Programme - day 2
The programme for the second day of the HTHP Symposium 2024 gives you individual tracks to choose from and the option to go on interesting site visits.
On the second day of the HTHP Symposium, the programme is divided into two time slots which consist of different sessions to choose from. The final session of the HTHP Sympoisum is a closing session which sums up the main points delivered during the two days and looks forward to what is coming.
Following the HTHP Symposium, participants have the opportunity to go on a site visit to various destinations. You can read more about the different site visits here.
