(Updated 5:21 p.m. EDT) -- While the global COVID-19 pandemic has shut down most cruise lines since mid-March 2020, many of the world's cruise lines have now resumed service, albeit in a limited capacity.
All these lines are operating strict new health and safety protocols that can include mandatory vaccination against COVID-19, pre-cruise or pierside PCR or antigen testing, and masking requirements onboard and ashore -- full details can be found on our continually updated health and safety feature
