MeSH IE 11 is not supported. These findings are incredibly encouraging, considering the limitations of current tools such as seasonal malaria chemoprevention and an approved vaccine (RTS,S), which have a more complex dosing regimen and lower efficacy. When I think of the staggering number of deaths each year from malaria, mostly in children under age 5, and from RSV, which affects about 100,000 babies each year in their first 5 months of life, 10 to 15 years feels way too slow. Unlike a vaccine, which relies on your bodys ability to mount a strong immune response and takes time to develop a high level of protective antibodies, a monoclonal antibody can provide protection almost immediately after injection and can work even in people with compromised immune systems. What promise do these drugs hold? A foundation program is working to change the status quo. See theEUAfor more information.
