Not gonna get into the efficacy of vaccines (I'm NOT an anti-vaxxer)

I don't bother with the flu shot personally because my immune system is still a beast (I never get sick).
What I found...amusing(?) was a commercial I saw yesterday for some new flu prescription pill. You get the flu and you take this pill to make it go away. In the ad, it says "Take just 1 dose a day, rest, in a few days you'll feel better." But...doesn't the flu generally go away within a few days anyway?
