The Policy Advisory Panel was happy to meet physically from 2 to 5 May 2022 for its 46th session after 2 years of virtual meetings due to the pandemic of Covid-19. The panel managed to discuss all the items of the agenda in a timely manner, and then proceeded to the selection of abstracts for the 20th conference planned in 2023 in Rio de Janeiro, Brazil. A hybrid solution with possible connection through Microsoft Teams was also available so participants who could not be present could join remotely. We have good hope that this successful meeting was the first of the post-pandemic era and will be followed by many others where our members from around the world can renew contacts and work in the best possible conditions towards our common goals!
