With the holiday season approaching, so too does the peak of flu activity, historically hitting its highest point in February, according to data from the Centers for Disease Control and Prevention. In an effort 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, strongly recommends that everyone over the age of 6 months receive an annual flu shot. However, he advises, "Always talk to your physician about potential exceptions and find out whether the flu vaccine is appropriate for you."
The flu, or influenza, is a viral respiratory illness that spreads easily from person to person, particularly in crowded settings. Dr. Heller explains that the vaccine works by prompting the body to develop antibodies that fight off the virus. Even when the vaccine is not perfectly matched to circulating strains due to mutations, it still offers significant protection against hospitalizations, deaths, and reduces outpatient visits across all age groups. Importantly, he notes that the vaccine cannot cause the flu itself, as it is made from inactivated viruses or components.
Timing is critical: it takes about two weeks after vaccination for the body to build full immunity. Therefore, getting vaccinated early in the season is essential. Flu symptoms include fever, chills, body aches, cough, headache, and fatigue, typically appearing a few days after exposure and lasting about a week. Most healthy individuals can recover at home with rest and fluids, but those in high-risk groups—adults 65 and older, 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 emphasizes other preventive measures: frequent hand washing, using hand sanitizer, cleaning high-traffic surfaces, avoiding touching the face, steering clear of large crowds, and sneezing into a tissue or elbow. He underscores the collective responsibility: "The flu spreads easily from person to person. Remember that getting the flu vaccine will not only protect you but will also protect all those around you. By setting the example, others will follow."
As a faculty member at New York Institute of Technology, Dr. Heller is part of a broader effort to apply academic expertise to real-world health challenges.
