No, because again, you take the vaccine, it causes an immune response, and then it leaves your system. Even if you then take it again a year later. It's not like a drug that you're regularly taking, which remains in your system. What would change my mind is if I saw vaccinologists explaining a mechanism by which a vaccine could cause long-term side effects, rather than the opposite.

The flu vaccine is still called a vaccine and it’s delivered yearly and while not required is highly recommended indefinitely.

Why would this be any different?
