As holiday celebrations approach, so does the peak of flu season. According to the Centers for Disease Control and Prevention, February historically marks the highest flu activity. To reduce the risk of contracting the virus, Dr. Matthew Heller, an associate professor of family medicine at New York Institute of Technology College of Osteopathic Medicine, stresses the importance of getting a flu shot. He advises that everyone over six months of age should be vaccinated annually, but notes that individuals should consult their physician to determine if the vaccine is appropriate for them.
The flu vaccine works by stimulating the body to produce antibodies that protect against the influenza virus. Dr. Heller explains that even in seasons when the vaccine’s effectiveness is reduced due to viral mutations, it still provides crucial benefits. Vaccination can lessen the severity of symptoms and reduce the risk of complications, hospitalizations, and outpatient visits across all age groups. Importantly, he emphasizes that the vaccine cannot cause the flu because of how it is developed.
It is vital to get vaccinated early, as it takes about two weeks for the body to build full immunity. Flu symptoms, which include fever, chills, body aches, cough, headache, and fatigue, typically appear a few days after exposure, and an infected person can spread the virus before symptoms develop. Symptoms usually last about a week.
While most healthy individuals can recover at home with rest and fluids, those in high-risk groups—such as adults over 65, young children, pregnant women, and people with chronic health conditions—should contact a physician if they suspect they have the flu.
Beyond vaccination, Dr. Heller recommends frequent handwashing, using hand sanitizer, cleaning high-touch surfaces, avoiding touching the face, and avoiding large crowds. Sneezing into a tissue or elbow also helps prevent the spread of the virus.
“The flu spreads easily from person to person,” Dr. Heller warns. “Getting the flu vaccine will not only protect you but also those around you. By setting an example, others will follow.”
