Almost 99 deaths from Covid 19 out of 100 since last February had not completed the vaccination cycle, and among those who had completed it there is a higher average age and an average number of major previous diseases than the average. This is what emerges from an in-depth analysis contained in the periodic report on the deaths of the Higher Institute of Health.
Up to 21 July, 423 deaths from Covid were vaccinated with full cycle and represent 1.2% of all Sars-CoV-2 positive deaths that occurred since last February 1 (a total of 35,776 deaths), chosen as the index date because it corresponds to the 5 weeks necessary for the completion of the vaccination cycle starting from the start of the immunization campaign.
The analysis is based on a sample of 70 medical records of 423 Sars-CoV-2 positive deaths that occurred up to 21 July 2021 in vaccinated people with a complete vaccination course (16.5%).
Compared to the totality of deaths for which medical records were analyzed – reports the ISS – in the sample of deceased with a complete vaccination cycle the average age is decidedly high (88.6 vs. 80 years). Furthermore, the mean number of pathologies observed in this group of deaths is 5.0 (median 5, standard deviation 2.2), much higher than deaths in the general population. After acute respiratory failure, superinfections are the most common complications in people who have died with a full vaccination course. Antibiotic and steroid therapy are the most used therapies on these patients.
“The results presented here – reads the report – may have two possible explanations. First of all, very elderly patients with numerous pathologies may have a reduced immune response and therefore be susceptible to Sars-CoV-2 infection and its complications despite having been vaccinated. In secundis, this result can be explained by the fact that older and vulnerable people have been given priority for vaccination and that therefore this represents the population with the highest prevalence of full-cycle vaccination at the date of this evaluation was carried out “.
