Sounds like it potentially will get interesting on the French Side in August...and how does a visitor get a "Health Pass"?

Quote
As of August, the health pass is required to be shown for commercial centres, bars and restaurants, trains and planes as well as in hospitals and retirement homes. Restaurants that fail to check health passes face stiff fines. Vaccinations are now mandatory for nurses, health workers and retirement home employees.

It was understood from the Préfecture that all the measures will apply in St. Martin, however, confirmation of this is awaited when the decree is signed by the préfet.
