- We mentioned this past summer that John Cena filmed a commercial for a campaign by the Gates Foundation and Rotary International to end polio. The spot was released today on Bill Gates' official Twitter account, which you can watch above. In the video, Cena is shown knowing everything, from playing Chess to speaking Mandarin. However, the one thing he doesn't know about is polio eradication. Cena was educated on the subject, being told that while there is no cure, the virus can be prevented by vaccines. The Gates Foundation and Rotary International have pledged $450 million to end the disease.
