“I think that extending the fourth dose of the Covid vaccine to other potentially susceptible categories of people may be the right direction. And I am of the opinion that you don’t have to wait for the updated vaccine, because even that in the end will be based on variants that will no longer exist or are no longer there. It’s a partial update, in the end. And I wouldn’t wait. “So Andrea Crisanti, director of the Department of Molecular Medicine at the University of Padua, at time.news Salute.
FOURTH DOSE TO SANITARIANS – “It is right to extend the fourth dose. But for health professionals the obligation” to undergo the second booster “I think it would be a demagogic measure – says Crisanti – The vaccine is a therapy and must be given to those in need. An operator who maybe he took 3 doses, he also got the infection and maybe he has very high antibody titers why do you have to take the fourth dose if you don’t want to do it? “.
The expert reiterates the importance and usefulness of expanding the categories to which the second booster is offered. But marrying “the mandatory fourth dose line” would be “the result of scientific carelessness. Always speaking of health professionals, the fourth dose could be mandatory for those who have to do it, that is, for those who do not have an adequate immune response”.
THE TRANSMISSION OF VIRUS – Crisanti is drastic: “Whoever speaks at this moment of blocking the transmission” of Sars-CoV-2 “does not understand anything about virology or epidemiology, he does not know what he is talking about”. And he explains: “It is impossible not to circulate the Sars-CoV-2 coronavirus today. And it is wrong to prevent it. Because a virus that has a transmission index of 15 does not stop with anything”.
