Chile has endured a sharp uptick in Covid infections in recent weeks, even with its world-renowned vaccine rollout and strict lockdowns in place.
A study published by the University of Chile earlier this month reported that CoronaVac was 56.5% effective two weeks after the second doses were administered in the country. Crucially, however, they also reported that one dose was only 3% effective.
"I cannot stress this enough — for most countries, vaccines are not going to stop this wave of the pandemic," Carissa Etienne, director of PAHO, said during a weekly press briefing on Wednesday.
