You’ve never heard of long flu? It’s quite well known - you probably know it as post viral fatigue, & ME and chronic fatigue syndrome are all thought to be triggered by viral infections (in the majority of cases, although I think there can be other triggers). You hear of a lot of cases triggered by flu, as it’s one of the most common viral infections around. You allude to it in your previous post so I’m sure you’re aware of it.
As for the numbers, no, I’m clear on the point I made. If you choose not to think it’s important, no problem, we’ll agree to disagree there.
As for the rest of your post… Yes, there absolutely needs to be support for people who have complications after the vaccine. Like the example with your sister in law, though, there will be some who have some illness or weird symptoms after the vaccine, and attribute it to the vaccine, only to find out it was unconnected, as in your sister in law’s case with her contraception and long covid. (Also sympathy to her, glad she got it sorted out.)
Does this mean all people who report vaccine side effects should be ignored? Does it mean all people who report long covid should be ignored? Absolutely not. There needs to be space for both. From what I’ve seen, with my unwanted specialist knowledge, the numbers of cases of long covid lasting over 1 year in children are high, far more than there are cases of vaccine damage. The numbers of PIMS cases are higher than cases of vaccine damage in children. That’s what I’m basing my views on. I’ve seen first both hand so it really hits home.
That doesn’t mean you’re wrong to feel the way you do, you’ve just been exposed to different information. And I appreciate it’s frustrating when you don’t feel heard by the “other side”.
