President Biden is in Portage, Michigan, where he is visiting one of the three manufacturing plants where Pfizer's Covid-19 vaccine is produced, according the White House.
The President is touring the facility and meeting with workers who are helping manufacture the vaccine. Biden will then deliver remarks.
Pfizer's vaccine won the FDA's Emergency Use Authorization in December, and is being delivered to millions of people in the US and UK.
Both vaccines on the US market — developed by Pfizer-BioNTech and Moderna — require two doses to reach about 95% efficacy, and the second doses were intended to be administered 21 days and 28 days after the first, respectively.
Biden addressed his administration's vaccine goals on Tuesday during a CNN town hall in Milwaukee, announcing that 600 million doses of vaccine will be available by the end of July.
