I've found very few MDs who have any kind of listening skills. I've known some brilliant ones. But many of them are shills for the drug companies, pushing unnecessary drugs and just all-around being ineffective. We're told to revere doctors, but the reality is that MDs are not scientists -- they're technicians, and often not terribly skilled ones. These facts are not lost on their patents. People just don't trust doctors. Vaccines are just one more dubious thing that MDs push on us.
This distrust of the medical profession totally understandable, and you shouldn't call people morons for feeling this way. Most people are not scientists who can do their own research. Their only source of information is these doctors they don't like. If we want to fix the vaccination problem, we have to fix the doctors and get them to stop doing stupid things like prescribing antidepressants for autoimmune diseases. [*]
The science of vaccines is solid. As with anything, it's not entirely risk-free, but the risks are worth the benefits for protection against some serious diseases. It's also irresponsible to put other people at risk. IF (huge IF) there is any correlation with autism, that correlation is miniscule compared to the effects of the other shit we put in our bodies (horrible American diet, pollution, etc.). But people are much more willing to skip a vaccination appointment than not eat that Big Mac.
Incidentally, I heard recently something interesting about flu shots. If those who decide which viruses are being innoculated against predict them correctly, then flu shots work great. If, on the other hand, their predictions are too far off the mark, the flu shot may actually make you MORE vulnerable to viruses that they missed. Of course, you should verify this claim before deciding not to get a flu shot. This isn't a matter of effectiveness of vaccines but rather an issue of getting the right ones.
[*] In medical school doctors are expliclty taught that if someone comes in with a constellation of symptoms, especially if they have them written down, then that person is a hypochondriac. The thing is, auto-immune diseases are not exactly a 1-in-a-million phenomenon. Hashimoto's and Lupus are quite well understood. They come with constellations of symptoms, and they also come with brain fog, which basically forces people to write down their symptoms. My wife had to perform her own differential diagnosis based on the symptoms to determine (abductively) that Hashimoto's is the clear best explanation, but nevertheless, she had to fight with one of the few endocrinologists in the area just to get tested. Of course she tested positive, but even in the face of the evidence, this doctor still doesn't want to engage in any kind of treatment plan. Why? Because endocrinologists make all their money from pushing drugs on diabetics and have no interest in anything else.
