The fact that some EU countries with high vaccination rates have hospitalized many fully vaccinated covid patients is explained by the combined effect of increasing vaccination rates, given that vaccines provide high, but not total, protection from the disease. serious, and of the “degradation” over time of the immunity given by the vaccine. To explain what is known as the paradox effect is the ECDC, in the Risk Assessment published today.
Given that vaccines offer “high” protection from the “severe” outcomes of Covid-19, a “large number” of hospital admissions caused by the disease will affect “unvaccinated individuals, particularly those in risk brackets”. However, the experts of the EU agency explain, “given that the effectiveness of the vaccine against serious disease is not 100%, the increase in positives will also lead to an increasing number of vaccinated people who develop a severe form of the disease, which requires hospitalization “.
Together with the “degradation of immunity given by vaccination over time, this explains the proportion of vaccinated individuals among Covid patients hospitalized in some countries with high vaccination rates”. In practice, if vaccination rates increase, it is obvious that the hospitalizations of the vaccinated also increase, because they are the majority of the population: since the protection is not total, the absolute number of those for whom the vaccine ‘does not work’ grows , as the population gets vaccinated, while remaining significantly lower than the number of those for whom, instead, the protection given by the vaccine works.
