Eine neue Studie mehrerer Universitäten in den USA kommt zu dem Schluss, dass eine Corona-Reinfektion im Schnitt alle 16 Monate möglich sein könnte. Aber heißt das, dass wir Corona und damit einhergehende Maßnahmen, Beschränkungen und Lockdowns nie überwinden werden? Eine Einschätzung. [swr.de]
People who have been infected with SARS-CoV-2 can expect to become reinfected within one or two years, unless they take precautions such as getting vaccinated and wearing masks. That’s the prediction of modelling based on the genetic relationships between SARS-CoV-2 and other coronaviruses. [Townsend, J. P. et al. Lancet Microbe https://doi.org/10.1016/S2666-5247(21)00219-6 (2021)] […]
To estimate the durability of SARS-CoV-2 immunity, he and his colleagues wanted to understand how antibody levels from a previous infection affect the risk of reinfection. Data from an earlier study allowed the team to chart this effect over years for ‘endemic’, or continually circulating, coronaviruses that cause the common cold. But SARS-CoV-2 is too new for such long-term data to be available. [Edridge, A. W. D. et al. Nature Med. 26, 1691–1693 (2020)] […]
Cobey also underscores the need for people who have been infected to bolster their protection with a vaccine — a point driven home by research published by the US Centers for Disease Control and Prevention in August. The study looked at people who got COVID-19 in 2020, some of whom became reinfected in May or June 2021. It found that those who had not had a vaccine were more than twice as likely to get reinfected in that period as those who had both the virus and a vaccine. [Cavanaugh, A. M., Spicer, K.
