On Monday Adar Poonawalla, the chief executive of Serum Institute of India (SII) – the world’s largest vaccine maker – reaffirmed that commitment.

“As we await regulatory approvals from Canada, I assure you, @SerumInstIndia will fly out #COVISHIELD to Canada in less than a month; I’m on it!” Poonawalla said in a Tweet, using the brand name under which Serum produces the shot developed by Oxford University and AstraZeneca Plc.

India’s SII has emerged as a key vaccine supplier amid the pandemic. Canada, like many other countries, is relying on foreign supplies because it is unable to produce the vaccine locally.
