The U.S. Centers for Disease Control and Prevention (CDC) has published studies on immunity to COVID-19 after vaccination and disease. As it turned out?
COVID-19 resistance – what does the research say?
Vaccination has been shown to provide stronger immunity against COVID-19 than a previous infection, although in both cases it usually lasts for at least six months, the Washington Post reported.
The newspaper featured two articles published by the CDC. The first is a study of hospitalized patients with symptoms similar to COVID-19. It showed that unvaccinated people who had previously been infected with coronavirus were five times more likely to be sick than vaccinated people.

The second is a summary that takes into account more than 90 studies to date and previously unpublished data from the CDC itself. The researchers note that the results show that vaccination produces a “higher, stronger and more stable level of immunity in protecting people from COVID-19 than the infection itself”. The authors indicate that this is due to, inter alia, from the fact that the level of antibodies in people after an infection has been eradicated is much more variable than in the case of vaccines. In both cases, the data show that immunity is generally maintained for at least six months.
Experts also assessed that there is currently no test that can be used to reliably assess the degree of immunity in a person.
This research is important in the context of the debate that is taking place, among others in Congress. For example, some experts want to treat a past infection as one dose of vaccine. Such rules are in force in many countries, incl. in Europe, but not in the US.
