India’s biggest vaccine maker, the Serum Institute of India, which produces Covishield, complained of shortages of specialised materials from the US, and its chief executive, Adar Poonawalla, appealed to President Joe Biden to end the restrictions and the firm had said that it faced difficulties importing cell culture media, single-use tubing and specialised chemicals. The Indian authorities also halted large exports of Covishield in March, although some smaller donations to other countries were allowed to go ahead. Does india need US help to produce more help ?
