(Reuters) -Germany's BioNTech said it was preparing to send 12.5 million doses of the COVID-19 vaccine it has developed with U.S. drugs giant Pfizer to European Union countries by the end of the year.

EU member countries including Germany, France, Austria and Italy plan to start vaccinations from Dec. 27 as Europe tries to catch up with the United States and Britain, where inoculations began earlier this month.

The vaccine won regulatory clearance for use on people over 16 years old from the European Medicines Agency (EMA) on Monday.

The government aims to provide a free inoculation to everyone who wants one by mid-2021.
