France will impose new rules on over-65s next month that mean they can only travel or visit restaurants or attractions if they have had a booster jab.
President Emmanuel Macron told over-65s in a TV address: “From 15 December, you will need to provide proof of a booster jab to extend the validity of your health pass.”
He added: “We have not finished with the pandemic.”
He said infection rates had increased 40% over the last week.
The health pass was introduced in France in late July.
People need to show proof of vaccination, a negative test or recent recovery from COVID to enter most museums and cinemas, or travel by train and aircraft.
