The vaccines accepted are those recognized by the European authorities, which is the case for all vaccines administered in the United States: Pfizer, Moderna, and Johnson & Johnson. In order to be considered as vaccinated, a delay is required:-either 2 weeks after the 2nd injection for double injection vaccines (Pfizer, Moderna)-4 weeks after the injection for vaccines with a single injection (Johnson & Johnson)-or 2 weeks after the injection for vaccines for people with a history of Covid-19 (only one injection is required for any vaccine).
