The study by Iss and Fondazione Bruno Kessler: “On June 30, vaccination allowed the resumption of 50% of social activities compared to the pre-pandemic period: without vaccines to have the same number of cases only a third of the activities would have had to reopen, and there would have been 12 thousand more deaths “

«L’negative effect on infections due to the spread of the Delta variant, more transmissible than the previous ones, in Italy it was practically canceled by the vaccination campaign“. This is the conclusion of a study ofHigher Institute of Health and of Bruno Kessler Foundation published on the MedXriv website. The report was prepared to assess the possible “further easing of social restrictions in relation to the trend of vaccination coverage”.

With a mathematical model, the experts measured the effects of the vaccine in relation to the application of protective measures: masks and spacing.

Here are the results: “Depending on the measures and vaccination coverage, the Rt index of the virus can go from 0.7 (without further easing of the measures compared to those of September 2021 and with coverage close to 100% in all ranges of age over 12 years) to 1.8 (with the total abandonment of the measures * and without increases in coverage compared to those of September 2021) “.

«Our estimate is that, al June 30, 2021, vaccination allowed the resumption of 50% of social activities compared to the pre-pandemic period. In the absence of the vaccine to have the same number of cases, only a third of the businesses would have had to reopen, and there would have been 12 thousand more dead»Between 27 December 2020 and 30 June 2021.

The effect of the diffusion of the Delta variant in July – the scientists write – was “entirely canceled by vaccination” in the period of July and August 2021.

Finally, “an increase in vaccination coverage in all age groups or the availability of a pediatric vaccine will allow further reopening without compromising epidemiological stability”.

In particular, «we estimate that a full return to pre-pandemic life could only be safely achieved if more than 90 percent of the population – including children over the age of 5 – was vaccinated with the mRna preparations’.
