Do you need to receive a Covid-19 vaccination if you have already had the new Coronavirus before and recovered? Or will receiving vaccination be limited to people who have not been infected with the Coronavirus?
|The answer is: We don’t know yet, and there is an ongoing debate.|
So far, vaccine trials have focused on people who have not been exposed to the Coronavirus, so the effect of vaccination on people who have been exposed to it is unclear, according to a report by the British newspaper The Guardian.
However, given that immunity to the Coronavirus wanes over time, it is likely that it will be worth getting vaccinated. Professor Robin Shattuck, Head of the Department of Mucosal Infection and Immunology at Imperial College London, says, “The level of immunity from natural infection is variable, so some people get a robust immune response, and some people have a feeble immune response. The vaccine will enhance your immune response, and we hope that Provides longer protection.”

Even after people are vaccinated, they may need additional booster doses to keep their immunity high.
Dr. Moncef Slaoui, scientific head of Operation Warp Speed - a public and private government partnership to facilitate the development and manufacture of the Covid 19 vaccine – says that in the experiments on the vaccine, people were recruited on the basis that they did not have COVID-19 clinically, but it turned out that what between 5 and 10% of people who have been recruited are likely to be infected with the disease without symptoms or mild symptoms too did not notice it, according to the site, Newsweek.
Slaoui explained that what we know is that vaccines are safe in this group, and vast numbers of them have been immunized, and their immune responses are analyzed.
Dr. Mark Seidner, an infectious disease physician and clinical epidemiologist at Massachusetts General Hospital, says that there is not enough evidence to know whether vaccination benefits those with previous infections.
“On the one hand, we know that some people, especially those with weakened immune systems, remain at risk of re-infection,” Seidner told Newsweek, “but on the other hand, recurrence appears to be a scarce phenomenon.”
As for Dr. David Thomas, professor of medicine and director of the infectious diseases department at Johns Hopkins University School of Medicine, he said in a statement to NBC News, “The general recommendation is to get the vaccine even if you have been infected before,” adding that “There are some subtle questions that we do not have an answer to yet, but from what we know now, it is the right thing to do.”
It is believed that re-infection with Covid-19 is rare, but if normal antibody levels diminish over time, a person may be infected more than once. That is why some doctors and infectious disease experts argue that most people should be vaccinated even if they have normal protective immunity.
