I hear people say that, but is there research backing it up? I'm a bit dubious because inevitability is a common fall-back position in public affairs, similar to climate change deniers saying that climate change is inevitable so we just have to learn to adjust. They still get what they want, and try to create despair in their opponents.
It's gone endemic, the inevitability is on par with the common cold; you're almost certainly going to get exposed to some variant of it.
Plus AIUI Omicron has demonstrated recombinant replication, which means we're playing a flu-like cat and mouse game with the vaccines. Nobody in their right mind would argue we have any hope of effectively vaccinating everyone against influenza.
