Join us to celebrate 20th anniversary of NAPRRS/NC229 Conference

NAPRRS/NC229 ICSVD was originally formed in 2003 as the International PRRS Symposium. It provides a forum for bringing together the members of swine disease community from all over the world. The 2023 meeting will be a 2-day international conference held in Chicago, USA. Tentative plans include six plenary scientific sessions starting on Friday morning (December 1), a translational workshop co-organized with the Swine Health Information Center, a special lunch session sponsored by Zoetis, a poster session and NC229 business meeting to discuss the latest research and explore collaborative relationships for new research initiatives. On Saturday evening (December 2), we will have a banquet to celebrate the 20th anniversary of NAPRRS/NC229 conference. 

The executive directorship, organizing committee, and conference staff hope that the NAPRRS/NC229 ICSVD will provide all attendees with an informative and scientifically rewarding experience.

We look forward to meeting you at Chicago!
