Always on the vaccine mix and second dose with Pfizer or Moderna after the first dose of AstraZeneca. “At this moment it is right to hear many voices but the duty of those who represent the institutions is to give correct information, on 9 June Aifa expressed an opinion on heterologous vaccination based on the studies that are emerging, and there are studies in the United Kingdom, France, Germany. They all demonstrate things we knew: two different vaccines stimulate the immune system better “said the president of Aifa, Giorgio Palù, guest of ‘Che giorno è’ on Rai Radio 1.
On the issue of variant risk, “I recall that mRna vaccines have demonstrated efficacy in inducing neutralizing antibodies also against variants. Two-dose vaccination protects against severe Covid-19 and in Israel, where they have massively vaccinated with Pfizer, it has been shown that it protects against contagion. It is true that these antibodies lose some effectiveness, but at a dilution greater than 1.40 they protect and neutralize the variants “recalled Palù.
“So it is important to vaccinate everyone and also cover adolescents – added the president of Aifa, answering the questions – The possibility of getting infected with the variants is there, but vaccination protects against serious illness”.
