Do you need the vaccine if you have already had Covid? | India News

NEW DELHI: The Union Ministry of Health has stated in its guidelines that those who have recovered from Covid-19 should also be vaccinated. For those infected at the time of immunization, the appraisal has asked them to postpone the shot for 14 days.
But considering that those who have recovered from the disease would have developed natural immunity to the coronavirus, does it make sense to include them in the vaccination program? Yes, experts say, as there is still no clarity about how long natural immunity lasts or how strong it is.
It is currently believed that antibody levels begin to decline after a few months – think of asymptomatic and milder cases – and people eventually become susceptible to the virus a second time (usually up to three to four months after the first).
Although more research is needed, health experts suggest that people with a recent Covid infection may be able to wait a few months before receiving the vaccine. However, those who have been recovering from Covid for several months should plan to get the shot as soon as it becomes available to them.
Onyema Ogbuagu, an infectious disease doctor at Yale Medicine who tested the Pfizer vaccine, told Huffpost he would recommend the vaccine to someone who had Covid three to four months (or more) ago, especially if it was a milder case acted. There is evidence to suggest that those who take it more seriously may come up with more permanent protection that can last for several months.
Researchers currently suspect that the immunity conferred by the vaccine is more robust than the immunity obtained by natural diseases. But the theory is still being tested. And regardless of whether you’ve had a light fall or a bad case, you’ll want to get the shot at some point.
Ogbuaga says clinical trials of vaccines only recently focused on participants who had Covid to learn more about the body’s response to vaccinations that had already had an immune response.
One theory is that the vaccine could raise antibody levels in people who are already infected and act essentially like a booster shot. However, there is also the possibility that vaccination, in addition to natural immunity, could result in a severe reaction in certain people.
Some doctors have also toyed with the idea of ​​doing antibody tests to see if someone has natural immunity before giving the vaccine. In theory, a neutralizing antibody test would identify people with no immunity who could be prioritized for vaccination so we can achieve herd immunity more quickly.
