Due to the global COVID-19 developments, the Dutch authorities have decided to ban all major events taking place until 1 September 2020. After lengthy and thoughtful considerations, the WC11 organization decided to postpone the 11th World Congress on Alternatives and Animal Use in the Life Science, scheduled to take place August 23-27, 2020 in the Netherlands. The new dates for the 11th congress will be August 22-26, 2021. The venue of the congress will remain the MECC Maastricht, the Netherlands.
