Europe's drug regulator is ramping up COVID-19 inoculations.
The European Medicines Agency says it's currently reviewing use of Pfizer's vaccine for children as young as five.
Last week Pfizer and its German partner BioNtech submitted results from a clinical trial on more than 22-hundred participants.
It showed the vaccine induced a strong immune response in children five to eleven.
The EMA has also given approval to vaccine manufacturing sites for Pfizer in two Italian cities to produce up to 85 million additional doses for the EU.
