The experts agree that the data contained in slides gives a good reason for us to return masks in some high-risk environments.

"We did a great job to tell the public these are miracle vaccines," said Seeger. "We have probably fell a bit in the trap to reassure too much, which is one of the challenges of any circumstance of crisis communication. »
