Serum Institute of India has taken a lot of heat after pricing the COVISHIELD vaccine at ₹150 per dose for the Government to sell abroad, but ₹400 and ₹600 per dose for state governments and private hospitals respectively. CEO Adar Poonawalla has said on Saturday that it is inaccurate to compare global pricing with Indian pricing since it is based on order volume, and that “COVISHIELD is the most affordable COVID-19 vaccines available in the market today”.
