A single dose of yellow fever vaccine does not offer lasting protection to all children
Yellow fever is a viral infection spread by various species of mosquito and is rife in 34 countries in Africa and 13 in Latin America. Infection may be asymptomatic and go unnoticed or, on the contrary, it may progress rapidly…
Towards better hand hygiene for flu prevention
Washington, DC – September 18, 2019 – Rubbing hands with ethanol-based sanitizers should provide a formidable defense against infection from flu viruses, which can thrive and spread in saliva and mucus. But findings published this week in mSphere challenge that…
