Covid, vaccine protection is protracted over time

We are historical witnesses the importance of vaccines as a public health facility: once again, the data from the Istituto Superiore di Sanità photograph the impact of the vaccination campaign in Italy, with an impressive reduction in new cases, hospitalizations and deaths from covid in every age group. age and an increasingly concrete hope: that of protracted protection over time. The second joint analysis report of the data from the national vaccine registry and integrated COVID-19 surveillance (Istituto Superiore di Sanità and Ministry of Health) refers to approximately 14 million people vaccinated with at least one dose of any vaccine, almost a quarter of the Italian population.

Lives saved. As stated in the document, the risks of covid infection, hospitalization, admission to intensive care and death from SARS-CoV-2 infection decrease rapidly after the first two weeks and up to approximately 35 days after the administration of the first dose of any vaccine. At that point, the reduction stabilizes at levels which we are observing the fruits of these days: minus 80% in the risk of diagnosis, minus 90% risk of hospitalization and admission to intensive care, minus 95% risk of death.

This protection is observable in both men and women, in all age groups, and also in the most at-risk contexts such as hospitals and nursing homes. The analysis confirms the results already found in the previous report, but on larger numbers, which include a greater number of vaccinated in the age group 40 years and over.

Protected for a long time. Unlike the previous report, the latter, which includes data up to May 30, has continued to study the effectiveness of vaccines over time: what emerges from the data is that in the long term, 105-112 days after vaccination, observes a new “step”, a further reduction in the risk of diagnosis, with a similar effect in men, women and people in different age groups. Importantly, there is no increased risk of covid diagnosis in the 130 days following vaccination: the protection offered by vaccines is protracted over time and – given that there is no sign of a decrease in the period under consideration – it could last a long time.
