On Friday, March 12, 2021, The Associated Press reported on stories circulating online incorrectly asserting the $1.9 trillion COVID-19 relief bill awards a $25 million bonus to members of the House of Representatives. There are several passages that cite $25 million in funding, but no mention of congressional pay raises or bonuses. (AP Photo/J. Scott Applewhite)

FILE - In this Wednesday, Sept. 2, 2020 file photo, blood samples from volunteers participating in the last-stage testing of the COVID-19 vaccine by Moderna and the National Institutes wait to be processed in a lab at the University of Miami Miller School of Medicine in Miami. Creating vaccines and properly testing them less than a year after the world discovered a never-before-seen disease is incredible. But the two U.S. frontrunners are made in a way that promises speedier development may become the norm -- especially if they prove to work long-term as well as they have in early testing.
