Serum Institute of India halts vaccine production over millions of unused doses
Serum Institute of India, a key supplier of Covid-19 inoculations to developing countries, has stopped making fresh batches of shots after its stockpile grew to 200 million doses amid a global supply glut. Serum’s chief executive officer Adar Poonawalla said on Friday that the company had more than 200 million doses of inventory, so had to shut down production in December.
