There's not any doubt that the vaccine helps some people or that it's way more deadly than any other vaccine since variolation was a thing. The question is really just how effective and how deadly. Who should have gotten it and who shouldn't have.

Figure 2 shows the vaccine delaying infection by 6 months, but not preventing infection. Figure 3 shows older non-infected unvaccinated with 0.88 survival at 26 weeks vs 0.96 for vaccinated - so 3x more likely to die from not-covid.

These were people who got a test for some reason so maybe there was something wrong, but still that's a pretty huge difference and it shows that you can get a big result from something besides what you thought you were measuring.

The thing about Sweden is I'm sure you've seen the Swedish bus stop meme. But yeah they came out well.
