Is that not then a reason to get better sources? There's a reason why sources like Fox News aren't warmly welcomed here while .edu sites generally pass the source credibility test here. If it looks more like an advertisement, if it uses bad sources, if it clearly contradicts what you can see when you look around (in this case, we aren't seeing polo, except where the vaccines are not being used), contradicts what has become a highly rigorous area of study because people still doubt, and is based on lies, it isn't good. The thing with autism, for example, was started by a guy who did not do any research, he did not set up any experiment, he only put in extremely limited effort into gathering data, he didn't even compare his findings to the general population of those who have the vaccine and those who don't. There are some risks involved, and some people do have bad reactions. No one is denying that. But, I for one am glad that polo was not a part of my childhood and I don't know anyone with it. I'm sure I'm not the only one who feels this way. And, as far as I know, we have more people on this forum who are at risk around those without the vaccines should that person be carrying than there are members who have had a bad reaction to the vaccines.
