This is good, but, ck out the first comment under this youtube. It should NOT be all about thimerosal and autism; because there are so many other ingredients in these shots that may cause problems in children, AND adults. And we don’t want a grand study that compares just thimerosal and non-thimerosal vaccines. Are vaccines, especially in the quantities that we inject into our kids, all necessary? In my opinion it compromises our own immune system, and I would prefer to buff up the body the way nature (or God) designed it. I value my choice in the matter, and we can’t lose sight of that human right either.
