Patrick Mahomes says he’s fully vaccinated … telling reporters Monday he took the shots in the arm to try to help ensure his newborn baby daughter stays healthy.

“To me, it was more of a personal decision with having a baby girl and knowing that I was going to be around people,” the NFL superstar said.

“I wanted to make sure I could do whatever I could to help keep her healthy.”

Mahomes and his fiancee, Brittany Matthews, welcomed little Sterling Skye Mahomes back in late February … and Patrick clearly didn’t wrestle too much with the decision to get vaccinated as a new dad.

But, Patrick emphasized the choice to get the shots is “a personal decision for everybody.”

“Whatever you believe,” the 25-year-old said, “I think you can do whatever that is.”

As for how fatherhood is going, Patrick said the last two months have been a whirlwind … explaining, “I’ve had to learn a lot there, probably more than I’ve learned in my entire life ’til now of how to take care of a baby and raise a little baby girl.”
