A friend of mine sent me this link to an official Italian government website which mentions (Google Translate translation):

From December 15, 2021, the validity of the COVID-19 green certification for vaccination, for doses following the first or dose after recovery, passes from 12 to 9 months from the date of administration. Check when you have taken the last dose, if more than 9 months have passed, you are among those who would find themselves without COVID-19 Green Certification as a result of this variation. Book your booster dose by December 14, 2021, and you will receive the new Certification within 48 hours of administering the vaccine, which will be valid for 9 months.

Does it mean that access to Italy will be limited to those with <9 months of vaccine validity?

  • Where are you travelling from/what are the countries you will have visited in the 14 days before reaching Italy? Rules vary a lot depending on the countries involved, but in many cases, even without vaccination you can enter, you just have more requirements/restrictions. Entering with vaccination over 9 months ago would be equivalent to entering without vaccination.

    @MarkMayo What sort of clarification are you looking for? OPs original question is fairly detailed and while jcaron's questions, if answered, can provide more detail, they do not look like a blocker for the question can be put on hold. To me the OP is asking a fairly straightforward question - Does Green certificate cease to be valid if >9 months have passed from vaccination.

Update: That <9 months requirements is only relevant to accessing certain activities, such as restaurants / entertainment venues / ..

But access to Italy and trains does NOT require <9 months validity.
