President-elect Joe Biden said Thursday he does not believe the coronavirus vaccine should be mandatory but added that he will strongly encourage Americans “to do the right thing.”

“I don’t think it should be mandatory. I wouldn’t demand it to be mandatory,” Biden said at a news conference in Wilmington, Del. “Just like I don’t think masks have to be made mandatory nationwide.”

“I’ll do everything in my power as president of the United States to encourage people to do the right thing and when they do it, demonstrate that it matters,” he said.
