person transmits the virus to another person, he will transmit the mutated version.

If the mutated version is successful enough, it turns into a variant, but it must reincarnate to do so, and the unvaccinated person provides that opportunity and viruses that do not spread cannot mutate, he says.

Infectious disease specialists said that people who are not immune to corona pose a danger to everyone if they contract the virus.

This is due to the fact that the only source of variants of the emerging corona virus is the body of an infected person, according to specialists.

Variants originated all over the world and the "B.1.1.7" or "alpha" variant first appeared in England.

The variant "B.1.351" or "beta" was detected for the first time in South Africa.

The "delta" variant, also known as "B.1.617.2", first appeared in India.
