Senior Specialist, Internal Medicine & Cardiology With years of experience in internal medicine and cardiology, Prof. Partha S. Karmakar brings deep clinical insight especially relevant for adult and older populations, often at higher risk from vaccine-preventable diseases. He helps shape vaccination strategies tailored to adults with comorbidities or chronic conditions — a demographic that needs special attention. By engaging with hospitals and medical institutions, he helps create collaborations and institutional support for adult immunization programmes. His advocacy for immunization in older or at-risk adults helps broaden ISAI’s reach and ensures we serve those who may benefit the most.
