The green pass from 15 October is mandatory to access work, public or private. “To those who from 15 October will have to spend a lot of money on annoying tampons to get the Green pass, I remember that there is a free alternative: get vaccinated and enjoy the money saved with greater peace of mind”, writes Roberto Burioni, virologist of the Vita-Salute San University Raffaele in Milan, on Twitter. The green pass, for those who do not vaccinate against the coronavirus, is issued in case of negativity to a swab performed 48 hours before.
