How does the Flu Shot Work?
Each year, flu season spans from fall to early spring. Because the virus is so widespread and ever-changing, avoiding infection can be nearly immpossible without your annual flu vaccination.
Who Needs a Flu Shot?
If you are one who habitually avoids getting your flu vaccine, consider vaccination to also help prevent exposing others. Many infected individuals may be contagious even if they don’t show physical signs and symptoms of the flu.
