In Italian intensive care the majority of the hospitalized, “95%”, are not vaccinated. But “the novelty now is that fragile vaccinates are starting to grow, who were immunized at the beginning of the vaccination campaign, in which a decline in antibody protection is presumed “. And who are put at risk” by the circulation of the virus favored by those who have not undergone the vaccine “. for Adnkronos Salute, he is Antonino Giarratano, new president of the Italian Society of Anesthesia, Analgesia, Resuscitation and Intensive Care (Siaarti).
“Until a few weeks ago – explains Giarratano – in our wards they were almost all unvaccinated, with 5% of fragile vaccinations. In the last two weeks, in various areas of the country, the data of our Siaarti monitoring system have grown fragile vaccinated, with regional differences ranging from 5 to 15% we also begin to see ‘frail less fragile’, that is, no longer the diabetic, decompensated, with lung problems and the elderly, whose balance is particularly precarious. Now we also see patients who do not have severe concomitant pathologies in the strict sense, we are talking about the very obese or severe hypertensive, with an age from 48 to 59 years. Patients who have only one of these problems “.
To avoid vulnerable people, despite double vaccination, going into hospitalizations, explains Giarratano, it is necessary “to vaccinate a percentage of more than 90% of the population. And it needs to be done on two fronts: with the first dose, for those who are not never vaccinated to avoid the circulation of the virus, and with the third dose for the frail, even with only one pathology at risk, who were vaccinated 9-10 months ago, in order to increase the immune response capacity and prevent them from arriving in our intensive care as it is happening “.
GREEN PASS
“Bringing the duration of the Green pass to 9 months is useful. It is now documented by the most recent published studies that the antibody response drops after a period of time. And therefore the risk of vulnerable people becoming ill increases. We already find this in our intensive care units where we have an increase in fragile patients “.” The choice of the duration of the green certificate – continues Giarratano – is more political than technical. But scientific indications can guide us. The only two studies we have tell us that after 6 months the antibody capacity to react to the virus is reduced by 60%. In any case, we must always keep in mind that we still do not know everything about how immunity against this virus works. We acquire more and more knowledge but we don’t know everything “.
“Personally – he concludes – I took the third dose but, at the moment, I don’t know if it will cover me. It could give me an immunity of six months or two years. We don’t know. We have the objective clinical data of the loss of ability to protect from contagion, not from serious illness, after 6-9 months, and therefore it is advisable to take the third dose, especially for the frail, otherwise we fill up the intensive care units again “.
