SmartShots is offering a variety of shots, including the flu vaccine for $5.
"This is the perfect time to get them. The flu is much stronger than what they thought it was going to be. It's more widespread and they're $5. Who can resist that? Come down, get your $5 flu shot and be protected for the rest of the flu season," said Lauren Curbown, with SmartShots.
Joe Mitchell from The Biggest Loser is at The Healthy Living Expo with Fort Sanders Health and Fitness.
He lost 133 lbs. on the TV show and has lost even more weight since.
"There's not an end point. A lot of people think when you have your finale on The Biggest Loser, you're done, and it's really not. It's about changing your lifestyle. It's about making little changes that you can live with," Mitchell said.
The Healthy Living Expo is open until 3 p.m. on Friday and Saturday from 9 a.m. to 5 p.m.
