Butantan biomedical institute in Brazil's Sao Paulo state is in talks to sell a locally manufactured COVID-19 vaccine developed by Chinese biopharmaceutical company Sinovac Biotech (Nasdaq:SVA) to other countries in South America and Africa, Reuters news agency reported on Thursday.

The Brazilian federal government has not ordered more of Sinovac's COVID-19 vaccine doses, but Butantan has contracts to supply the vaccine directly to Brazilian states.

Currently, Butantan is producing Sinovac's CoronaVac shot using inputs imported from China. It aims to complete a factory for 100% local production by early next year.

Earlier this month, Butantan completed its contract to deliver 100 million doses of CoronaVac to Brazil's Health Ministry, without another deal in place.
