From the vaccine with adenovirus, such as AstraZeneca, ” there have been serious side effects but they are very few and if we compare them with the side effects of other drugs, such as birth control pills, we see that it is incomparable, that is, there are many fewer ”. This was stated by the extraordinary commissioner for the coronavirus emergency, Francesco Paolo Figliuolo, speaking to Elisir on Rai 3. As for the recalls, ” from the scientific point of view there are studies, even advanced ones, which have yet to find further confirmation, in order to do the second dose so-called ‘heterologous’: that is, do a first dose of AstraZeneca and for some special cases or because maybe at that moment AstraZeneca is not available to do the booster with mRna vaccines such as Moderna, Pfizer or Curevac. And this from the immunological point of view seems to give an excellent answer but certainly I do not allow myself to enter the field of scientists ”, said Figliuolo.
