Mortality among those who are not vaccinated is 15 times higher than that of those who received the booster. The weekly data from the Higher Institute of Health have come out which account, among other things, of vaccination efficacy. The numbers confirm the third dose gives a high protection against severe forms of the disease and instead manages to avoid infection with a little less effectiveness.
Covid vaccines, fourth dose but not for everyone: questions and answers
by Elena Dusi
The rate of ICU admissions for non-vaccinated people over 12 is about 13 times higher than for vaccinated with boosters and 4 times higher for vaccinated with a full course of less than 120 days. Regarding hospitalization in general, the rate is 8 times higher in unvaccinated over vaccinated with boosters.
Third dose 92% effective
As regards the prevention of severe disease cases, “the efficacy of anti-Covid vaccines is equal to 73% in vaccinated with a full course of less than 90 days, 76% in vaccinated with a full course of 91 and 120 days, and 76% in the vaccinated who have completed the vaccination cycle for over 120 days. It rises to 92% in those vaccinated with an additional dose / booster “, explain from the Institute.
26% of the positives are under the age of 20
For the third week, the percentage of cases reported in school age fell, accounting for 26% of the total. If we only look at people from 0 to 19 years, in the last week 15% of cases were in children under 5 years, 39% in the 5-11 year range, 46% in the 12-19 year old. On a general level, on the incidence front, the highest rate at 14 days is recorded in the 10-19 year range, 1,695 per 100,000 inhabitants, while between 70-79 years old the lowest value, 556 cases per 100,000 inhabitants. The incidence at 14 days is increasing in the 10-19, 20-29, 50-59, 60-69 and 70-79 age groups.
Reinfections
The percentage of reinfection risk is stable. In the last week it was 3.2% of reported cases (last week it was 3.3%). “Analysis of the risk of reinfection from 6 December 2021, when the Omicron variant began to spread, shows an increased adjusted relative risk of reinfection.” In particular, subjects with the first diagnosis of Covid-19 notified for more than 210 days are at risk compared to those who had the first diagnosis between 90 and 210 days previously.
Unvaccinated or vaccinated individuals with at least one dose for over 120 days are more likely than those vaccinated with at least one dose within 120 days; females compared to males, probably due to the greater presence of women in the school environment where an intense screening activity is carried out and for the role of caregiver in the family environment; age groups younger than people with the first diagnosis between the ages of 50-59. “Probably the greater risk of reinfection in the younger age groups is attributable to higher risk behaviors and exposures, compared to the over 60 age groups”, explain the Institute.
