SANTIAGO: The coronavirus vaccine has reached Antarctica after Chile immunized 49 people on the continent, the South American country’s air force said on Wednesday (Thursday in Manila). Chile’s immunization program has received many plaudits as authorities have managed to give five million people — almost a third of the population — at least one vaccine dose. And on Sunday, it even started immunizing members of the armed forces and scientific researchers stationed at the Presidente Eduardo Frei Montalva air base in Antarctica, with a further 53 people at the base set to receive their first dose in the coming days.
