People who have previously been infected with the virus that causes COVID-19 are protected against being infected again and thus don’t need to be vaccinated, according to a new study.
“Our conclusion is that if you were previously infected, you are protected because of the previous infection and you don’t need the vaccine,” Dr. Nabin Shrestha, of the Cleveland Clinic’s Department of Infectious Disease, told The Epoch Times.
“Among the people who were previously infected, whether they took the vaccine or not, there really were no COVID cases,” Shrestha said.
Of the 52,238 employees studied, 2,579 were previously infected. About half of those remained unvaccinated. Of the 49,659 employees who did not have a previous infection, 41 percent did not get a vaccine.
Using a Cox proportional hazards regression model and adjusting for the phase of the pandemic, vaccination was linked to a significantly lower risk of infection among those not previously infected but not among those who had had the disease.
In conclusion, the authors wrote, “Individuals who had had SARS-CoV-2 infection are unlikely to benefit from COVID-19 vaccination, and vaccines can be safely prioritized to those who have not been infected before.”
SARS-CoV-2 is another name for the CCP virus.
The study is not peer-reviewed. It was submitted to journals, but they rejected it “because they think it’s not a priority for them,” Shrestha said. But it adds to the growing body of research that supports natural immunity existing for some time among those who contracted the illness.
Based on what the Cleveland Clinic researchers found, natural protection from infection lasts at least a year.
The CDC declined to respond to the new study.
“We do not comment on non-CDC authored papers. We continually evaluate the science that leads to our guidance, and if it needs to be changed, we will be base that on our own research and studies,” a spokesman told The Epoch Times in an email.
Shrestha, the study’s lead author, believes recommending vaccination for previously infected people is misguided.
“I personally feel that the vaccines are amazingly effective. We need to use them wisely. We should really not be thinking of this as a U.S. problem; it is a global problem,” he said. “It would make more sense to use the vaccine anywhere in the world where it would be effective in getting the pandemic under control.”
