The Purine and Pyrimidine Society organises a Symposium every two years. The last was held in New York, USA, in June 2015, organised by Michio Hirano. The next meeting will be held in 2017 in Gdansk, Poland, and will be organized by Tom Smolenski.

Past members of the ESSPPMM will receive information in advance of the next Symposium. Members who have paid their subscription (see Membership form) will pay a reduced registration fee for the Symposium.
