Third dose Covid vaccine from today to the fragile, the hypotheses in the field

On the third dose of Covid vaccine to all “politics will have to be referred to what will be the scientific indications, the important thing is to be prepared when the time comes”. Thus the Undersecretary of Health Andrea Costa, guest of ‘Agorà’ on RaiTre. But what are the hypotheses in the field for the ‘booster’ dose, now administered to the immunosuppressed? Here are the words of the experts on the subject.

PREGLIASCO – “At the moment the FDA has said to vaccinate fragile people with the third dose, after which we will see in the autumn-winter, where unfortunately I believe that there will be a blow from the tail of the virus and then perhaps we will have to make a universal recall. I imagine a prospect where the anti-covid vaccine will join the anti-flu vaccine, in the same way, that of offering the annual booster especially to the people most at risk “. This was stated by virologist Fabrizio Pregliasco, Irccs Galeazzi health director of Milan, who spoke at ‘264 zoom’ on Cusano Italia TV.

“Today we are starting with the immunosuppressed, which is different from what we will do in the near future in terms of recalling the people most at risk – continued Pregliasco -. We are realizing that there is a need to do a further dose. , a three-dose schedule for immunosuppressed people and the third dose can already be done 28 days after the second because it is a confirmation and reinforcement cycle. In the short term, however – he observes – it has already been decided to give a reinforcement, perhaps a periodic booster, therefore not a third dose in the strict sense, for older people, in particular those hospitalized in the rsa, for health workers, because it has been seen that these vaccines begin to lose a little after 6 months of effectiveness in preventing infection. This does not worry us too much because for coronaviruses not even the recovered are sure to remain protected “.
