For many of us who have had Covid a few times, you may wonder how some people avoid getting infected.
Some people have even been infected more than three times, and the newest strain is more contagious than ever before.
Labor leader Sir Keir Starmer has been in isolation six times since the start of the pandemic.
But one doctor has explained that people “can definitely get Covid twice”, and that explains why the number of cases here remains high.
Dr. Stout told Belfast Live : “The vast majority of people we see in the daily figures will have had some form of previous infection.
“Keir Starmer is a good example, as what he wants now is almost certainly the Omicron variant, and in the past he could well have had the Delta or Alpha variant.
“One of the difficulties with the variants is that having one of the previous ones does not necessarily protect you from the next one. It has become quite clear since the previous Delta infection we know now has virtually no protection or natural immunity. against Omicron.
“It’s the simplest reason people get Covid twice – it’s down to the different variants.”
While cases of people receiving Covid-19 more than once throughout the pandemic have been reported, concern is growing as immunity declines and new variants emerge.
Dr. Stout added: “That’s why the booster has been so important to Omicron because we have known that the level of immunity given by the first two vaccine doses has started to decline.
“Therefore, the booster provided the extra level of protection, but it actually provided protection beyond that, which then prevents people from getting Omicron or definitely getting seriously ill with it.”
But Dr. Stout said research on reinfections is still in its infancy.
“It’s one of the things we learn over time, and yet there’s quite a lot of data and evidence around what protection people have, which then helps with planning in terms of vaccination.
“One of the big things we do not know is about any next variant. Just as we know there will definitely be more variants, whether we get one more severe or they become less and less severe over time, and evolution is another significant possibility. “
