This island could be the first fully vaccinated territory in the world By James Frater, CNN enablePagination: false endIndex: (CNN) - The tiny remote Ascension Island in the South Atlantic Ocean could “become the first island to be fully vaccinated against COVID-19,” the British Military said Friday. The island – a UK overseas territory – has a population of just over 800 inhabitants. At least 1,950 doses of the AstraZeneca COVID-19 vaccine arrived at Ascension earlier this week on a special support flight by the Royal Air Force. Staff at the island’s Georgetown Hospital have begun administering the vaccine and the first people to vaccinated were hospital employee Sylvia Isaac and her husband Mervyn.
