This is why it is difficult to rationally discuss the science about this topic, your one experience is not scientific and its based on emotion. I don't deny what you perceived or why you feel the way you do, but it just isn't scientific and you can' argue with scientific evidence, using subjective experiences. Human recall of experiences is routinely unreliable. Emotion gets involved and the mind can make things up. I'm not saying that happened here, I'm saying it could happen.
As has already been expounded, it's not my one emotional experience. There are thousands of parents who noticed behavioral changes in their kids following vaccines. It doesn't get reported because doctors believe the "science" (what they are told by drugs companies) more than they believe the parents who know their own children. The so called thimerosol-free vaccines still contain 1mcg mercury. What happened is that the FDA changed the regulations on what qualifies as mercury free. There's also aluminum and other heavy metals in the vaccines. For example the flu vaccine still contains mercury.
If a child has poor detoxing pathways, then the heavy metals will immediately disrupt their methylation cycle. When the body has compromised detoxing, especially phase II, the first cells to be affected will be nerve cells. After the acute poisoning stage, Mercury then lodges in the organs, with particular affinity for the central nervous system.
We have seen similar problems in children who receive mercury fillings in their baby teeth. Behavioral changes start within days to weeks. Under government health care, all low income families receive mercury fillings instead of the composite resin.
I have seen some autistic children recover a lot of their cognitive function by doing heavy metal chelation with agents such as ALA, DMPS and DMSA. This is discussed a lot in the focus groups. Autism is a disease name with many origins. Heavy metals is just one. My son developed meningitis after his vaccine series. Some immune systems don't just get inhibited by the heavy metals, they actively try to fight it, causing central and peripheral nerve damage... as was the case with my son. The doctors blithely searched for infectious causes meanwhile we kept telling them he just had vaccines. Not only did the neurologist literally laugh in our faces, he did not report the ADR. We had to do that ourselves. This is a common story.
It's all fine and well to walk into a conversation, wave your hand, and call something unscientific or emotional, but there is plenty of anecdotal evidence of connection between vaccine injury and autism, if you'd care to look. Big pharma has turned any researcher who asks honest questions into a pariah. Can't gather the hard science if everyone is too afraid to look. Fortunately, the general public is not bound by such strictures.
It's not even about herd immunity. We already have that for the most part. It's about money, like it always is.
I believe certain genetically susceptible children, like those with a MTHFR, MTR, or MTRR mutation, should either not be given vaccines or they should be given a detox protocol with their vaccination series. However such a protocol can't be developed without the proper acknowledgment and research. The other issue is that 40% of Americans have some variant of MTHFR, which would cause a lot of headaches if we were to custom tailor medicine for all of them. That really is the main problem here... that drugs do not have universal applications. We just think they do because of how we have classified reactions. For example a lot of doctors call a bad reaction an "allergy". An allergy involves the immune system... a histamine reaction. If you're not having a histamine reaction, then it means your body can't metabolize the drug, either due to a mutation in the CYP450 group or a methylation problem like MTHFR.
The fact is, modern pharmacy is a blunt instrument. They take one chemical and expect everyone to handle it. Those who can't just become the "side effect" category. But a side effect is an effect. If you take an entire group of people who are slow metabolizers of CYP3A4, give them caffeine, and they get shaking hands/anxiety, then that is an effect, not a side effect. We can then reliably say that if a slow metabolizer of CYP3A4 takes caffeine, they will have a high likelihood of shaking hands/anxiety.
It's no different than with vaccines. If some subset of the population is prone to CNS effects of vaccines due to genetic mutations, we better figure out what those are and determine eligibility based on that, rather than bury our heads in the sand under the doctrine of herd immunity, which is really just a smoke screen for protecting big pharma's wallet.
