The Biden administration won't hit its goal of getting 70% of adult Americans at least partially vaccinated for COVID-19 by July 4.

The Biden administration won't reach its "aspirational" goal of getting 70% of adult Americans at least partially vaccinated for COVID-19 by the Fourth of July, White House Coronavirus Response CoordinatorJeff Zients said Tuesday.

Sixteen states and the District of Columbia have reached the goal already – but some states are at less than 50% of all adults, Zients said at a White House briefing.

Still, the goal of at least partially vaccinating 70% of Americans ages 30 and older has been reached, he said, adding that the administration also is on track to hit the 70% target for ages 27 and older by the Fourth of July weekend.

"This is cause of celebration, and that is exactly what Americans will be able to do on July 4th, celebrate independence from the virus," Zients said.

â–ºWestern Michigan University said it will hold a series of drawings, from August to December, to give away more than $100,000 to students who have been vaccinated against COVID-19

More than 150.46 million Americans have been fully vaccinated – nearly 45.2% of the population, according to the CDC.
