“We have to look at the fact that we in Italy have been rigid with the second Pfizer dose taken at most 42 days from the first and this, as the study on ‘Lancet’ has shown, gives a shot of antibodies such that the vaccine covers all variants. Let’s rest assured, they are vaccines that work very well even against the variants that have come up in the last period. Four months ago there were those who said that they would not work, but no. Let’s give even more strength to these vaccines that are the answer to the pandemic: they were produced a year ago and still work great. ” Matteo Bassetti, director of the Infectious Diseases Clinic of the San Martino hospital in Genoa, underlines this to Adnkronos Health, commenting on the study on Lancet which highlighted how two doses of Pfizer / BioNTech’s anti-Covid vaccine induce antibodies that neutralize all variants of Sars-CoV-2, while only one is not. “In Great Britain – recalls Bassetti – where at the moment there is an increase in cases linked to the spread of the Indian variant, the effect of vaccine coverage may have been limited by having chosen to give everyone a single dose and many infections could have occurred between the first dose and the recall. But in our country we must rest assured “.
