Biden's goal equates to delivering at least the first shot to 181 million adults and fully vaccinating 160 million.
"I've worked very hard to make sure we have over 600 million doses of vaccine", Biden said. During a press briefing, a senior Biden aide said the administration estimated that reaching each goal would require administering about another 100 million doses to adults in the next two months, roughly three-quarters of the current pace.
Biden also added Wednesday that his administration is working with retail chains and sports leagues to offer deals and promotions for people who get vaccinated in the hopes making vaccinations more "fun".
