“Just completed the Oxford Covid-19 vaccine trial,” the 72-year-old “Cats” composer captioned a photo of himself receiving the vaccine on Thursday. “I’ll do anything to get theatres large and small open again and actors and musicians back to work.”

Webber announced he would be participating in the vaccine trial, which is being developed by the University of Oxford and pharmaceutical company AstraZeneca, on Wednesday.

Fans immediately praised Webber for volunteering. “Much respect to you, sir,” one Instagram user commented. Another added, “that’s very brave, thank you Andrew.”

The coronavirus pandemic halted all Broadway shows in March and the shutdown has been extended until January 2021. West End shows in London have also been shuttered amid the pandemic.
