“In autumn, the climate is less mild and you are more inland, there is an increased risk” of covid infections. “Proximity and proximity increase the possibility of transmission. It is clear that if we are 80-90% vaccinated the risk is very low, so the vaccination campaign must be accelerated”. This is the prediction of Walter Ricciardi, full professor of Hygiene and Preventive Medicine at the Catholic University of the Sacred Heart of Rome, on the sidelines of the presentation of the results obtained by the new Pchs sanitation system. “Basically we are doing well, what has been done in the last 2-3 weeks in Italy, with reasoned risk, has worked and has led to good results. But we must be vigilant and be careful”, highlights Ricciardi. “I have seen scenes in restaurants that are a bit worrying – he observes -, safety distances are not maintained. Fortunately at this moment you can only be outside, but if this occurs inside with a contagious and a variant, it becomes a very worrying and risky situation “. Of the anti-Covid vaccine in the age group 12-15 years “I think all the best possible, because in fact it means further reducing the circulation of the virus. Right now we focus on immunizations in adults and on the elderly, but traditionally we gave the vaccine during deaths to children and infants to try to protect them as early as possible against terrible diseases “. “It is clear that vaccine testing on children is the last part of this step but – he explains – the fact that they are proving safe even in pediatric age groups is a very important element because it blocks the circulation of the virus”.
