US President-elect Joe Biden received his first dose of the coronavirus vaccine on live television on December 21 as part of a growing effort to convince the American public the inoculations are safe. Biden took a dose of Pfizer vaccine at a hospital in Delaware's Newark hours after his wife, Jill Biden, did the same. Biden said, “I'm doing this to demonstrate that people should be prepared when it's available to take the vaccine. There's nothing to worry about.
