Many people aren't aware that the brain has its own immune system and since vaccines trigger an inflammatory response, they are also capable of permanently 'switching on' the brain's immune system so that they constantly pour out pro-inflammatory cytokines. This chronic activation of the brain's immune system can cause brain inflammation and neurological damage and has been likened by some researchers as an allergy of the brain.
Scientists were able to induce brain injury and haemorrhage in rats who were given BCG vaccine by an IV route because of chronic monocyte activation:
We have proposed that an increased interaction between monocyte/macrophages and blood vessel endothelium predisposes subjects to strokes. The effect of chronic monocyte activation on the development of cerebral infarcts was thus studied in rats after provocation of a modified local Swartzman reaction, in brain vasculature.
Two weeks after an IV bolus of bacillus Calmette-Guérin (BCG), we studied spontaneous superoxide production, integrin expression, endothelial adhesion of monocytes and the neurological symptoms, brain histology, and cytokine immunoreactivity after a provocative dose of LPS (30-300 microg/rat i.c.v.).
Monocyte migration into the brain was stimulated by BCG priming. The incidence of paralysis and death in response to LPS was markedly increased in BCG-primed rats. Histological evaluation of the brains of neurologically impaired and moribund animals revealed intravascular thrombosis and pale and hemorrhagic infarcts. Infiltrates of leukocytes expressing immunoreactive IL-1:, IL-6, and TNF-alpha were found around blood vessels, cerebral ventricles, and meninges, and were accompanied by a profound microglial expression of IL1P, endothelial expression of IL-6, and expression of TNF-alpha and TNF-R 1 in glia and neurons of cortex and hippocampus. Treatment (2 x 100 microg/10 ,I, i.c.v.) with recombinant human (rh-)TNF 55kDa receptor completely prevented, and treatment with rh-IL- I receptor antagonist significantly decreased the incidence of paralysis and death in response to BCG + LPS. The improvement of neurological symptoms was accompanied by reduced histological damage and supppression of IL-1P/ expression in the brain tissue.
The data demonstrate that chronic monocyte activation predisposes subjects to thrombosis and hemorrhage via an exaggerated release of proinflammatory cytokines.

Here is a paper where baby rats were brain damaged by injections of toxins after they permanently activated their brain's immune system:
Cytokines are important intercellular messengers involved in neuron-glia interactions and in the microglial-astroglial crosstalk, modulating the glial response to brain injury and the lesion outcome. In this study, excitotoxic lesions were induced by the injection of N-methyl-D-aspartate in postnatal day 9 rats, and the cytokines interleukin-1 beta (IL-1beta), interleukin-6 (IL-6), tumour necrosis factor alpha (TNFalpha) and transforming growth factor beta 1 (TGF-beta1) analysed by ELISA and/or immunohistochemistry. Moreover, cytokine-expressing glial cells were identified by means of double labelling with glial fibrillary acidic protein or tomato lectin binding. Our results show that both neurons and glia were capable of cytokine expression following different patterns in the excitotoxically damaged area vs. the nondegenerating surrounding grey matter (SGM). Excitotoxically damaged neurons showed upregulation of IL-6 and downregulation of TNFalpha and TGF-beta1 before they degenerated. Moreover, in the SGM, an increased expression of neuronal IL-6, TNFalpha and TGF-beta1 was observed. A subpopulation of microglial cells, located in the SGM and showing IL-1beta and TNFalpha expression, were the earliest glial cells producing cytokines, at 2-10 h postinjection. Later on, cytokine-positive glial cells were found within the excitotoxically damaged area and the adjacent white matter: some reactive astrocytes expressed TNFalpha and IL-6, and microglia/macrophages showed mild IL-1beta and TGF-beta1. Finally, the expression of all cytokines was observed in the glial scar. As discussed, this pattern of cytokine production suggests their implication in the evolution of excitotoxic neuronal damage and the associated glial response.

