Final answer:
There are several reasons why you should get a flu vaccine every year: protection against new strains, prevention of complications, and reducing the spread of flu.
Step-by-step explanation:
There are several reasons why you should get a flu vaccine every year:
- Protection against new strains: Influenza viruses have a high mutation rate, leading to the emergence of new strains. The annual flu vaccine is designed to protect against the most prevalent strains for that year.
- Prevention of complications: The flu vaccine is especially important for individuals at high risk of developing serious complications if they get sick with the flu, such as those with certain medical conditions or older adults.
- Reducing the spread of flu: Getting vaccinated can help prevent the spread of the flu to others, particularly those who are unable to receive the vaccine themselves.
