As the holiday season approaches, so does the annual flu season, a time when influenza viruses spread widely, causing illness, hospitalizations, and even deaths. According to the Centers for Disease Control and Prevention, February historically marks the peak of flu activity, making now the critical time to take preventive measures. Dr. Matthew Heller, an associate professor of family medicine at New York Institute of Technology College of Osteopathic Medicine, emphasizes that the most effective way to reduce the risk of contracting the flu is to get vaccinated annually. "Anyone over the age of 6 months should be vaccinated," Heller advises, "but always talk to your physician about potential exceptions and whether the vaccine is appropriate for you."
The flu vaccine works by stimulating the body to produce antibodies that provide protection against the influenza virus. Even in seasons when the vaccine is less effective due to virus mutations, it still offers significant benefits. Research shows that vaccination reduces the risk of flu-associated hospitalizations and deaths and lowers the likelihood of outpatient visits across all age groups. Importantly, Heller clarifies that the vaccine cannot cause the flu, as it is developed from inactivated or weakened viruses.
Timing is crucial. It takes about two weeks for the body to build full immunity after vaccination, so getting vaccinated early in the season is essential. The flu's symptoms—fever, chills, body aches, cough, headache, and fatigue—typically appear a few days after exposure, and individuals can spread the virus before they even feel sick. While most healthy people recover at home with rest and fluids, those in high-risk groups, including adults 65 and older, young children, pregnant women, and individuals with chronic health conditions, should seek medical advice promptly if they suspect infection.
Beyond vaccination, Heller recommends simple yet effective preventive measures: frequent hand washing, using hand sanitizer, sanitizing high-touch surfaces, avoiding touching the face, steering clear of large crowds, and sneezing into a tissue or elbow. These actions can significantly reduce the spread of the virus.
The impact of the flu extends beyond personal health. "The flu spreads easily from person to person," Heller stresses. "Getting the flu vaccine not only protects you but also protects those around you, especially vulnerable populations. By setting an example, others will follow." This collective responsibility is vital in mitigating the burden of flu each season.
As part of New York Institute of Technology's commitment to addressing real-world health challenges, Heller's guidance underscores the importance of proactive health measures. For more information on the flu and vaccination, visit nyit.edu.
