Lee attended the European B Cell Network 2nd B Cell Summer School in Lohr am Main, Germany from 7-10 July. It was a fantastic programme in a relaxed setting, with faculty talks highlighting current B cell knowledge and invited keynotes working on cutting-edge B cell research. Lee gave a 15 minute talk on his DPhil project evaluating the influence of vaccination route and delivery kinetics on the B cell response, which generated lots of interest and excitement. Lee came away from the Summer School with new connections and even more ideas on where to take his project!
