SANTIAGO, Chile – A real study of millions of Chileans who had received the CoronaVac vaccine, developed by China, has found that 67% is effective against symptoms and 80% against death from COVID-19, it said on Friday. South American Ministry of Health.
Ministry adviser Rafael Araos said the study covered 10.5 million people, including 2.5 million who had received doses of the vaccine and 1.5 million who had received a single dose between the 2 of February and April 1st.
He counted the cases that began 14 days after the application of the second dose of the vaccine, which in Chile was administered 28 days after the first.
The vaccine has been widely used worldwide, though not in the United States or Europe.
Araos said he had reduced hospitalizations by 85%, intensive care visits by 89% and deaths by 80%.
It is one of the most widely published studies to date on any of the vaccines used against the new coronavirus. Most previous studies were based on clinical studies of limited groups of thousands of people who received vaccines to test for efficacy and safety before general use.
Chile has led the region with a vaccination campaign that has reached 40% of its 19 million people in general, and 27% of those who have so far received both doses. It started largely between the elderly and health workers, but has expanded to include essential workers and recently 48-year-olds.
He has contracted 60 million doses of the CoronaVac vaccine produced by Sinovac for three years, and has also been using vaccines produced by Pfizer. About 90% of the vaccines used so far in Chile have been CoronaVac.
Authorities reported Thursday that Chile had seen a sharp reduction in the hospitalization of people aged 70 and over, which was credited to the vaccination campaign among the elderly. But it has also seen a “sustained increase” in hospitalizations of people aged 59 and under.
The country has reported 1.1 million infections confirmed by the new virus and nearly 25,000 dead.
