Marshfield Clinic Health System: Flu vaccinations now available

MARSHFIELD – 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. During the most recent flu season, it was estimated there were more than 300,000 people hospitalized and more than 20,000 people died from the flu in the United States.

The best way to prevent flu is by getting a flu vaccine each year. Studies have shown that vaccination reduces the risk of hospitalization and death from influenza.

The 2023-24 vaccine was a good match for circulating viruses and in preventing hospitalizations. The 2024-25 vaccine has been updated to protect against the three most common strains of flu.

In the northern hemisphere, most of the time flu activity peaks between December and March, but activity can last as late as May.

“Everyone should get a flu vaccine this year, preferably before November,” said Dr. Edward Belongia, a scientist at the Marshfield Clinic Research Institute who studies vaccine safety and effectiveness. “Flu seasons are unpredictable in terms of timing and severity, and in some years we see substantial flu activity in November. It takes a couple weeks for your immune system to respond and generate protection after vaccination.”

Some children will need two doses of vaccine to be protected. They should start the vaccination process in September or October, because the two doses must be given at least four weeks apart.

This year, the Health System will offer FluZONE for patients ages six months and older and FluZONE High Dose for patients ages 65 years and older and immunocompromised patients 18 years and older. The high dose vaccine may provide a greater level of protection for patients at higher risk for flu complications.

Vaccination is especially important for older adults and young children who have the highest risk of developing flu complications. These can include bacterial pneumonia, ear infections, sinus infections and worsening of chronic medical conditions, such as heart failure, asthma or diabetes.

“Receiving the vaccine doesn’t guarantee you won’t get the flu, but the vaccines will help protect against serious flu illness or complications,” said Dr. Belongia.

It is easy and convenient to schedule your flu vaccine online through your My Marshfield Clinic account. Visit marshfieldclinic.org/flu for more information and appointment options.

The Health System offers flu vaccines at primary care locations during flu season. Flu vaccine appointments are preferred, but our locations also offer flu clinics periodically throughout the season to make it convenient for patients and community members to stop in for a flu vaccine.
