The European Association of Haemophilia and Allied Diseases held its 12th Congress in the Prague Congress Centre. Compared to previous years, the congress in Prague attracted a record number of participants, an increase of 25 %. In the light of snowy Prague, the Congress discussed the upcoming new treatment, i.e. genetic therapy, which could practically turn haemophiliacs into healthy people. In this respect, it was a great success for the Czech Republic that it managed to organise the congress in Prague.
