Currently all the opera houses are closed for the rest of the season and the government hasn't given any dates of a possible re-opening.

But, again, no dates or plan on WHEN this will be in place.
11.9% of the population is vaccinated with 1 dose and 5% with 2 doses. A vaccine pass is being discussed but more relevant to travel within the EU, rather than to be used for cultural events.
