On Tuesday, President Biden is scheduled to visit the vaccination site at Virginia Theological Seminary in Alexandria, Virginia.
Biden plans to tell Americans that "this is the time to go", Psaki said. That puts the president well on track to meet his new goal of 200 million shots administered by his 100th day in office on April 30.
Psaki's comments come one day after she refused to answer whether Biden would continue peddling false claims about Georgia's voting law, including that "the law would end voting at five o'clock when working people are just getting off", a claim which the Washington Post's fact-checkers gave four Pinnochios - a rating reserved for the most misleading, incorrect statements - because that part of the law gives counties the option to extend voting hours.
Several states have already opened up eligibility to residents 16 and up or announced plans to do so by May 1. They have also argued that other states, including Biden's native DE, have more restrictive voting regimes.
The president had announced just last week that 90% of adults would be eligible for one of three approved vaccines by April 19, in addition to having a vaccination site within 5 miles of their home.
But eligibility isn't the same as actually being vaccinated.
After that, Biden will deliver remarks on the state of vaccinations in the State Dining Room of the White House, where he will announce the new goal and celebrate the 150 million vaccinations. That means Americans no longer need to check with state and local websites to see whether they qualify, she said.
About 32% of Americans have received at least one vaccine dose and almost 19% are fully vaccinated.
The White House said Monday that almost 1 in 3 Americans and over 40 per cent of adults have received at least one shot, and almost 1 in 4 adults is fully vaccinated.
Pfizer and BioNTech's two-dose vaccine series are authorized for people aged 16 and up, while Moderna and Johnson & Johnson's vaccines are only authorized for adults 18 and above.
