Former presidents Barack Obama, George W. Bush, Bill Clinton and Jimmy Carter and their first ladies came together for a series of ads promoting the COVID-19 vaccines. One video shows all of them getting the shot.

In a release, Bush highlighted the work of the "dedicated scientists and researchers" who developed safe vaccines quickly, while Clinton noted that vaccination will "bring us all one step closer to ending this pandemic."

Obama acknowledged the "immeasurable toll" the pandemic has taken on families, while the 96-year-old Carter said vaccines and other public health measures are the key to him seeing his children, grandchildren and great-grandchildren again.

The second ad brings Obama, Bush and Clinton together in Arlington National Cemetery in Virginia, where they emphasize that the vaccines will soon be universally available. In the US, vaccines from Pfizer, Moderna and Johnson & Johnson have been administered to high-risk groups first as production starts to ramp up.

During a Healthline town hall reflecting on one year of COVID-19, Paula Green-Smith, a Detroit public health professional, stressed the importance of having trusted messengers deliver information on the coronavirus as well as other community health issues. 

"You've got to have trusted messengers, people that other people will listen to," said Green-Smith during the town hall on Thursday.
