The European Union geared up to start mass vaccinations against COVID-19 just after Christmas after the shot developed by Pfizer and its German partner BioNTech cleared regulatory hurdles on Monday.

European Union countries including Germany, France, Austria and Italy have said they 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.

Having secured a green light from the European Medicines Agency (EMA), the European Commission gave final approval on Monday evening to the EU's first COVID-19 vaccine.
