Bill Welsh Presents Mycoplasma Vaccine/Autism Hypothesis to Scottish Parliament

AoA today re-publishes Bill Welsh’s hypothesis first presented here two years ago, which on Tuesday he spoke about before the Scottish Parliament Petitions Committee  (from 1.23.57) raising several important issues concerning the rise of autism, MMR and the possible contamination of vaccine products. A formal publication Bill’s hypothesis can be read here.

Regressive Autism---A New Hypothesis to End an Enigma?

By Bill Welsh.

It is difficult to imagine a worse scenario than the one experienced by the many parents I have met.

To witness a perfect child gradually lose all his or her skills, regress, and develop distressing behavioural difficulties, often including self injury, should never be visited on any family, but the sad reality is it has been occurring increasingly for over twenty or more years. And as if observing the deterioration of the child is not enough- even worse eventually follows, sometimes years later—an official diagnosis of autism (ASD)! Parents soon discover that ‘lifelong’, ‘incurable’ and ‘genetic’ are the three words most associated with the condition. ‘Regressive autism’ is a diagnosis wrapped in bleak negativity.

The latest figures for the UK inform us that over 100,000 schoolchildren have an autism diagnosis. Medical officialdom is quick to re-assure society that there are valid reasons for this significant increase in ASD, including for example ‘better recognition’ and ‘widening diagnostic criteria’.

They are mistaken.

Over 70 years ago autism was identified as a new condition, and was regarded as ‘rare’, that is until about 1990 when its diagnosis began to increase markedly. It is now common. No one in medical science has offered a plausible (one that has survived close scrutiny) explanation for the mystery known as the ‘autism enigma’. This is surprising as there are plenty of clues:

Most, but not all, parents have no hesitation in identifying a vaccination event as the forerunner to their child’s gradual withdrawal. With over 1,500 parents taking legal action, in the usually non-litigious UK, during the MMR vaccine episode one would have thought the role of vaccination would have received very close scientific examination. Inexplicably this did not happen. Official focus remained on the need to maintain public confidence in MMR in order to prevent communicable diseases rather than on a thorough examination of parental testimony. Vaccination as a precursor to a child’s descent into regressive autism became a neglected vital clue.

Another disregarded clue was the consistent reporting by parents of auditory processing disorders in their child. Much of what is seen and described as autistic symptoms (sound sensitivity, communication problems, language development etc) have a clear auditory component while it is highly likely that other symptoms (behavioural difficulties, social functioning etc) might have too. Auditory processing disorders are common in these children. Is this another neglected clue?

A scientific team in the USA carried out a large and important study of twins and concluded that 65% of autism is caused by an environmental factor, leaving only 35% of autism as genetic in origin. This game-changing news, contradicting a long held belief structure, was seemingly ignored!

A, later retracted, gastro-intestinal study of 12 autistic children in the UK apparently identified “a novel form of bowel disease”. The retraction of the study did not dispel the fact that many autistic children experience bowel problems.

In a landmark decision in the USA a child (Hannah Poling) was granted compensation for having developed ASD following multiple vaccinations including MMR. The court’s decision was complicated by the discovery that Hannah had a mitochondrial disorder which we were told may have contributed to her withdrawal into autism. (It has since been established that many autistic children have mitochondrial disorder). Was this another overlooked lead?

Unrelated to the mitochondria connection another team of scientists in the USA identified ‘decreased tryptophan metabolism’ in autistic patients. Another clue?

The clues pile up: an environmental factor as the likely cause; it may be associated (not exclusively) with vaccines; it has a partiality for the auditory tract and could also be associated with bowel disease. And amongst all that- mitochondrial disorder is somehow implicated and also tryptophan depletion!

Where to start?

Interestingly, asearch of the literature on veterinary vaccines reveals the serious concern that pathogenic mycoplasmas, specifically Mycoplasma Fermentans, have generated over many years which may highlight poor ‘quality control’ and a lack of sufficient care in the manufacturing process.

Laboratory scientists will not hesitate in confirming that Mycoplasma contamination of cell lines is one of the major problems in cell culture technology. This mainly occurs through use of animal cell-based approaches in the making of vaccines (e.g. Measles). Antibiotics are added to the growth medium which tends to stop the more ‘common’ types of bacteria from replicating (such as streptococcus or staphylococcus species) but are less successful with mycoplasmas as this genus of bacteria lack a cell wall. Without a cell wall they are unaffected by common antibiotics such as penicillins that target cell wall synthesis.

