Probably the biggest immunization campaign against Covid-19: Dr Harsh Vardhan

"This is probably the biggest immunisation campaign against COVID anywhere in the world. India has tremendous experience in handling such issues. We have already eradicated polio and smallpox. I am very happy and satisfied today. We have been fighting against COVID-19 in PM's leadership for the last one year. This vaccine will work as a 'sanjeevani' in the fight against COVID-19, which has entered the final stage": Union Health Minister Harsh Vardhan
