Covid Italy, there is contagion among the unvaccinated: 10 times more than those who have the third dose

The infection from Sars-Cov-2 runs faster among the unvaccinated, with an incidence rate equal to 237.95 new cases per 100,000 inhabitants, or about 10 times more than the population vaccinated with the third dose. This is the data detected by the 77th episode of the Instant Report Covid-19, an initiative of the High School of Economics and Management of Health Systems of the Catholic University for a systematic comparison of the trend in the spread of Sars-Cov-2 at a national level . Read also In particular, during the period from 29 October to 28 November – explains the Report – infections in the population vaccinated with the third dose stop at 25.03 per 100,000 inhabitants per week, followed by the vaccinated population within 5 months with more than double the number of new cases, in fact the incidence of infections among these people is 61.06 per 100,000 inhabitants per week. The decrease in the effectiveness of the vaccine due to the time elapsed since the last dose – the report continues – leads to a significant increase in weekly infections in the vaccinated population over 5 months, with an incidence of infections that skyrockets to 90.04 per 100,000 inhabitants per these people. THIRD DOSE – “67% of those vaccinated for over 5 months against Covid would not be infected if they had been vaccinated with a third dose. And this would have allowed a reduction in the total number of infections equal to about 29,319 out of 44,023 infections that occurred in the last 30 days “says Americo Cicchetti, director of the High School of Economics and Management of Health Systems at the Catholic University. In the report” to provide a complete picture of the impact of the Covid-19 emergency for the NHS, an estimate was drawn up the number of avoidable infections compared to the third dose vaccination campaign “. To calculate it, the starting point was the data provided by the Bulletin on the epidemiological surveillance of the weekly Covid-19 of the Higher Institute of Health, “in which the absolute number and percentage of vaccinated people in the general population and cases of infection are specified from Sars-Cov2 for vaccination status in the last 30 days “. From here “the two incidence rates in the cohorts were calculated (vaccinated over 5 months and vaccinated with the third dose)”. From the difference between these two incidences, “it is possible to estimate the number of avoidable infections if all the population eligible for the third dose was vaccinated, “according to Altems researchers. 4 DIFFERENT PANDEMICS – The different degrees of vaccination against Covid are creating four different contemporary pandemics, notes Cicchetti. “By evaluating the weekly incidence per 100 thousand inhabitants, calculated by keeping separate the unvaccinated population, the one vaccinated within 5 months, vaccinated for more than 5 months and vaccinated with a third dose, it is possible to see that we are facing four different pandemics that run together ” he claims.
