Mandatory green pass and difficulty in downloading it, even the paper certificate of vaccination can work as a green certificate. To clarify this is the Undersecretary of Health, Andrea Costa, guest of the program ‘Let’s see it clear’ on Tv2000. “Regarding the difficulties in downloading the Green pass, there are some critical issues that we are solving but at the same time the paper certificate of vaccination that acts as a Green pass is also valid”, explained Costa. The undersecretary then reiterated that “it is reasonable to think that already by the end of the year there could be an extension of the audience of those who have to receive the third dose of the vaccine. The data tell us that protection falls after a certain period of time. It falls more rapidly. in the elderly and more slowly in the young. It is clear that we must prepare ourselves for a third dose which is likely to be extended to the entire vaccine audience “.
