Congress interim president Sonia Gandhi has written a letter to Prime Minister Narendra Modi over the new vaccine policy. She has described the government's new policy for vaccination as arbitrary and discriminatory. Yesterday Rahul Gandhi also came up with his questions on the new vaccine policy. Sonia Gandhi urged PM Modi to allow the emergency use of those Covid-19 vaccine candidates, which have the required clearance. She also underscored the need for a vaccine prioritisation strategy for effective results in the fight against the virus. Congress leaders are consistently raising the questions, that who will bear the prices of vaccines decided by the Serum Institute of India for the state governments and private hospitals.
