Flu Season Approaches: Experts Warn of Common Immunization Mistakes

NEW YORK, NY — As flu season approaches, health experts are urging Americans to prepare for the return of respiratory viruses. Dr. David Hirsch, an infectious disease specialist at Northwell Health, identified common immunization errors and shared tips to boost immunity against the flu.

Hirsch emphasized that the flu shot offers optimal protection in the first two months following vaccination. He stated, “The protection from the flu shot is best in the first two months after vaccination, but then it decreases.” Therefore, delaying the flu shot could heighten risks of severe symptoms or contracting the virus.

The ideal time to receive the flu vaccine is two weeks before flu season begins, which typically peaks in late November or December. Hirsch recommends getting vaccinated in late October or early November, though flu outbreaks may occur as early as September.

Hirsch also pointed out that everyone aged 6 months and older should receive a flu shot annually. He cautioned that those on steroids like prednisone should avoid taking them for at least two weeks prior to vaccination, as they may diminish the shot’s effectiveness.

Research indicated that individuals who received steroid injections shortly before their flu vaccine were at a 52% higher risk of contracting the virus. Additionally, taking painkillers like Tylenol before getting vaccinated may weaken immune response, although they can be taken afterward if needed.

Physical activity plays a critical role in vaccine effectiveness. Studies suggest that individuals who exercise for 90 minutes post-vaccination generate a stronger antibody response compared to sedentary individuals. Maintaining a healthy lifestyle, including nutrition rich in probiotics and fiber, can also enhance immune response.

In light of the significance of community immunity, pharmacies and clinics nationwide are now offering flu vaccines. Dr. Whitney Lane, a pharmacy manager at Hannaford Supermarkets, reiterated, “Getting your flu shot is the No. 1 way to help get you protected against influenza, help protect your friends and family, help decrease the spread.”

As flu season is anticipated to be severe, protection is especially crucial for vulnerable populations, including young children, older adults, and immunocompromised individuals. Experts agree that timely vaccination offers the best defense against influenza complications.
