We want to see increased interest and investment into the research and development of vaccines for neglected diseases, including Lassa fever. Neglected diseases are mainly prevalent among impoverished communities in tropical areas, are estimated to affect more than 1 billion people, and frequently cause significant public health issues. However, with neglected diseases rarely or never affecting people living in wealthier countries, there is limited attention and funding into vaccine research and development for these diseases. Safe and effective vaccines, including against Lassa fever, would be an impactful contribution to reducing the burden of neglected diseases in affected areas.
