Authorities in Curacao on Saturday boarded a ship that arrived under quarantine to start vaccinating people to prevent a measles outbreak. Health officials said only those who already have been vaccinated or have previously had measles will be free to leave the 440-foot (134-meter) ship Freewinds, which belongs to the Church of Scientology. Authorities worry people aboard the ship might have been exposed after a female crew member was diagnosed with measles after coming back from Europe. Curacao health officials then alerted authorities in St. Lucia. Gerstenbluth said it would be easy to spread the disease given that it's a small ship.
