Brazil to buy single-shot Chinese COVID-19 vaccine

Brazil plans to buy 60 million doses of the single-shot COVID-19 vaccine developed by China's CanSino Biologics for delivery in the third and fourth quarters of this year, according to a negotiation document reviewed by Reuters. A ministry official signed a letter of intent on June 4 to purchase the doses with a Brazilian pharmaceutical company that represents CanSino in Brazil, Belcher Farmaceutica do Brasil, the document said. The vaccine, trade-named Convidecia and developed by CanSino together with a research institute linked to the Chinese military, will cost $17 per dose, it said.
