Eric Clapton announced Wednesday that he won’t perform at venues that require proof of coronavirus vaccination for people to attend, becoming one of the first major artists to rebuke a safety precaution being used for the return of live music.

The musician, a vocal critic of the British government’s response to the pandemic, responded to Prime Minister Boris Johnson’s announcement this week that vaccine passports would be required to enter nightclubs and venues. Clapton said he was “honor-bound” to push back against the public health measures.
