I agree. The virus (the flu) will continue to mutate; and it will stay ahead of the vaccines. The people that have taken vaccines will serve as virus test beds: selecting for virus that can overcome the immune response; selecting for more virulent forms s. There will be an arms race between this virus and the vaccines; new vaccine variations are released every few months to stay on top of the mutating virus.

We have “super bugs” in our hospitals; bacteria which is resistant to all our antibiotics. This vaccine regiment will do the same, except for a virus.
