The protests in Germany have been similar to those in the US, they are mostly by extremists (both on the left and the right) and by conspiraloons. I see no evidence here of vaccines being rushed through, there is no sign of a vaccine for Covid 19. Germany has just agreed to spent a lot of money on research into a vaccine/treatment, that's all .
Immunisation has been made compulsory, this was mainly in regard to measles and i'm all for it. There is a dangerous culture of homeopathy and alternative medicine here in Germany, it's far more mainstream than in the UK, so with that you'll also get more anti-vaxers kicking up a fuss. There have been violent assaults on journalists just doing their job at several of these protests, so that should tell you something about the participants.
