The administration's new plan will also focus heavily on working with states and national pharmacy chains to encourage walk-in appointments for COVID-19 vaccines to make it easier for those who want to get vaccinated.
As of Tuesday, the CDC reports that 56% of the adult population has one shot of the vaccine, and about 105 million adults are fully vaccinated.
The president's chief medical adviser, Dr Anthony Fauci, has said children will probably need to be vaccinated in order for life to return to normal.
But, at the same time, he acknowledged how hard it will be to convince millions of vaccine skeptics to take the shot.
Senior administration officials previewed the announcement Tuesday before Biden's planned speech from the White House.
However, vaccination rates have been trending downward and polls show that a considerable slice of USA adults do not plan to get a vaccine. It will also offer roughly $630 million in additional funding for local governments to step up outreach campaigns and hire community workers tasked with identifying and contacting people who haven't yet been vaccinated, with a particular emphasis on people of color, people with disabilities, and those in rural areas.
As part of the new phase, the Biden administration will also tell states they will begin changing how COVID-19 vaccine shots are allocated, in response to some states showing a lower demand.
Ahead of the Food and Drug Administration's expected authorisation of the Pfizer vaccine for adolescents aged 12-15 by early next week, the White House is also developing plans to speed vaccinations to that age group.
Biden touted creative efforts to make it "easier and more fun" to get vaccinated, such as grocery stores offering discounts to shoppers who come to get shots and sports leagues that hold promotions to gets shots for their fans.
The new goal comes as demand for vaccines has dropped off markedly nationwide, with some states leaving more than half their vaccine doses unordered. Officials hope that extending vaccinations to teens - who would be eligible to get the first dose in one location and the second elsewhere - will further accelerate the nation's reduced virus caseload and allow schools to reopen with minimal disruptions this fall. The administration says that when states decline to take all the vaccine they have been allocated, that surplus will shift to states still awaiting doses to meet demand.
Vaccines have been allocated state by state based on population - a formula the Biden administration held to even as some states such as MI saw increases in coronavirus infections.
Biden will announce that the administration is making almost $1.5 billion in funds from the coronavirus rescue package available for community organizations, rural health clinics, and state and local governments as part of the push to increase vaccination and testing rates in underserved areas. Louisiana, meanwhile, hasn't drawn down its full vaccine allocation from the federal government for the last few weeks.
Individual states have made similar shifts internally to account for changing demand.
The Democrats told reporters that they were hopeful that Tai, a former House Democratic staffer, would announce new action on the waiver at WTO sessions this week. Previously the state doled out supplies to counties proportionate to their populations. But Gov. Jay Inslee said Thursday that the amounts now will be based on requests from health care providers.
