On what I am seeing with a pass vaccinal in the pocket
“Chers clients, Pour toute venue dans notre restaurant, vous allez devoir présenter un ‘pass vaccinal‘.” –un restaurant
“En application des mesures gouvernementales de lutte contre la propagation de la Covid-19, un passe vaccinal est exigé pour les visiteurs de 16 ans et plus. Les visiteurs de 12 à 15 ans inclus doivent présenter un passe sanitaire. Le port du masque de catégorie 1 (non fourni par le musée) est obligatoire pour tous les publics à partir de 6 ans.” —Musée d’Orsay
In order for an American to enter France today in early 2022, two vaccinations are required and possibly a booster shot if you are over 65 years old. You must test negative within a 48 hour period before boarding the airplane.
It is not clear to me if no booster would prevent entrance. When I traveled to France on February 1, 2022, I was not asked specifically whether I had a booster or not; the authorities at the various airports asked for my vaccination records and whether I had been tested for Covid before boarding the plane in Portland and before leaving the United States.



Three times at three different airports—Portland, Seattle, and Paris—I needed to show my vaccination records and my recent Covid test. Before I could go through passport control at Paris Charles de Gaulle Airport, I was separated from other passengers and sent to a red area where my recent Covid test was checked. France has designated United States and its citizens as a high risk for having Covid and red is our color. (Click on any photo to see it larger and in more detail.

Not having the booster shot while in France, if you are over 65, is a risk not worth taking.
France has instituted a passe vaccinal. It replaced the passe sanitaire.
