“The third dose protects. Here’s who is most affected “- Corriere.it

The third dose of the mRNA vaccine reduces the prevalence of Long Covid disease from 42% to 16%. To tell the results of an Italian study published in the journal JAMA. She confirmed that the syndrome affects more women, the elderly and those with chronic diseases

there The third dose of the vaccine mRNA Reduces the spread of Long-Covid.

This is stated in a study just published in the journal JAMA (Journal of the American Medical Association) conducted by the teacher Maria RichinoHead of the Laboratory of Mucosal and Microbial Immunology at Humanitas and Professor of General Pathology at the University of Humanitas, and by Dr. Elena AzuliniDeputy Director of Health at Humanitas, in collaboration with Professor Alberto Mantovani, Scientific Director of Humanitas.

I study

The analysis revealed that the spread Long Covid rose from 41.8% When vaccines were not yet available, 16% by 3 doses of Pfizer administered. “2560 health workers from 8 Humanitas Hospitals in Lombardy and Piedmont (and Humanitas University) were monitored over a two-year period – he explained to courier Maria Richino -. Subjects were tested every one or two weeks for Covid positivity and assessed from March 2020 until April 2022, thus in the pre-vaccination and post-vaccination period. The presence of at least one symptom (such as extreme fatigue, headache, cognitive fog, loss of smell or disturbances in the cardiovascular system) four weeks after the onset of infection is considered to be indicative of Long-Covid disease.”

who hits

The study showed that Vaccination protects against Long-Covid disease, especially after three doses: «The prevalence of Long-Covid disease was of general concern about 30% of people, in line with what has also been described in other studies – described by Rescigno -; However, by analyzing the population participating in the research according to immunization, it was noted that the proportion of Long Covid diagnosed before vaccination was 41.8%, and after the second dose it was reduced to 17%, reaching 16% after the third dose. So the mRNA vaccine protects against Long Covid and this Regardless of the variables Circulating.” It was not exposure to different variants of SARS-CoV-2 that occurred over time that changed the data: “The variants were checked and excluded by our engineers thanks to artificial intelligence that instead highlighted the role of vaccination and some of the risk factors, ‘ said the researcher. Being a woman is associated with diseases with age It is the factors that predispose to the emergence of Long Covid and these characteristics, which appeared in international studies, were also confirmed by the Italian study: “With the increase in comorbidities (including high body mass index and obstructive pulmonary diseases) of Long Covid, especially for those with allergies. But people They are affected even with minor ailments.”

global phenomenon

Long-Covid is a phenomenon destined to increase: it is a syndrome that occurs after Covid infection (severe but also asymptomatic) and accompanies people for weeks or months with persistent symptoms (one or more) which they generally understand Aches and fatigue It can infect the lungs, bronchi, nervous system, kidneys, intestines, heart and blood vessels, as well as the brain with confusion, headaches and so-called “mental fog”. Due to the large number of people infected with SARS-CoV-2, Long Covid, recognized by the World Health Organization (WHO), could become the next Global health emergencyBecause it is estimated that it can infect about 30% of former Covid patients. Hence the importance of determining the degree of protection from vaccination against this syndrome, as the Humanitas study did.

What are the reasons for that

There is still much to understand about the causes of the phenomenon, we direct ourselves to understanding the factors that may be at its origin, as shown in courier In a recent interview with Professor Alberto Mantovani: the general health of the infected, the silent persistence of a virus that can awaken and/or provoke immune reactions and the presence of other viruses that are quiet within us (such as Epstein-Barr virus or cytomegalovirus) that can be reactivated, finally, By unleashing the autoimmune phenomena that SARS-CoV-2 can cause.
The available weapons are few: at the moment the symptoms are treated and the only possible prevention against the problem seems to be vaccination.
