For those persons who have received their Covid-19 vaccinations in the USA, or many other foreign countries, it is advisable, and in some cases mandatory, for entry into certain venues and facilities in Switzerland that one has a Swiss Covid Certificate.
The CDC vaccination certificate from the USA, as well as the official government vaccination certificate from many other countries, can be used to secure the Swiss Covid Certificate, which is recognized equally within all the Schengen and EU countries.
Below is a link to the Swiss website where one can apply for the Swiss Covid certificate in English. There is no charge for residents and Swiss citizens.
