While thousands flock daily to health clinics and ad-hoc vaccination points across Spain, health workers also fan out across the country to take shots to some of those who are the most vulnerable to the coronavirus.

“Rain or storm, the vaccines must reach the homes,” Rodríguez said.

Spain has set the goal of vaccinating 70% of its adult population — some 33 million people — by the end of August. After being slowed by delays in shipments from drug makers, Spain has sped up its vaccination efforts and now has gotten at least one shot to almost 13 million people.

The government's priority is the elderly and most vulnerable. It has completely vaccinated 95% of people over 80.
