Moroccan health workers wearing protective gear collect nasal swabs and administer Covid-19 vaccines at a digitalised centre which is part of the local "smart vaccinodrome" campaign, in the Errahma district near the city of Casablanca. The digitalised centre aims to vaccinate 3,000 to 4,000 people per day and its entire vaccination programme is processed through a QR code system that allows citizens to be traced throughout the vaccination circuit.
