President Joe Biden said the United States has now purchased enough coronavirus vaccine to inoculate 300 million Americans by the end of July. While at the National Institutes of Health on Thursday, Biden announced that the U.S. has secured an additional 200 million vaccine doses from pharmaceutical companies Moderna and Pfizer, increasing the supply by 50 percent and raising the total to 600 million. According to the Washington Post , the Biden administration is acting on options that remain from existing contracts with both companies helping accelerate the delivery time. “Just this afternoon, we signed the final contracts for 100 million more Moderna and one hundred million more Pfizer vaccines ,” the president said. “We’re also able to move up the delivery dates — with an additional 200 million vaccines — to the end of July, faster than we expected.” Related See 'SNL' Turn Covid-19 Vaccine Eligibility Into Game Show Hosted by Dr. Fauci FDA Approves … [Read more...] about Biden: United States Will Have Enough Vaccine Supply for Every American by End of July
