Up until now, scientists and medical professionals are uncertain as to how long protection from a natural infection or vaccine immunity lasts.
Dr. William Schaffner, professor of preventive medicine and infectious diseases at Vanderbilt University Medical Center told Healthline, “There are some people who have the notion that after you’ve gotten a natural infection, you will be permanently protected against COVID-19 as if this were measles. But the two viruses that cause these infections are very, very different. The coronavirus protection wanes naturally after a period of time.”
“We all know we can get repeated common colds, and the studies on those viruses indicate that their protection begins to wane after about a year, and of course we can get new infections down the road,” he added.
Since the onset of coronavirus, different research has disclosed different data. While an October 2021 study reveals that for people who recover from COVID-19, immunity could last for about 3 months to 5 years, another study found that immunity can last for as long as 8 months.
However, experts have said that more research is needed to confirm the same.
