President Joe Biden and first lady Jill Biden shared well-wishes with Americans celebrating Easter on Sunday and encouraged them to get Covid-19 vaccinations as a moral obligation.

"We share the sentiments of Pope Francis who said that getting vaccinated is a moral obligation, one that can save your life and the lives of others," the President said in a video posted on his Twitter account.

"By getting vaccinated and encouraging your congregations and your communities to get vaccinated, we not only can beat this virus, we can also haste the day when we can celebrate the holidays together."

The first lady said there is "hope all around us" and mentioned families receiving financial help, businesses recovering and an increase in Americans receiving vaccinations against the virus.

The message from the Bidens comes as health officials race to vaccinate as many Americans as possible amid concern over a potential fourth wave of coronavirus infections. The US Centers for Disease Control and Prevention reported Saturday that more than 4 million doses of the coronavirus vaccine had been reported administered in 24 hours, setting a new record and bringing the seven-day average to more than 3 million a day. Across the country, more than 161 million doses have been administered, according to agency data.
