There is a big problem with groups based solely by age; in truth, if you are metabolically unhealthy, either by diagnosis or have a suspicion you might be (if you're living a typical western lifestyle, chances are you are - 88% of american adults are metabolically unhealthy, look it up), and unwilling to make the necessary lifestyle changes, there is a possibility that vaccination might benefit you, but even there there is a spectrum, with factors increasing such as taking medication, being chronically stressed/depressed, not sleeping well, etc.
All in all, what I wanted to say is that the message to the masses is intentionally or not simplified, and it hides the nuances that everyone should apply to themselves. In my case, I have made drastic changes to better my health after a diagnosis of severe autoimmune illness more than a decade ago, and today am in much better health than I was then, so I have no benefit to expect from taking the vaccine.
