Do you want to know what happens on a malaria challenge day? Or how much force is required to take a bone marrow sample? Or maybe you wonder what we can learn about children in Africa by studying adults in the UK? Last night we ran a live event where we talked about the science behind the BIO-004 clinical trial and then opened the floor for any questions from our audience. They really put us on the spot! And you can watch the whole thing right here. Find out why we need to change the way we protect children against malaria and how we keep our volunteers safe when they take part in a malaria challenge study.
