Doctor SP Byotra, Chairman Department of Medicine, Sir Ganga Ram Hospital said,

There is a notion in the public that once a person gets vaccinated he becomes immune to any infection but this is an antigen that will produce antibodies in a person within a stipulated time. If a person gets the infection even after getting the vaccine then it should not be considered as a failure of the vaccine.

Several vaccines required to be given in two doses. First is a half dose which starts stimulating the production of antibodies followed by the second which maintains a high level of antibodies in the body.

Dr Prasun Chatterjee, Associate Professor, Department of Geriatric Medicine, All India Institute of Medical Sciences said,

Covaxin is a killed virus which once infused in a human body some of the property like surface glycoprotein stimulates antibodies. What is dangerous for Covid is the glycoprotein. One-shot gives partial protection but booster is better. It stimulates the immune system twice.

It aims to spread awareness about critical health issues facing the country. In wake of the current COVID-19 pandemic, the need for WASH (WaterSanitation and Hygiene) is reaffirmed as handwashing is one of the ways to prevent Coronavirus infection and other diseases. The campaign highlights the importance of nutrition and healthcare for women and children to prevent maternal and child mortality, fight malnutrition, stunting, wasting, anaemia and disease prevention through vaccines. Importance of programmes like Public Distribution System (PDS), Mid-day Meal Scheme, POSHAN Abhiyan and the role of Aganwadis and ASHA workers are also covered.
