The Ministry of Home Affairs (MHA) on Wednesday ordered Y-category security for Serum Institute of India (SII) chief executive Adar Poonawalla, ANI reported. The Central Reserve Police Force (CRPF) will provide pan-India security to the 40-year-old.

Earlier today, Poonawalla said that as a "philantrophic gesture", the Pune-based firm will cut the price of its Covishield vaccine for states from Rs 400 to Rs 300 per dose.

SII had earlier announced it will sell its stock to states for Rs 400 per dose and to private hospitals at Rs 600 per dose. Poonawalla justified those prices by saying that they were based on advanced funding, and that the firm needs to invest in scaling up its capacity to produce more doses.
