Introduction: Why Flu Vaccination Is Often Misunderstood
Many people believe the flu vaccine is a “one-time” protection. Others skip it if they felt fine last winter.
In reality, the flu virus changes every year, which is why annual flu vaccination is strongly recommended for ongoing protection.
Understanding how flu works can help you make confident, informed decisions for yourself and your family.
What Is the Flu Virus?
Seasonal flu is a contagious respiratory illness caused by influenza viruses.
It spreads easily through coughing, sneezing, and close contact, especially in colder months when people spend more time indoors.
Flu symptoms can vary from mild to severe, particularly for older adults, young children, and those with underlying health conditions.
How Flu Viruses Change Every Year
Flu viruses are constantly changing through a natural process called mutation.
Each year, the virus slightly alters its surface proteins. This means your immune system may not recognise newer strains, even if you had the flu before.
Health experts globally track these changes to predict which flu strains are most likely to circulate each winter.

Why Last Year’s Vaccine Doesn’t Give Full Protection
The annual flu vaccine is updated every year to match the most common circulating strains.
Last year’s vaccine was designed for last year’s virus, not this season’s version.
That is why flu vaccination every year is recommended, even for people who get vaccinated regularly.
According to the NHS, annual vaccination gives the best available protection for the current flu season.
