Vaccine requirements are a completely unfair, apartheid-like system. Especially since not everyone has access to vaccines.
But even more to the point I see, vaccines are designed to primarily protect you ... not to protect those around you. As such, they are tested for preventing symptoms ... not infection or transmission. The latter two are what we really need to focus on in social environments, hence things like PCR tests. And while vaccines do lower the incidents of both, they aren't a replacement for testing. It's merely cheap and lazy shorthand to substitute vaccines for infection testing.
Even more dangerous, relying on vaccines as your lazy, only strategy is like dead-bolting your front door while leaving your windows open. Vaccines will be breached more by variants over time, and if you have only one line of defense you're kinda screwed once that breaks down.

Long-term, yes, we don't have the data for that. But a focus on that can dismiss how ridiculously rigorous it is to get something approved in the first place. The first clinical trials are all about safety. If they make it past that, there are trials for efficacy.
Point is that we have hundreds of millions of data points suggesting things have been quite thorough statistically. We do have historical examples like thalidomide, which took five years to detect what was wrong. But that's hardly a comparison because a) it had a mere fraction of the testing and distribution, b) it was applied for different conditions other than the original ones for which it was approved, and c) clinical trial testing became immensely more restrictive after that disaster.
