It also doesn't help that the H1N1 vaccines came too late to do much good: while Pandermix was just one of many vaccines, and the only one I'm aware of known to cause problems, in most places they hardly made a difference because infections had already peaked by the time they were distributed widely. Eg here in Canada, I've seen estimates that vaccines reduced H1N1 deaths by about 5% at best. H1N1 still infected around 20-30% of the entire world population, and Canada was no different. A significant % of people were already immune, so natural herd immunity is the main thing that stopped it. Given how fast COVID-19 appears to be spreading even in places with strict lockdown, I won't be surprised if it turns out that vaccines don't actually make much difference with it either.
