Surprising that the conspiracy theorists haven't got to work on this one as well. Perhaps because it's so little known. It's just a vaccination. It works, as they pretty much all do, with rare exceptions. Much like the COVID ones, if only the self publicists, the misinformationists, the political footballers, could have left those alone too. Having a vaccination against various diseases is a small thing in itself, but can improve people's lives so much, yet the effect is that you don't get something that might make your life miserable, or shorten it, or end it. Yet people say, well, I might never have got it anyway, and that could be true too as it's hard to prove a negative. Still, if a vaccination is available it stacks the odds in your favour, so surely better to have it than not, especially if it's free.