Scientists at John Hopkin's School of Medicine also discovered that autistic children they treated had neuroimmune system activation in their brain tissues and cerebrospinal fluid:
Immunity, neuroglia and neuroinflammation in autism
Here is another paper suggesting that autism is a manifestation of a brain inflammation stimulated by over-activation of the neuroimmune system:
Autism spectrum disorders (ASDs) are characterized by deficits in social communication and language and the presence of repetitive behaviors that affect as many as 1 in 50 US children. Perinatal stress and environmental factors appear to play a significant role in increasing the risk for ASDs. There is no definitive pathogenesis, which therefore significantly hinders the development of a cure.
We aimed to identify publications using basic or clinical data that suggest a possible association between atopic symptoms and ASDs, as well as evidence of how such an association could lead to brain disease, that may explain the pathogenesis of ASD.
PubMed was searched for articles published since 1995 that reported any association between autism and/or ASDs and any one of the following terms: allergy, atopy, brain, corticotropin-releasing hormone, cytokines, eczema, food allergy, food intolerance, gene mutation, inflammation, mast cells, mitochondria, neurotensin, phenotype, stress, subtype, or treatment.
Children with ASD respond disproportionally to stress and also present with food and skin allergies that involve mast cells. Brain mast cells are found primarily in the hypothalamus, which participates in the regulation of behavior and language. Corticotropin-releasing hormone is secreted from the hypothalamus under stress and, together with neurotensin, stimulates brain mast cells that could result in focal brain allergy and neurotoxicity. Neurotensin is significantly increased in serum of children with ASD and stimulates mast cell secretion of mitochondrial adenosine triphosphate and DNA, which is increased in these children; these mitochondrial components are misconstrued as innate pathogens, triggering an autoallergic response in the brain. Gene mutations associated with higher risk of ASD have been linked to reduction of the phosphatase and tensin homolog, which inhibits the mammalian target of rapamycin (mTOR). These same mutations also lead to mast cell activation and proliferation. Corticotropin-releasing hormone, neurotensin, and environmental toxins could further trigger the already activated mTOR, leading to superstimulation of brain mast cells in those areas responsible for ASD symptoms. Preliminary evidence indicates that the flavonoid luteolin is a stronger inhibitor of mTOR than rapamycin and is a potent mast cell blocker.
Activation of brain mast cells by allergic, environmental, immune, neurohormonal, stress, and toxic triggers, especially in those areas associated with behavior and language, lead to focal brain allergies and subsequent focal encephalitis. This possibility is more likely in the subgroup of patients with ASD susceptibility genes that also involve mast cell activation.

Most people including medical professionals assume that the vaccine ingredients cannot go to the child's brain and that the blood/brain barrier will protect the child from any toxins that enter his body, but little is known about the development of the blood/brain barrier or how many years it takes to mature. Certainly, a baby having repeated rounds of multiple vaccinations will not yet have a fully functioning blood/brain barrier.
In addition, a stabilizer routinely added to vaccines - polysorbate 80 (or tween 80) is a known drug delivery system used for delivering drugs directly to the brain. It is capable of crossing the blood/brain barrier and is used in drugs such as anti-seizure medications and anti-depressants where the drugs are needed to affect the brain because it can help the medication go to where it is needed.
This means that in vaccines containing aluminium, thimerosal and other toxic ingredients together with polysorbate 80 can go straight to the brain. Polysorbate 80 is an ideal transportation device. Why vaccine manufacturers and doctors never thought of this is concerning.

The possibility of using polysorbate 80-coated nanoparticles for the delivery of the water insoluble opioid agonist loperamide across the blood-brain barrier was investigated. The analgesic effect after i.v. injection of the preparations was used to indicate drug transport through this barrier.
Loperamide was incorporated into PBCA nanoparticles. Drug-containing nanoparticles were coated with polysorbate 80 and injected intravenously into mice. Analgesia was then measured by the tail-flick test.
Intravenous injection of the particulate formulation resulted in a long and significant analgesic effect. A polysorbate 80 loperamide solution induced a much less pronounced and very short analgesia. Uncoated nanoparticles loaded with loperamide were unable to produce analgesia.
This may explain why measles virus has been found in the brains of autistic children and why an apparently healthy 21 month old baby got measles encephalitis eight months after his MMR, that was found to be vaccine strain.
