Since its release last Tuesday, the pro-vaccine anthem #VaxThatThangUp, a remix to rapper Juvenile's '90s hit "Back That Thang Up," has garnered nearly 3 million views on YouTube and widespread attention on social media as the nation aims to recover from the Covid-19 pandemic.

The viral video, that serves as a commercial for the BLK dating app, came about from some very unlikely partnerships: The White House, Shaquille O'Neal's ad agency Majority and BLK, a dating app that is trying to establish itself as the destination of choice for Black singles.
