Maharaj Kishan Bhan

Dr. Maharaj Kishan Bhan was an Indian paediatrician (children’s doctor) and scientist who helped make important vaccines and healthcare innovations reach people in an affordable way.

• What he is known for: He played a major role in developing the Rotavirus vaccine, which helps protect young children from severe diarrhoea.
• Why this matters for health: Rotavirus infection can cause dangerous dehydration in babies and small children. Preventing it through vaccination can save lives, especially where quick medical care may not be easy to access.
• His leadership role: As Secretary of India’s Department of Biotechnology, he supported research and encouraged new scientific ideas that could improve public health.
• A key idea he stood for: Science should not stay only in laboratories—its benefits should reach ordinary people as safe, effective, and affordable healthcare.
• How this connects to immunity: Work like his strengthens acquired immunity in communities by helping more children get vaccinated before they face the real infection.

He is remembered as a scientist who combined medical knowledge with public service to make disease prevention more accessible for children.
