Medical professionals are providing guidance on the optimal timing for seasonal vaccinations as autumn approaches. For influenza, experts warn against vaccinating too early, as protection typically lasts six to eight months and may wane before the end of the flu season. It is generally recommended to consider the flu shot in October or November.

Internal Medicine Specialist Assoc. Prof. Dr. Esra Çokiçli advises that individuals with chronic illnesses should prioritize receiving influenza vaccines, noting that increased viral infections are often linked to cooler weather and more time spent in enclosed environments. Regarding immune support, Çokiçli notes that while many turn to Vitamin C, Vitamin D, and zinc, supplementation should be tailored to individual needs based on blood values. She also noted that Vitamin C is not stored in the body.

As the season progresses, experts have expanded their wellness guidance to include respiratory, ocular, and allergy management. To combat rising viral infections, specialists recommend supporting the immune system through balanced nutrition—including seasonal fruits and vegetables—and regular sleep patterns. 

Eye health is also a growing concern; experts warn that air conditioning and prolonged computer use can cause dryness, while crowded public transport increases the risk of conjunctivitis. Additionally, autumn brings increased allergen exposure, as wind and humidity can disperse pollen from weeds and mold spores from decaying leaves. This may trigger asthma or allergic rhinitis, leading experts to advise careful planning of outdoor activities during windy conditions.
