Chile starts fourth vaccine dose as coronavirus cases rise

SANTIAGO, Chile (AP) — Chile is implementing a fourth vaccination dose for some citizens as the number of daily coronavirus infections rises. President Sebastián Piñera was present on Monday when two adults with immunosuppression problems received a fourth vaccination for COVID-19 at a Santiago hospital. Piñera says Chile is applying a fourth dose early because the current daily infection rate of 4,000 coronavirus cases could rise to 10,000 or more.  Vaccination with a fourth dose for the immunosuppressed will end on Feb. 7. Then the program will turn to people over 55 years old who had a third dose at least six months ago.
