«The anti-COVID-19 vaccination, as happens with all vaccinations, does not protect 100% of vaccinated individuals. We currently know that COVID-19 vaccination protects 88% from infection, 94% from hospitalization, 97% from ICU admission, and 96% from an ICU if the complete vaccination course is carried out. fatal outcome of the disease “.

This was underlined by the Istituto Superiore di Sanità in a new Faq on vaccines published today on its portal. “It is therefore possible and expected – specifies the ISS – a limited number of cases of infection, hospital admissions, intensive care admissions and deaths even among the vaccinated, in an extremely lower number if compared to those who occur among unvaccinated subjects ».

As for the evaluation of the effectiveness of vaccines, “if vaccinations in the population reach high levels of coverage – the Institute warns – the paradoxical effect occurs for which the absolute number of infections, hospitalizations and deaths can be similar among vaccinated to the unvaccinated. In these cases, however, the incidence (understood as the ratio between the number of cases and the population) is about ten times lower in vaccinated than in unvaccinated. These numbers, if read correctly, therefore reaffirm how effective vaccination is ». The surveillance systems, moreover, “do not make evident the cases of disease avoided by vaccination but only reveal those who fall ill despite vaccination”.

Finally, underlines the ISS, «the vaccine, when administered with the entire cycle, is effective in protecting the population. However, it should be remembered that the more the virus circulates, for example, due to a non-optimal vaccination coverage in all age groups and / or for non-compliance with restrictions, the greater the risk that the virus is transmitted to subjects at risk of the disease. severe even if vaccinated and favor the phenomenon of the appearance of new variants ».
