Countries had different rates of RNA vaccination (africa, east vs west in EU). There is correlation with long covid.

We could have a serious investigation, matching different batches (that vary in quality) to patients, and estimate side effects of each batch. But that was never done.

> The signal was so clear even though it was something like 1 in 50,000 people who had a problem.

Right, maybe the clear signal was "people end in hospital right after shot? Kind of hard to ignore.

> giant resurgence of measles now because those people are so large in number and so influential

Perhaps there are other factors? Like huge stream of new people who never had medical check?

> Long covid is far more prevalent in those populations than anywhere else

Some countries never had RNA vaccines, no long covid.

> insane pivot with omicron. Way too many mutations at once for any vaccine to accommodate.

I was told to get yet another shot, because old vaccine was effective against omicron. You sound like one of those vax deniers!
