Influenza viruses are constantly changing. This is not a slow, predictable process; they undergo small, continuous mutations. Think of it like a new coat of paint and a new hairstyle every year. While the virus might be fundamentally the same, these subtle changes are enough to make it look "unrecognisable" to the antibodies your body developed from last year's vaccine.
Each year, global health organisations like the World Health Organization (WHO) work tirelessly to predict which strains of the flu virus are most likely to be circulating in the upcoming season. The new flu vaccine is then specifically formulated to protect against these predicted strains. Getting last year's vaccine wouldn't provide you with the necessary protection against the new, slightly different viruses in circulation this year.
Even if the flu virus didn't change at all, the protection you get from a flu jab is not permanent. The level of antibodies your body produces in response to the vaccine will naturally decline over time. By the time the next flu season arrives, your immunity from the previous year may have dropped to a level where you are no longer sufficiently protected.
Getting your flu jab annually acts as a vital booster, giving your immune system the fresh instructions it needs to fight off the latest flu strains. It's an essential part of your winter health routine, just like wearing a coat on a cold day.
Don't leave yourself vulnerable this winter. Getting your annual flu jab is the best way to protect yourself and your loved ones from a potentially serious illness.
