The RTS,S clinical trial, which ran from 2009 to 2014, tested the vaccine in 6 to 12 month-old infants and in older children, 5 to 17 months of age. Experimenters took multiple blood samples from the children over a 32-month period, including before and after they received their shots. The infants received almost no protection from malaria, while for the older children, the vaccine was more than 30% effective.
