Biden's goal equates to delivering at least the first shot to 181 million adults and fully vaccinating 160 million.

Biden has regularly implored Americans to get a vaccine, avoid large crowds and continue Covid-19 mitigation efforts a bit longer to drive the caseload down in time for July 4 celebrations. Biden urged states to administer at least one dose to adolescents by July Fourth and work to deliver doses to pediatricians' offices and other trusted locations, with the aim of getting many of them fully vaccinated by the start of the next school year.

The administration realizes that the people who are most enthusiastic about being vaccinated already have been, per NPR.

Currently, only the Pfizer vaccine is approved in the US for people as young as 16. Those states would have the shots available whenever demand for vaccines in their states increases - a key priority of the Biden administration.

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.

Administration officials who asked not to be identified said Biden would announce the ambitious goal in a speech later Tuesday.

The White House is also launching a comprehensive plan to inoculate adolescents once the Food and Drug Administration authorizes the Pfizer vaccine for younger people, as expected within weeks. Though White House officials privately acknowledge the steep challenge, Biden sounded an optimistic note.

"If we make progress towards this goal, more and more Americans will gain protection from COVID-19. and America will have taken a serious step toward a return to normal", one official told reporters on a conference call.

This week, Iowa turned down almost three-quarters of the vaccine doses available to the state for next week from the federal government because demand for the shots remains weak.

As part of the push to get more shots in arms, the White House told governors on Tuesday it will be tweaking the allocation system for vaccines.

The White House previously resisted efforts to shift vaccine by metrics other than population, with Biden rebuffing Michigan Gov. Gretchen Whitmer last month when she requested more doses as her state was experiencing a surge in virus cases. Louisiana, meanwhile, hasn't drawn down its full vaccine allocation from the federal government for the last few weeks.

President Biden predicted Monday that the United States would be in a "very different position" by the end of the summer when it comes to the number of Americans vaccinated against the novel coronavirus.

The New York Times reported Monday that most scientists and public health experts believe that the US will not reach herd immunity, at least not in the near future.

The weekly allocations will still be determined by adult population, however states had been allowed to carryover unordered doses week-to-week in case they needed them in the coming weeks. Previously the state doled out supplies to counties proportionate to their populations.
