On Wednesday, Germany’s health minister expressed concern that it had not been properly tested.
”It can be dangerous to start vaccinating millions… of people too early because it could pretty much kill the acceptance of vaccination if it goes wrong,” Jens Spahn told local media.
”Based on everything we know… this has not been sufficiently tested,” he added. “It’s not about being first somehow—it’s about having a safe vaccine.”
