Marshfield Clinic Health System is now offering influenza (flu) vaccinations at all primary care locations throughout Wisconsin.
Influenza, commonly referred to as “flu,” is a contagious respiratory illness caused by influenza viruses that infect the nose, throat, and sometimes the lungs. It can cause mild to severe illness, and at times can lead to death.
While influenza viruses circulate year-round, most of the time flu activity peaks between December and March, but activity can last as late as May. CLICK HERE FOR MORE INFO AND LOCAL FLU SHOT CLINIC LOCATIONS.
