News that worries Italy and the whole world: positive for coronavirus less than a week after receiving a dose of Pfizer vaccine. To be positive is Antonella Franco, director of the infectious diseases department of the Umberto I hospital in Syracuse, who underwent a smear after receiving the serum and was infected. And not only: She is currently interned in the department she directs.. It should be noted, however, that positivity after administration of the first dose of vaccine can happen. In fact, full immunization occurs only a few weeks after receiving the drug, so the doctor may have contracted Covid immediately before or after the vaccination. However, the doubts raised by this story remain. But not only that: the structure had organized a bus for the trip to Palermo, where the vaccine was administered, and now it is feared that the other people on board, now, may be infected. Pfizer, however, knows that the vaccine offers protection ten days after the first dose and the protection is reinforced after the second injection.
