According to the Daily Mail, the move would mean those travelling to the country during the February break will have to get a booster if they received their second dose any earlier than May last year.

Without a recent jab, France will effectively treat travellers as though unvaccinated and will only allow them to enter with a "compelling reason", such as on compassionate grounds.

Eurostar warned customers of the move, stating: "If you had your full vaccine course nine months ago or more AND you haven’t had a Covid-19 vaccine booster, you must follow the rules for unvaccinated passengers to enter France."

It comes amid further half-term holiday confusion, after it was announced some children could struggle to prove their Covid status in time for the break, as those seeking to provide proof of immunity from a previous infection will only be able to do so through the NHS if their infection was confirmed via an NHS PCR test, and not from a lateral flow test.

Idle Travel boss Tony Mann said agents could face a "temperamental" half-term due to different countries’ vaccination policies for children.
