Very prevalent unfortunately. That's why we probably won't reach herd immunity. Lots of crazy conspiracy theorists around too. One "famous" german pop singer posted today, that all vaccinated people will be dead by September. Unfortunately he has a lot of followers and fans who probably believe bullshit like that. Also, you remember 99 Red Balloons singer Nena? She's turned into a proper nutcase as well and encourages her fans to ignore all hygiene concepts etc. But she was always crazy. So it's not that big of a surprise.
