Well, that’s a nice bit of insinuation and misinformation.
1. They call up some company and question some call-center woman rather than talking to a person who’s actually an expert on the stuff.
2. They ask if there are any benefits to flu vaccines. The woman says that at worst there appear to be none to the overall population, while quite possibly there are definite benefits. The caller then changes the subject.
3. The caller makes a point of questioning about mercury in the vaccines. What he doesn’t mention is that the vaccines have ethyl-mercury, not methyl-mercury. The latter is the one that causes all sorts of horrible things to people and that they have all the big health warnings about. That hasn’t been a problem with ethyl-mercury at low levels other than minor allergic reactions such as itching and swelling where the shot was given (it can cause problems at excessive doses, yes, but so does anything else, and those doses are far beyond what you would get in a thousand vaccinations at once). There were some concerns raised a few years ago that infants couldn’t rid their bodies of ethyl-mercury properly, and the FDA had the ethyl-mercury preservatives removed from most vaccines just in case. Later testing found that infants can handle ethyl-mercury just fine.
