Americans have received countless mixed messages about the effectiveness of COVID-19 vaccines, natural immunity, herd immunity, and virus transmission. Dr. Michael Segal, a neurologist and neuroscientist, wrote a piece for the Wall Street Journal attempting to clear up some misconceptions about how immunity works when it comes to the vaccines and natural immunity.
And he reached a conclusion that should pique the interest of millions of Americans — as well as policymakers: People who have had COVID-19 and recovered should not be required to get the vaccine, because they are less likely to spread the virus than vaccinated people who have never been infected.
What's that now?
Segal began his piece with a question that has been in the minds of many Americans confused by the Centers for Disease Control and Prevention's vacillating guidelines:
"Vaccinated people are supposed to resume wearing masks, lest they contract and spread the virus. Yet unvaccinated people are still strongly urged to get the shots, which are said to be highly effective. How can both these claims be true?"
The truth is "there's more than one kind of immunity," Segal said.
First, he noted, there's "internal immunity," which, according to Segal, "protects the inside of the body, including the lungs" and "occurs by release of antibodies of the Immunoglobulin G type, or IgG, into the blood and production of T-cells."
Vaccine shots "are highly effective" at stimulating this type of immunity, Segal said, which "largely protects vaccinated people from being overwhelmed by the coronavirus, unless they have an immunodeficiency or are exposed to an unusually large amount of the virus."
