SAO PAULO—Brazil’s federal health regulator Anvisa on Saturday suspended the use of over 12 million doses of a COVID-19 vaccine developed by China’s Sinovac Biotech Ltd. that were produced in an unauthorized plant, it said in a statement.
Anvisa said it was alerted on Friday by Sao Paulo’s Butantan institute, a biomedical center that has partnered with Sinovac to locally fill and finish the vaccines, that 25 batches, or 12.1 million doses, sent to Brazil had been made in the plant.
