The Serum Institute of India will ship the Oxford -AstraZeneca Covid-19 vaccine to Canada in less than one month, Adar Poonawalla said on Twitter on Monday. He said his company was waiting for regulatory approvals from Canada. Canada, which has recorded more than 825,000 coronavirus cases and 21,000 deaths so far, does not yet have a vaccine manufacturing facility of its own and is reliant on foreign suppliers. India boasts of several vaccine manufacturing facilities and is fast emerging as a key supplier to the world.
