The influenza virus is remarkably adaptable, which is why we face a new flu season every year. Understanding this can help you appreciate the importance of annual vaccination.
Why the Flu Keeps Changing
Flu viruses constantly mutate, creating new strains. This is why last year's immunity—whether from infection or vaccination—may not protect you this year.
The Importance of Annual Vaccination
Each year's flu vaccine is designed to match circulating strains. Getting vaccinated protects you and helps prevent spread to vulnerable populations like infants and elderly adults.
Additional Protection Strategies
Beyond vaccination, practice good hand hygiene, avoid close contact with sick individuals, stay home when ill, and maintain a healthy lifestyle to support your immune system.
