Question) How long does immunity last after getting a flu shot?
2025.10.25 22:32
The daily temperature range has been extreme lately, and the weather has suddenly gotten colder, so I've been seeing a lot of people with colds around me. I heard you can get a free flu shot this time. Did you all get it?
I'm usually healthy, so even if I catch a cold, it's mild. But this time, I'm thinking of getting a flu shot in advance.
How long will immunity last after getting a flu shot?
Also, can the effectiveness of the flu shot vary depending on your health condition?
