President Joe Biden has said he is hopeful that America can “mark independence” from Covid-19 on 4 July if people get vaccinated.

In his first primetime address as president, Mr Biden said he would order states to make all adults eligible for vaccinations by 1 May. Current measures prioritise people by age or health condition.

Mr Biden was speaking exactly a year to the day after the outbreak was classified a global pandemic. Half a million Americans have now died – more than the death toll from World War One, World War Two, and the Vietnam War combined.

This time last March, all US major sports were cancelled and then-President Donald Trump suspended travel from Europe. He also said he hoped the US would be open again for Easter.

In his speech, President Biden eyed another important date in the calendar for when small groups could meet again.

“If we do this together, by 4 July, there is a good chance you, your family and friends can get together in your backyard or in your neighbourhood and have a cookout or a barbecue and celebrate Independence Day,” Mr Biden said. He added that the country would be able to not only celebrate Independence Day but also “independence from this virus”.

As part of the plans to expand vaccinations, the number of places where people can be immunised will be increased, with veterinarians and dentists among those also allowed to vaccinate people.

Mobile units will travel into local communities to provide vaccinations in underserved communities, the president said.

Mr Biden set a target of 100 million vaccinations by his 100th day in office but in his address, he said this target would be reached on day 60. Despite the good news, he warned that the “fight is far from over”. “This is not the time to let up,” he added.

He called on people to maintain social distancing measures, hand washing and wear a mask. “Beating the virus and getting back to normal relies on national unity,” he said.

The president said last month he hoped that life would return to “normal” by Christmas 2021. Dr Anthony Fauci, the top US infectious diseases expert, described this prediction as “reasonable”.

One year ago, the United States joined the world in facing a brutal truth. The coronavirus pandemic was going to fundamentally alter everyday life. Businesses shuttered. Citizens sheltered in their home. Life ground to a halt.

On Thursday night, in his first prime-time televised address to the nation, President Joe Biden said there was light at the end of the tunnel.

The big news from his speech was that all adult Americans would be eligible for a vaccine by the beginning of May – a pace, he boasted, that was the best in the world.

His most important message, however, may have been his urging that all Americans should get the jab when it’s their turn. “I know they’re safe,” he said.

A recent opinion poll showed that nearly half of Republicans are sceptical of the vaccine. If their doubt becomes inaction, Biden’s promises – widespread school openings, an ability to travel and Independence Day celebrations – will go unrealised.

His speech was part promise, part warning. Get vaccinated, continue social distancing, wear masks – or else.

“America is coming back,” he said. But, he added, Americans needed to do their part.
