Travis Kelce recruits mom Donna to star in latest commercial encouraging people to get vaccinated - despite anti-vax Aaron Rodgers mocking Taylor Swift's boyfriend as 'Mr Pfizer'

Travis Kelce and his mom Donna have starred in his latest Pfizer commercial where the NFL star encourages people to get vaccinated.

Kansas City Chiefs tight end Kelce is asked by Donna to help her with a crossword puzzle, to which he jokes that he struggles with spelling - an apparent reference to his old tweets, laden with spelling errors, going viral.

'You know I needed your help with all the spelling classes in English,' Kelce tells her, to which his mom laughs and assures him that 'these will be fairly easy.'

She continues: 'What comes up but never comes down?'

Travis says: 'Well I know you can never get younger, you can only get older. So age?'

Donna congratulates him on being correct and then asks: 'What two things can you never eat for breakfast? 14 letter.'

Travis says: 'You can't eat lunch and dinner, is that 14 letters together?'

Correct again, before Donna tees him up with one last question: 'How can you play defense when you are not on the football field? This one is seven letters.'

Kelce responds: 'I do know this one - vaccine! By getting this season's Covid-19 shot, you can help protect against the disease.'

Kelce has been open about his decision to star in the Pfizer commercials, saying in October: 'I got it because of keeping myself safe, keeping my family safe, the people in this building. So yeah, I stand by it, 1000%,' he said.

His comments came after fellow NFL player Aaron Rodgers of the New York Jets - who is openly anti-vax - called Kelce 'Mr Pfizer' because of his commercials with the company.

'Who knew I'd get into vax wars with Aaron Rodgers, man? Mr. Pfizer against the Johnson and Johnson family over there,' Kelce said, referring to Jets owners Woody and Chris Johnson.

'I'm fully comfortable with him calling me Mr. Pfizer.'
