5 Reasons To Get A Flu Shot Every Year

Every year, new flu vaccines are created and released to keep up with continually adapting flu viruses. These flu viruses have such rapid evolution that a vaccine from last year may not be able to protect against a virus this year. Once vaccinated, the immune system will react by producing antibodies, protecting the patient from viruses.

It’s quite possible to catch the season's flu strain if the vaccine is not received yearly. Influenza can leave patients sick in bed for a week or worse, wind up hospitalized. Influenza circulates on a worldwide scale and can affect anyone.
