Researchers who sent home fingerprint tests to more than 365,000 randomly selected people in the UK found a more than 26% drop in antibody Covid-19 in just three months.
“We observed a decline in the proportion of immune populations detected during the three rounds of national surveillance, using self-flow tests later, 12, 18 and 24 weeks after the first peak infection in the UK,” the team wrote in a pre-release release from their pre-release report.
“This is consistent with evidence that seasonal immunodeficiency declines in the 6 to 12 months after infection and data emerging in SARS-CoV-2 that also detect a periodic decline in immune levels in individuals following long-term studies,”
The study was published Monday by Imperial College London and Ipsos MORI, a market research firm. They reported that at the start of the study, in June, 6% of those tested had an IgG immune response to coronavirus. As of September, only 4.4% of them had done so. For health workers, the rate remains the same.
The results also confirmed previous studies showing that people without the symptoms of Covid-19 were more likely to lose their immune system sooner than people with more severe infections.
The researchers found that people who were cured of Covid-19 had a slower immune system loss, compared with people under the age of 75 who survived the infection.
Some infections, such as measles, cause what is known as the immune system. People who are once infected have immunity that can be detected many years after infection.
Education has limitations. Samples are not taken from the same person over and over again, but from different people over time. Researchers say it is possible that people who have been exposed to coronavirus have a slim chance of spending time and may be distracted by the numbers.
“We do not yet know if this will put these people at risk for the virus that causes COVID-19, but it is imperative that everyone continue to follow the guidelines to reduce the risk to themselves and others,” said Ward.
The British Minister of Health, Lord James Bethell, called the study “significant research” that could help inform the British government on the right course of action to control the spread of Covid-19.
“It’s also important for everyone to know what it means for how they – this study will help to fight the virus of us, but tested positive for antibodies does not mean that you are immune to Covid-19,” “whether as a result of testing immunity, must continue to follow the guidelines of the government, including distant social isolation of the self test and if you have and remember the hands, face and space.”
Dr. Claudia Hoyen, a pediatric infectious disease specialist at the University Hospital, thinks the study is interesting and encouraging, because it indicates that, in the case of immunodeficiency, the disease reacts like any other coronavirus. Like the common cold, the immune system is weakened and people can catch a cold more than once. As with colds, people with strong immune systems, young people, do not usually see a weakened immune system as quickly as people with older immune systems.
“This study is similar to the first shutdown that showed us that, yes, these immune systems do not seem to be attached to everyone,” Hoyen said. “In this case, the virus is acting in a way that we can predict, which is good in this case.” Hoyen says the study also mentions the fact that we will have scars in half.
“I know we all hope this will end soon, but I do not think it will be possible,” she said.
“I think we will soon fix ourselves because this is what we need to do to get through this, we can accept it and move on. This information clearly shows that your immune system is gone, does not make you immune and it means you can contact again.”
