WHO Prequalifies Shanchol® Oral Cholera Vaccine, Ensuring Global Supply Continuity
Over the years, close to 40 million doses of Shanchol® have been supplied worldwide through UNICEF-led vaccination campaigns. After production was paused under its former ownership, GCBC Vaccines Pvt. Ltd. (formerly Shantha) has resumed manufacturing, with WHO conducting an on-site inspection and transferring the prequalification. Shanchol® remains the only oral cholera vaccine manufactured in India with WHO prequalification, underscoring India's critical role in ensuring continuity of global supply.

Shanchol® is a bivalent killed whole-cell oral cholera vaccine, effective against
O1 and O139. It has been a cornerstone of UNICEF-coordinated outbreak responses and preventive immunization campaigns, protecting millions of people worldwide. With WHO PQ approval, Shanchol® will continue to be supplied at scale to meet international demand and country-level immunization needs.
Shanchol® was originally developed by Shantha Biotechnics, founded in the 1990s as one of India's pioneering biotech firms. The company was acquired by Sanofi in 2009, gaining global recognition as a trusted vaccine supplier. In 2024, Shantha's facilities including Shanchol®, were acquired by GCBC Vaccines Pvt. Ltd. Today Shantha's legacy is continued, through the revival of the company and its mission to deliver high-quality, affordable vaccines that expand access to life-saving immunization worldwide.
