Carnival cited the order in announcing the updated vaccination rules, saying it was adapting to “evolving requirements of some of its destinations.”
The mandate applies to departures from all Atlantic and Gulf homeports, the company said. Previously, Carnival followed U.S. Centers for Disease Control guidelines requiring at least 95 percent of all guests and crew be fully vaccinated; the cruise line said all of its crew members have gotten the shots. The new rule is effective Aug. 28 through October.
“The requirements for cruise ships to enter ports outside the U.S. continue to evolve, and Carnival Cruise Line must operate in full compliance with these regulations,” Carnival brand ambassador John Heald wrote on Facebook. He added, “We believe these will be will temporary measures and apologise for any disruption caused to our guests.”
Other major cruise lines had already imposed strict inoculation requirements, despite a Florida law that bans companies from demanding proof of vaccination against the coronavirus.
Royal Caribbean also updated its vaccination policy to comply with the Bahamas order. For cruises departing from any U.S. port, the shots are required for all guests over 12.
