My understanding is that from April, they won't be doing these. They've also reduced the number of vaccs to 2 - when I booked in October for a July cruise, the requirement was 3. I'd not had any & had to decide what to do so went ahead & had 2 with the 3rd due in April. However, in Feb, govt guidelines changed & they stopped offering 3rd jabs. Ambassador then sent an e-mail a couple of weeks ago saying that they now only required 2. & I think said they would no longer be testing prior to sailing.
