While elaborating during the 1st session of India for Vaccination e-Summit, the Episode-15 of HEAL-Thy Samvaad Dr Prof. Sanjay Rai, Professor, Dept. of Community Medicine, AIIMS, President, IPHA said that there is no need to vaccinate the people who have documented COVID-19 infection because they have developed natural immunity. Use the vaccines judiciously as they are precious. It is scientifically proven that natural immunity supports. As per Sero Surveillance, 25% population are infected, and in major metro cities like Delhi, 50% are infected including 60% of children. As per Indian data, we don’t believe that the second or the third wave of COVID strain will take place.
