While the fever declines on the second or third day of the illness, full recovery may take up to 6 weeks. While most people recover fully, influenza may lead to more severe and life-threatening illnesses, such as pneumonia, resulting in hospitalization and even death. However, vaccination is the only prevention measure that has been proven to reduce mortality rates caused by influenza. And while a good diet, vitamins and exercise all contribute to your general health, they won't protect you from the influenza virus. Vaccination every fall can.
Studies show that immunization is effective in preventing the flu in all segments of the population.
Furthermore, it reduces the seriousness of the disease should you contract it. Most commonly, mild soreness at the vaccination site is the only side effect. Less common are headaches and muscle pains. As a precaution, you will be asked to remain at the clinic for 20 minutes following vaccination. If you are allergic to eggs then a flu vaccine may not be for you.
