All of them met at least one of a total of eight risk factors, as a study now shows. Researchers from the US National Institutes of Health have investigated why some people suffer a severe course of Covid 19 despite full vaccination. For their study, they analyzed the data of around 1.2 million corona patients who were older than 18 years and who received an mRNA vaccine twice or a vector vaccine between December 2020 and October 2021 – before the omicron wave had been vaccinated by Johnson & Johnson. The result: serious illnesses only rarely occurred in the subjects. Of the 1.2 million vaccinated people, 2,246 (0.18 percent) contracted Covid-19 despite immunization. 189 patients (0.015 percent) had a severe course with acute respiratory failure, non-invasive ventilation or admission to an intensive care unit. 36 of them died, which corresponds to 0.0033 percent of the total study participants examined. also read
Eight risk factors for the severe corona course
Using the data, the researchers were able to identify eight factors that increase the risk of a severe course of the disease despite vaccination:
According to the scientists, at least one of these risk factors was present in all people with a severe course of the disease. 78 percent of the patients who died suffered from at least four of these risks.

In their study, the researchers emphasize how effective the vaccination is against a severe course of the disease. They also point out that a booster vaccination is particularly important for risk groups.
