RE: yet ANOTHER adjuvanated vaccine, that is, one that contains bizarre chemicals whose sole purpose is to artificially over hyper-stimulate the immune system because the native vaccine itself is too weak to do the job without said adjuvants ...
OK, here’s a question - what makes the Polio and Small Pox vaccine so different? Why do they last almost a lifetime while these Covid-19 vaccines do not guarantee that?
Antigenic drift and shift. The longer the antigen(s) remain(s) stable, the longer the vaccine is effective. For some things, this may be a year or less. For some, it may be three or five years. For some, it may be a human lifetime.
This is partially down to how prone to errors the replication process is for the particular pathogen and partially down to how stable the protein(s) making up the antigen is/are. If they happen to refold easily enough, that structural change can present problems for dendritic recognition.

Someone may give you a better answer, but I’m pretty sure it is not the “vaccines” but the nature of the diseases.
I don’t think polio, smallpox, measles, etc. are caused by viruses. So those diseases don’t change/mutate over time. Covid is a virus, like the flu. You know how they change the flu shot ever year, because the flu is not the same from year to year. And those shots are never 100% effective I don’t think.
My understanding is that calling ANY of these treatements “vaccines” is a complete misnomer. We should be calling them covid “shots”.

there are two factors regarding the longevity of immunity from vaccination:
1. The first factor is whether the bugs mutate or not; polio, tetanus, rabies, small pox, and a whole slew of bugs don’t mutate, so annual vaccinations are not required as is the case, with bugslie influenza, which mutate wildly ...
2. The second factor is how long immunity persists after infection or vaccination: some immunity is persistent for a lifetime, but immunity fades over time for other infections as the immune system loses its memory of previous infection/vaccination. Polio vaccination provides lifetime immunity for example, but tetanus requires re-vaccination every ten years ...
thus a bug that doesn’t mutate and which the immune system doesn’t forget requires only a single infection/vaccination to provide lifetime immunity, but bugs that mutate or the immune system knowledge fades, requires either a NEW vaccine or a booster vaccination of the original vaccine ...
btw, there’s another wrinkle in all of this, namely that the quick and dirty experimental vaccines offer extremely limited immunity due to the way they’re constructed compared to conventional vaccines made from weakened or killed whole-bugs ...
whole-bug vaccines trigger the immune system to make thousands of DIFFERENT antibodies, whereas the current crop of Q&D covid vaccines are built to trigger only a tiny number of different antibodies, thus conventional vaccines are more prone to offer protection against bug mutation, whereas the Q&D vaccines are almost guaranteed to require a NEW vaccine and vaccination annually, thus providing tens of billions of annual profits to Big Pharm in perpetuity paid for by we taxpayers ...
