CERVAVAC, India’s first homegrown cervical cancer vaccine, is priced at just $2.50 to $5.00 per dose — a fraction of what HPV vaccines have cost in wealthy countries for nearly two decades. Developed by the Serum Institute of India, it protects against the HPV strains responsible for the majority of cervical cancers worldwide, and the company aims to produce around 200 million doses in its first two years. Cervical cancer is almost entirely preventable, yet it still kills hundreds of thousands of women each year, mostly in lower-income countries where vaccines have been priced out of reach. An affordable, locally made option doesn’t just change the math for India — it points toward a future where health tools belong to the people who need them most.
