“Most of the” covid “cases reported in Italy were identified in the last 14 days in subjects not fully vaccinated (ie who did not receive any vaccine dose, who were vaccinated with the first dose or with the single-dose vaccine by 14 days from the diagnosis itself, ie before the time necessary to develop a complete immune response to the vaccine) “. This is underlined by the Higher Institute of Health in its latest updated report on the epidemic. In the 80+ age group, in the last 30 days, 36% of diagnoses, 50% of hospitalizations, 81% of ICU admissions and 66% of deaths occurred in people who did not receive any dose of vaccine and which are currently 9.5% of the population in this age group “, highlights the ISS. The graphs of the Italian population tell us that” the percentage of cases among vaccinated is much lower than the percentage of cases among the unvaccinated. If vaccines were not effective in reducing the risk of infection, there would be no differences in the number of cases between vaccinated and unvaccinated “, the authors note. period from 04 April (approximately the date on which the vaccination was extended to the general population) to 11 July by age group “, which are proof of the higher efficacy of the two doses. Well, the ISS estimates,” The overall efficacy of vaccination, adjusted for age, is greater than 70% in preventing infection in vaccinated with incomplete course and greater than 88% for vaccinated with full course. The effectiveness in preventing hospitalization “rises to 80.8% with an incomplete cycle and 94.6% with a full cycle. The effectiveness in preventing admissions to intensive care is 88.1% with an incomplete cycle and 97, 3% with full cycle “. Finally, in preventing death it is 79% with an incomplete cycle and 95.8% with a full cycle. These estimates are not adjusted for several factors that could affect it, it is pointed out. But they are indicative of what has already emerged from various publications. As for the type of affected subjects, notes the ISS, “in the last two weeks, 26.7% of total cases are under the age of 19”, therefore more of 1 in 4, “62.3% are between the ages of 20 and 59 and 11% are over the age of 60”. “Most of the reported cases are acquired locally but since June 2021 there has been a slight increase, in percentage, of imported cases”, reports the ISS. And this is also confirmed by the data recorded in the last week: in particular “in 74.2% of diagnosed cases an autochthonous transmission of the infection is reported, down compared to the previous week (76%); in 5.2% cases they come from a foreign country and 1.1% from another region or autonomous province (in 19.5% of cases the information is not known) “.
