In a groudbreaking announcment made last week, the World Health Organization ruled that the MenAfriVac vaccine, which is already having a big impact in the "Meningitis Belt" of Africa, can be safely used even after four days without refrigeration.

This annoucment paves the way for other vaccines to be approved for use after heat exposure and is an important step towards increasing equitable access to vaccines.
