With the holiday season fast approaching, so too does the annual flu season, a time when influenza viruses spread more readily among communities. According to the Centers for Disease Control and Prevention, February historically marks the peak of flu activity, but the season can begin as early as October. To reduce the risk of contracting the flu, physician Matthew Heller, D.O., an associate professor of family medicine at New York Institute of Technology College of Osteopathic Medicine, strongly recommends getting a flu shot. He notes that anyone over the age of 6 months should be vaccinated annually, though individuals should consult their physician about potential exceptions.
The flu vaccine works by stimulating the body to develop antibodies that provide protection against the virus. Even in seasons when the vaccine is less effective due to viral mutations, it still offers significant benefits. Vaccination reduces the severity of symptoms and complications if a vaccinated person does contract the flu. It also protects against hospitalizations and deaths and lessens the likelihood of influenza-associated outpatient visits across all age groups. Importantly, Heller emphasizes that the vaccines cannot cause the flu itself, as they are made from inactivated viruses or components.
Timing is crucial: 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. People typically become symptomatic a few days after exposure and are contagious during that period. Symptoms can last about a week. While most individuals can recover at home with rest and fluids, those in high-risk groups—such as adults 65 and older, young children, pregnant women, and people with chronic health conditions—should contact a physician if they suspect the flu.
Beyond vaccination, Heller advises other preventive measures: frequent hand washing, using hand sanitizer, sanitizing high-traffic surfaces, avoiding touching the face and large crowds, and sneezing into a tissue or the elbow. These practices help curb the spread of the virus.
Heller stresses the broader impact of vaccination: “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.” His expertise is part of New York Tech’s commitment to addressing real-world health challenges. For more information, visit nyit.edu.
