France Covid travel rules: Does booster dose expire after nine months?

One reader has incorrectly read that a person is no longer considered fully vaccinated nine months after getting a top-up vaccine dose. We explain the rules

Over 35 million people in France have received a Covid booster vaccine dose

Reader question: We are seeing conflicting information that booster vaccine expiry could be as little as nine months for entry to France. Is this correct?

France’s Covid travel rules state that a person who gets two doses of a two-dose vaccine approved by the European Medicines Agency (Pfizer, Moderna, AstraZeneca/Vaxzevria/Covishield) or one dose of Janssen (Johnson & Johnson) is considered fully vaccinated for up to nine months after the final dose is administered.

After that point, they will need a booster dose in order to be considered fully vaccinated.

Everyone who has had a booster dose is considered fully vaccinated, without any expiry date to this introduced, as yet, by France.

Additionally, even if you wait 10, 11, 12 or more months after your second dose to get a booster dose, once you get this you will again be considered ‘fully vaccinated’.

Take this example:

John gets a first dose of the Moderna vaccine on March 1, 2021. He gets his second dose on May 24.

John would have been considered fully vaccinated under French travel rules until February 24, 2022. For John to maintain his fully vaccinated status, and be considered fully vaccinated today, he should get a third vaccine dose, which will (under current rules) give him indefinite ‘fully vaccinated’ status.

There are other nuances to France’s definition of fully vaccinated, for example for people who were initially vaccinated with a vaccine not approved by the EMA.
