You want to do everything possible to make sure your family stays healthy and getting your flu shot is one of the best ways to do that.

Vaccine is available for both adults and children on a first-come, first-served basis. Consent forms can be downloaded online or completed at the time of service.

According to the CDC, on average, more than 200,000 people in the United States are hospitalized each year and 49,000 deaths occur for illnesses associated with seasonal influenza virus infections. Vaccination is the most important step in protecting yourself against the flu.

For more information on why it is important to vaccinate babies and young children, visit our Pediatric Flu Vaccination page here.
