“Two different vaccines better stimulate the immune system”

The combination of the vaccine and the second dose of Pfizer or Moderna should always be used 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 the right information, on June 9 Aifa expressed her opinion on heterogeneous vaccination based on the studies that show, there are studies in the UK, France, Germany, all of them They prove things we knew: Two different vaccines better stimulate the immune system,” said Aifa President Giorgio Palo, guest of “Che giorno è” on Rai Radio 1.

On the issue of variable risk, “I mention that mRna vaccines have been shown to be effective in stimulating neutralizing antibodies also against variants. Two-dose vaccination also protects against severe Covid-19 and in Israel, where they were heavily vaccinated with Pfizer, this has been shown to protect against Infection. It is true that these antibodies lose some efficacy, but at a dilution of more than 1.40 they protect and neutralize the variants,” Palù recalls.

“It is therefore important to vaccinate everyone as well as cover adolescents – the head of Aifa added, answering questions – the possibility of contracting variants is present, but vaccination protects against serious diseases.”
