ROCHESTER, Minn. - A flu shot is a vaccination made of inactive flu strains.
By getting a shot of inactive flu strains, the body builds an immunity towards the strain which helps fight off the sickness.
But getting a shot years ago doesn't mean much for this upcoming flu season, which peaks around February.
"You should get a flu shot every single year, because they're different strains. That way you have the most current strains that they're thinking are going to be the problems for the season," Audra Rinard, pharmacy manager at Hy-Vee, said.
She said a flu vaccine helps more than the person receiving the shot.
"By getting the vaccine you're not only protecting yourself but it's that herd immunity. It's protecting those around you who are maybe amino compromised and are actually more at risk of the complications of the flu," she said.
The very young and very old are most susceptible to getting the flu.
Rinard said a numbing spray before the shot helps ease any physical pain.
Health coverage can also help ease some of the financial pain.
"It's seen as a preventative. So typically there's no cost to the vaccine," she said.
