Vaccination after infection with Corona? Researchers conclude that one age group has special benefits

Anyone who has already contracted Covid-19 and is healthy again does not need to be vaccinated? Danish researchers have come up with a clear answer.

If you contract the Coronavirus, the body adjusts various defense mechanisms. Among other things, it produces antibodies that make Coronavirus usually harmless. These antibodies remain in the body even after the coronavirus infection has been overcome and thus provide protection in the event of renewed SARS-CoV-2 infection. However, how long the antibodies remain in the bloodstream and in the lymph fluid has not been conclusively clarified. Take some studies for the portal Subatomic particles Describe a fairly stable six-month immune response. She said that since the antibody concentration is still high at this time, the researchers assume that self-protection against coronaviruses will last longer.

But what does that mean for vaccination against Corona?? Do people who survived Corona do not need to be vaccinated during this period because their protection is sufficient? Danish scientists have now dealt with this topic, and the results of their study have been published in the specialized journal The scalpel Published. In their study, they were able to demonstrate that self-protection with antibodies does not last long after infection with corona, especially in one age group.

The research team led by Professor Steen Ethelberg from the Department of Epidemiology and Infectious Disease Prevention at the Statens Serum Institute in Copenhagen based their research on data from 533,381 people who tested Corona during the first wave in early 2020. According to the researchers, a follow-up examination during the second wave of Corona at the end of 2020 showed 2020, that study participants who contracted corona during the first wave were protected by 80 percent from reinfection – for at least six months. However, this natural protection is less apparent in older adults, like this one Spiegel Reported: According to the study, it was only about 47 percent.

According to the study, 2 percent of study participants aged 65 and over got a positive test result for the first time during the second wave of 2020, with 0.88 percent in this age group testing positive again in the second wave after testing positive in the spring. For comparison: 3.3 percent of people aged 65 years and 1 year old tested positive for the first time during the second wave, and 0.65 percent tested positive again in the spring after testing positive. According to study author Steen Ethelberg, that’s a sign of it That the elderly are at increased risk of re-infection after overcoming Corona infection: “Because elderly people also develop severe symptoms often or even die, the result underscores the importance of protecting the elderly during the epidemic.” Vaccination is currently considered the best preventive measure against Covid-19.

For people who have already had a Corona infection, Advises the Standing Vaccination Committee (STIKO) In Germany for one Vaccination no later than six months after surviving the disease: “It can be assumed that people who have recovered from SARS-CoV-2 or Covid-19 infection have at least a temporary degree of protection from the disease. Because of this presumed immunity, to avoid excessive side effects (excessive systemic vaccination reactions) and given the current vaccine shortage, People with a previous infection (confirmed by laboratory diagnosis) should have a single vaccination, according to STIKO, at the earliest 6 months after recovery, taking into account the priorities. ” It remains to be seen what effect the Danish study has on this vaccination recommendation.
