How is South Africa developing its own cholera vaccine?
South Africa's Biovac has launched clinical trials for a fully manufactured oral cholera vaccine. Supported by international donors like the Gates Foundation and Wellcome Trust, the project aims to produce a vaccine entirely within the country. The trials, conducted at Wits University, are assessing the vaccine's safety and ability to trigger an immune response, with approval expected by 2028.
-
What impact could this vaccine have on cholera outbreaks in Africa?
If successful, the vaccine could significantly reduce cholera outbreaks across Africa by providing a reliable, locally produced solution. It would help contain outbreaks faster, especially in water-scarce communities, and lessen reliance on imported vaccines, which often face shortages during emergencies.
-
When might the vaccine be available to the public?
The clinical trials are currently underway, with approval anticipated around 2028. Once approved, the vaccine could be distributed to at-risk populations across Africa, improving outbreak response and prevention efforts.
-
Why is local vaccine production important for Africa?
Producing vaccines locally reduces dependency on imports, which can be unreliable during global shortages. It also allows for faster response times during outbreaks, builds regional health capacity, and supports economic development by creating local manufacturing jobs.
-
Could this development help other diseases in Africa?
Yes, establishing local vaccine manufacturing capacity can pave the way for developing vaccines for other diseases, improving overall health security and resilience across the continent.

What challenges does South Africa face in vaccine development?
Developing a new vaccine involves rigorous testing, regulatory approval, and scaling up production. Funding, infrastructure, and ensuring quality standards are also critical challenges that South Africa is working to overcome.
