The anti-Covid vaccine not only prevents intensive care units from being crowded with patients to be intubated again, but can also protect against the ailments of the so-called long Covid. Even those who get vaccinated, if they do not follow the precautionary measures, could find themselves a positive swab, but if they are protected by the two doses they will not develop the disease in a serious form and will not even have to deal with the aftermath of Covid. The so-called long Covid is a condition of persistence of symptoms such as fatigue, loss of smell and taste, breathlessness, to name but a few. These are disorders which, as the Istituto Superiore di Sanità (Iss) explains, “can prolong with a heterogeneous complex of subacute and chronic clinical manifestations that preclude a full return to the previous state of health“. It is therefore not a minor problem. ISS experts are also monitoring cases of reinfection to assess whether vaccination prevents the appearance of long Covid. The Italian Society of General Medicine and Primary Care (Simg) is also part of the working group. “We are observing if a vaccinated who falls ill with Covid can theoretically have a prolonged form of Covid – explains the president of Simg Claudio Cricelli – Although, in our opinion, from the observation we have at this time it is unlikely”.

No long Covid for those who are vaccinated
Experts are almost certain: no long Covid for those who are vaccinated. “The prerequisites are all there even if there are not yet solid data to be able to affirm it – explains Roberto Luzzati, Professor of Infectious Diseases of the University of Trieste – We remember that the long Covid in the unvaccinated has a high incidence, between 40 and 50 percent. Vaccinated people, on the other hand, generally do not develop the disease, except in an asymptomatic or mild form, and even less long Covid ». Moreover, the data of the epidemic of these days, with an increase in positives but not in serious cases that require hospitalization, clearly demonstrate this.
“In general, more than 90 percent of people who become infected after the two doses of vaccine – confirms Roberto Giacomelli, director of Clinical Immunology and Rheumatology of the Campus Bio-Medico University Hospital of Rome – have a very mild or even totally asymptomatic form. . So it is practically almost impossible that they can develop a long Covid. In the vast majority of cases, in fact, they do not even notice that they have had the infection ».

In short, the vaccine also avoids illnesses that last for months. «Prophylaxis is extremely important because it protects against the risk of becoming ill with the severe form of the disease – reiterates Giacomelli – We are observing many people who become infected even after two doses. The problem is that they only notice it because they swab. But 99 percent of these people have a totally asymptomatic form ». There is no doubt about the effectiveness of the anti-Covid vaccine. “The healthy immunocompetent subject who responds as 99 percent of a population is protected from the most serious forms of disease including long Covid – remarks Mauro Pistello, full professor of Microbiology and Clinical Microbiology at the University of Pisa and vice president of the Italian Society of Microbiology – In cases where the disease develops the same, it is not a problem of the vaccine, but of the fact that the immune system has not responded in the expected way ».

Experimentation
Some studies are now targeting the vaccine‘s effectiveness in reducing the symptoms of long Covid. That is, if an inoculation, in subjects recovered from the disease but still struggling with long Covid, could be useful. “If the individual’s immune system is unable to shake off the infection – specifies Pistello – an external stimulus is administered against the virus itself. In this way, the immune system strengthens its response. The vaccine could be a good therapeutic option ».
