PARIS — French teenagers aged 12-18 will be eligible for COVID-19 vaccination from June 15, President Emmanuel Macron said on Wednesday.

The announcement comes as France hit a vaccination milestone on Wednesday, with 50 percent of the adult population inoculated with a first dose.

"Today we will pass the symbolic mark of 50 percent of adults having received the first injection," government spokesman Gabriel Attal told reporters earlier on Monday at a regular press briefing.

But Macron also warned that the French should remain "extremely cautious" as coronavirus indicators deteriorated in southwestern regions.

The deterioration was "particularly marked in the Pyrénées-Atlantiques" and "to a lesser extent in Charente-Maritime, Lot-et-Garonne, Charente, Landes and Gironde" areas, Attal said.

He warned against relaxing measures too early.

Teens vaccinations elsewhere in Europe

The EU regulator authorized Pfizer-BioNTech’s COVID-19 vaccine for use in children as young as 12 last week.

Other EU countries have already extended their vaccination campaign to teens.

Romania on Wednesday started administering COVID-19 vaccines to teenagers aged 12 to 15

Italy on Monday approved the use of the Pfizer-BioNTech shot to 12-15-year-olds.

Germany plans to offer the first jab to children aged 12-16 from June 7, while Poland would start inoculating those aged 12-15 the same day.

But the vaccination of children in rich countries while many parts of the still struggle to innoculate older and more vulnerable people has sparked controversy.
