AS of now, no vaccination or recovery certificates or test results (neither PCR nor antigen test) are required for entry into Switzerland. Also, an entry form no longer needs to be presented.
This applies at EuroAirport for all passengers with Swiss citizenship or a residence permit for Switzerland, for all others the French rules apply.
Entry into Switzerland is unrestricted for Swiss nationals, persons holding a residence permit, and authorised cross-border commuters. For nationals of all Schengen states, normal entry requirements apply.
Switzerland has eased the entry restrictions for persons arriving from non-Schengen countries and third countries who can prove they have been vaccinated.
The interactive travel check tool shows you what measures apply to you.

A good tip: Contact the authorities ahead of your trip to check the applicable entry requirements.
