Open Philanthropy recommended a grant of $4,000,000 to the International Vaccine Institute (IVI) to support their work on a clinical trial of hecolin, a vaccine against Hepatitis E, in pregnant women. Hecolin is currently approved for use in some countries, but the World Health Organization has not yet recommended it for routine use in general populations because its safety in pregnant women has not been proven.
This falls within Open Philanthropy’s focus area of scientific research, specifically within its interest in advancing human health and wellbeing.
