As the holiday season approaches, so does the peak of flu activity, which historically occurs in February, according to data from the Centers for Disease Control and Prevention. With the virus spreading easily from person to person, the importance of vaccination cannot be overstated. Dr. Matthew Heller, an associate professor of family medicine at New York Institute of Technology College of Osteopathic Medicine, urges everyone over the age of 6 months to get an annual flu shot, unless their physician advises otherwise.
The flu vaccine works by stimulating the body to produce antibodies that offer protection against the influenza virus. While no vaccine is 100% effective, Dr. Heller points out that even in seasons when the vaccine is less matched to circulating strains, it still reduces the risk of severe illness, hospitalization, and death. "The way flu vaccines are developed makes them unable to cause the illness itself," he emphasizes, addressing a common misconception. Instead, vaccinated individuals who do contract the flu typically experience milder symptoms and fewer complications.
Timing is critical. It takes about two weeks after vaccination for the body to build full immunity, so getting vaccinated early in the season is essential. The CDC recommends vaccination by the end of October, but getting the shot later can still provide protection, as flu activity often peaks in February.
Flu symptoms include fever, chills, body aches, cough, headache, and fatigue, which can last about a week. Individuals become contagious a few days after exposure, often before symptoms appear, making it easy to spread the virus unknowingly. For most people, recovering at home with rest and fluids is sufficient, but those in high-risk groups—adults 65 and older, young children, pregnant women, and individuals with chronic health conditions—should contact a physician promptly if they develop flu-like symptoms.
Beyond vaccination, Dr. Heller advises preventive measures such as frequent hand washing, using hand sanitizer, disinfecting commonly touched surfaces, avoiding touching the face, steering clear of large crowds, and sneezing into a tissue or elbow. These practices not only protect oneself but also reduce the transmission of the virus to others, particularly those who are more vulnerable.
The broader implications of flu vaccination extend beyond personal health. Widespread vaccination helps establish herd immunity, which shields those who cannot be vaccinated due to medical reasons. Dr. Heller stresses, "Getting the flu vaccine will not only protect you but will also protect all those around you. By setting the example, others will follow." This collective responsibility is vital, as influenza places a significant burden on healthcare systems each year, leading to numerous outpatient visits, hospitalizations, and even deaths.
In an era where public health challenges are increasingly complex, staying informed and proactive is key. Dr. Heller is among many experts at New York Institute of Technology working to address such real-world issues. To learn more about their initiatives, visit nyit.edu.
