Fifty-five fully vaccinated passengers on a Royal Caribbean cruise ship have reportedly tested positive for COVID-19, causing the ship to be denied access at two island ports.

The cruise line said 95% of people on board the Odyssey of the Seas ship were fully vaccinated. The vessel set sail on Saturday from Fort Lauderdale, Florida, and was later denied entry into Curacao and Aruba due to the surging cases on board, CNN reports.

The ship will idle until it is scheduled to return to Fort Lauderdale on Sunday, Local 121 reports.

"The day before yesterday, 18 crew members were positive, yesterday 36, and this morning there were 51. In addition, several crew members have not been quarantined, so there is a good chance that passengers have also been infected," said Dr. Izzy Gerstenbluth, Curacao's national epidemiologist. "With these numbers of infections, that percentage has been exceeded, and we are therefore not eager to receive these people on the island, especially not with the current figures on the island."

The ship can hold up to 5,500 guests and 1600 crew members, according to the cruise line. It is unclear if full capacity was reached at the time of the outbreak.
