Reading one of the recent post, it states:

Those guests considered unvaccinated should show a negative result for a PCR or antigen test taken no more than one day before boarding day.

Passengers who are unvaccinated by the European Medicines Agency (EMA) or who are not up-to-date with their vaccines will require additional testing during sailings from Italy. This onboard testing will be at the guest’s expense at $55 per test.

This confuses me as to if a vaccine is required or not.  Would appreciate input.
