Imposing the second dose with a vaccine other than AstraZeneca is “risky”, according to Massimo Clementi. In an interview with the agency AdnKronos, the director of the Laboratory of Microbiology and Virology at the San Raffaele hospital in Milan, spoke about the vaccine mix for people who have already received the Anglo-Swedish product as their first dose. “If a vaccinated with AstraZeneca under 60 does not want a booster with an mRna vaccine it could be a problem,” said Clementi. “These people have signed a consent that does not only concern the first dose, but the entire vaccination process. If a person decides to appeal to the TAR because he does not want the heterologous call – he said – he risks winning it ».
“Imposing it is risky from a legal point of view”
“Freedom of choice would therefore be desirable, in my opinion, at the present time,” explained the virologist, who nonetheless underlines the importance of the decision to open up to vaccination by combining two different anti Covid drugs. «Imposing it is risky because the mix is not approved by any authority. The EMA also reiterated a series of conditions: each vaccine is approved for two doses and two doses must be done ». According to Clemente, in particular, the choice of the mix recalls the decision taken by British Prime Minister Boris Johnson when “he gave a single dose of AstraZeneca to as many people as possible to block the wave” that hit the United Kingdom. From that strategy, however, “vaccinated with a single dose remain more susceptible to the Delta variant,” continues the specialist, who reiterates: “A complete vaccination cycle is needed to be adequately protected. A lot of creativity on vaccines would be good to avoid ”. On the question of suspending the use of masks, Clemente remains cautious even though he considers it a push «for tourism and for people to ride with more tranquility. I would wait until July 1st, ”says the expert. «We followed a line of caution and therefore I would wait if we still want to maintain this attitude of hyper prudence. Also because some infections, especially among young people, are still there “.
