In subjects not vaccinated against Covid, mortality is 25 times higher than in those who had the booster dose. A figure that emerges from the "Extended Report on Surveillance, Impact of Infections and Vaccination Effectiveness" drawn up by the Higher Institute of Health from which it is also found that, again in the unvaccinated compared to those who have had the third dose, the rate of hospitalizations in ordinary wards is 10 times higher and is 27 times higher than that of hospitalizations in intensive care.
The booster dose, it is explained, protects 95% from severe forms of the disease and 67% from contagion compared to what happens in the unvaccinated. Furthermore, the efficacy of the vaccine, understood as "percentage reduction of the risk in vaccinated compared to non-vaccinated" in preventing severe disease, is 90% in vaccinated with a full course (2 doses) for less than 90 days, 91% in those who have had the 2 doses of 91 and 120 days, and 85% in those who have had it for over 120 days.
The effectiveness of the vaccine in preventing the diagnosis of SarsCoV2 infection, adds the ISS, is equal to 63% within 90 days of the completion of the vaccination cycle, 51% between 91 and 120 days, 40% beyond 120 days from second dose, and 67% in those who had the third dose.
