Chile declared on Aug. 5 that it will administer booster vaccines to citizens who have received China’s Sinovac in order to raise immunity. The move comes after finding the initial doses lose some effectiveness after several months’ time.
Chile is one of the Latin American countries that has done most of its vaccinations with China-made COVID-19 vaccines—including Sinovac’s CoronaVac. The country launched a mass vaccination campaign in February and has now fully vaccinated more than 60 percent of its population.
