A hivatalos francia oldalon ezt írják:
The vaccination schedule is considered complete 28 days after receiving one dose of Janssen vaccine, seven days after a second dose of other vaccines approved by the European Medicines Agency (namely Pfizer/Comirnaty, Moderna, AstraZeneca/Vaxzevria/Covishield) and, for persons who have received all the required doses of a WHO-licensed vaccine not approved by the European Medicines Agency, seven days after receiving an additional dose of a duly approved mRNA vaccine.

Ezek szerint - legalábbis ma még - belépni az országba tényleg lehet egy Janssen-nel, a 2 hónapos időkorlát nélkül.
