“I am personally convinced” of the opportunity “of the vaccination obligation, because it is a duty that we all have towards the community”. Sergio Abrignani, immunologist of the State University of Milan and member of the Technical Scientific Committee for the Covid-19 emergency, reiterates his position, who spoke at ‘Agorà’ on Rai3. “When I hear that there are 10-11% of people who do not want to be vaccinated and 7-8% who probably will not get vaccinated”, it means that “overall 18% of Italians” will not protect themselves. So “there are 10 million who do not want to be vaccinated – the expert calculates – plus those who for health reasons will not respond to the vaccine, which are about half a million”. With these numbers “we will allow the virus to circulate again and this – he warns – is no small problem”. “We are allowing ourselves all these reopenings because the risk analysis has worked. With the vaccinations behind us, of course, they have done from a central mitigation factor “, Abrignani said later, who shows” the optimism of those who know the data, of those who look at them and who have seen how all that in the last month, month and a half all data are going towards a strong pandemic reduction “. The decisive impact of vaccinations, he stresses, has been” and we knew it “on the basis of” everything that has already happened in Great Britain and Israel. It is no surprise that there is such a reduction strong of the pandemic when we have well exceeded a third of Italians vaccinated “, observes Abrignani. “Obviously – he warns – all this must be monitored”.
