As European and Belgian guidelines are likely to change in the following weeks/months, we will wait before detailing the rules that will have to be followed at the time of the Colloquium. However, important information on current COVID safety rules and travel regulations is already available on the following sites:

• European Commission's overview of travel regulations
• Belgian travel regulations 
• Belgian Covid safety rules

Please pay a special attention to the quarantine rules depending not only on your vaccinal status but also on the vaccine you got.
