Covid-19, after the mask and distancing vaccine

SALVATORE, just turned 80, comes out satisfied from the Mostra d’Oltremare in Naples where he has just been vaccinated with the second dose of the Pfizer / BioNTech vaccine, but he covers himself with two masks and when he returns home he sanitizes his hands to protect his wife Giuseppina, 82, with atrial fibrillation and various other comorbidities, still waiting to be vaccinated at home.
