Few elements have been leaked so far regarding the results of the study conducted between Padua and London. One above all, however, would provide a positive answer for the development of future therapies and strategies in the fight against Covid 19: the natural antibodies to the coronavirus persist for at least 9-10 months. This is not the only positive result of the test on the population of Vo: those of the healed of the first wave who were directly exposed during the second wave to Covid-19 did not get sick again. The survey involved 125 residents in Vo "Euganeo and fractions (88 swab positive in February 2020, the other positive serological test results during May checks).
led by the team of researchers at Mount Sinai hospital in New York, most of the cotagiates who had a mild or moderate form of Covid-19 showed a strong neutralizing antibody response for at least five months. A study by the King's College of London, on the other hand, found that immunity drops quite quickly within three months, especially among the elderly and asymptomatic. Most of the studies carried out on immunity from Covid-19, however, reveal that protection of neutralizing antibodies can last on average between 6-8 months.
of the population of Vo ", will be published in Nature in about a month and a half, after the favorable opinion of the scientific committee of the journal that will have validated all the elements of the test. Some important data have already emerged, namely that the antibodies produced by the coronavirus remain circulating in Covid positive people from 9 to 10 months. Furthermore, when people with antibodies encounter a positive, the antibodies reactivate, providing a new barrier of protection. The study on Vo "involved the vast majority of the over 3,200 citizens who on several occasions they underwent the swab and serological analysis.
The second test on the Immunity to Vò Euganeo
The population of Vò Euganeo has been subjected to tests and studies on several occasions. In the research conducted by Professor Crisanti, a significant fact emerges: who among the subjects healed in the first wave was exposed directly during the second wave - because living with or in contact with a person who contracted Covid 19 - did not get sick again. The "survey in this" second round "involved 125 residents of Vo" Euganeo and fractions (88 swab positive in February 2020, the other positive serological test results during May checks).
What emerged from the further screening of the reduced sample of subjects is that the antibodies, mostly neutralizing, remain in circulation for up to 10 months, without substantial differences in the antibody titer between symptomatic and asymptomatic and not even between different ages.
The study therefore seems to reveal that there is a sort of rather lasting protective umbrella for those who have encountered coronaviru, even for those who have been totally asymptomatic (and therefore positive for serological).
Useful results for vaccines
This will have important implications for understanding the biology of the virus, and for vaccine development, also for assessing the long-term consequences of the pandemic.
The side effects of vaccination are minimal and do not preclude the possibility of doing sports immediately afterwards.
