IPOPI is glad to announce that next IPIC will be held in Berlin, Germany, on 3-5 November 2021. We have chosen a great centrally located venue (Hotel Berlin Central District) near the Tiergarten and hope to meet up with many researchers and physicians with an interest in human inborn errors of immunity.IPIC2021 will build on our previous events and promises to deliver a diverse and stimulating scientific programme focusing on the state of the art in primary immunodeficiencies (PID) diagnosis and clinical care.
