The symptoms of strain A are typically more severe than the symptoms of strain B. Each year, the virus undergoes small changes, and approximately every 20 years, its structure undergoes a major change. Annual flu shots are recommended due to these constant changes. Each year scientists develop vaccines based on those annual changes.
