Burioni and the Pfizer case: “On vaccine protection objective data, that’s enough”

“In the phase 3 studies, the” Covid “vaccines were not evaluated for their ability to hinder the infection, because this would have taken a long time and delayed the marketing of a vaccine that, first of all, had to avoid serious disease “. However, “subsequent observations clearly demonstrated the vaccine’s ability to prevent infection and the spread of contagion.” So on Twitter the virologist Roberto Burioni, lecturer at the Vita-Salute San Raffaele University in Milan, even after the debate aroused by Pfizer representatives who – during a hearing in the European parliament – explained how the experimentation on the Covid vaccine was conducted -19. With regard to the “subsequent observations”, Burioni refers to a post of 10 October in which he explained that “vaccination, from Omicron (January ’22) onwards, no longer completely protects against infection, but before that the protection was very high : in April 2021 two doses protected 92% from infection and therefore the vaccine was then also essential to hinder the spread of the virus “. The scientist comments today: “These objective data will not silence the poisoners of wells, but I have done my duty. Now that’s enough”.