Mycoplasmas are in fact a covert contamination of vaccines, and extremely difficult to detect and eliminate.

How do mycoplasmas interact in the human body?

Mycoplasmas are able to hide inside the cells of the host (patient) or to attach to the outside of host cells. Whether they live inside or outside the host cell, they depend on host cells for nutrients such as cholesterol, amino acids, etc. They compete with the host cells for these nutrients which can interfere with host cell function without killing the host cell.

Let us re-visit the clues:

Mycoplasma fermentans is a known vaccine contaminant.

Limited veterinary research suggests that mycoplasmas may favour the auditory tract. This would not be surprising as mycoplasmas have an affinity for the cilia and stereocilia. Cilia are slender, microscopic, hair like structures or organelles that extend from the surface of nearly all mammalian cells. The stereocilia are the sensory hair cells of the cochlea in the inner ear, they are vital to the function of the auditory system.

Mycoplasmas have been the subject of much research in the area of bowel disease, Crohns Disease and also Reflux, a frequently reported problem for regressive autistic children.

Interestingly, mycoplasmas affect the function of mitochondria. In fact mycoplasma infection competes with the mitochondria and, as well, infects the cells containing mitochondria and the mitochondria themselves.

Mitochondrial malfunction can be a symptom of mycoplasma infection.

Tryptophan is one of the amino acids that mycoplasmas scavenge from their host’s tissues.


Even a cursory examination of the history of mycoplasmas reveals that they are able to hide inside the cells of the host (patient) or to attach to the outside of host cells.

Mycoplasmas are an incredibly malicious and virulent species of bacteria and are not only extremely clever, they are very difficult to trace. Also it is most likely that should mycoplasma enter the human body’s bloodstream they will over time invade virtually any cell they choose, causing a “gradual deterioration” in the patient. And no doubt, like other pathogens, they will target cells (favoured locations) in the host, e.g. the auditory tract, the gut, and the CNS.

It is unlikely that mycoplasma infection will be readily identified using a standard blood test. The nature of the pathogen is that it becomes intracellular; therefore a more sophisticated approach to testing is necessary. (The MELISA test has been proposed by some.)

The delay between the child’s early regression and the identification of mycoplasma fermentans as the cause may be a significant factor in the progression of this opportunistic bacterial infection leading to medical co-morbidities.

Parents will be interested to learn that a treatment expressly for mycoplasma infection is currently in phase 3 of clinical development. Medical herbal remedies already exist.

This abridged hypothesis outlines the putative involvement of the pathogen mycoplasma fermentans as a potential aetiological agent and that vaccination is one likely conduit for this covert pathogen and a cause of the symptoms commonly seen in regressive autistic children. It is an abbreviated version of the scientific paper: Mycoplasma Fermentans and deciliation as a precursor to Regressive Autism.(copyright Bill Welsh).

Reading Is Fundamental
Most, but not all, parents have no hesitation in identifying a vaccination event as the forerunner to their child’s gradual withdrawal. With over 1,500 parents taking legal action, in the usually non-litigious UK, during the MMR vaccine episode one would have thought the role of vaccination would have received very close scientific examination.

With a birth cohort well over 600,000 in England and Wales, I fail to see any way in which this is not another unexamined use of "most."


Good article. My son was born a perfect baby boy, earning the nickname of Mr. Personality...until falling into this thing we call 'autism' within one week of his vaccines, including MMR... At 18 months... Suddenly becoming 'an empty shell'. He lost what little speech he had left at age 3 after a tetanus shot. This is merely the tip of the iceberg. My son will be 25 in March. As I write this at 3:15 AM, he is still awake, running amock through the house, just ran out of the room with all of his shoes and the shoe rack that was attached to the door, there is a pile of jackets, coats, sweatshirts in a pile on the floor , he routinely empties the content of the fridge in the middle of the night, he cut the pockets off all his shirts last Saturday... List goes on...He has no speech or effective means of communication, no academic skills, limited personal care or social skills. I must shower him, shave him, brush his teeth...He must be supervised 24/7 for his own safety, must be locked in the house with double keyed deadbolt locks...etc. My oldest brother has undiagnosed Aspergers...very apparent to me, now that I have raised a son with autism... My brother can function in society, drives a car, holds a job, is married. My son will likely never experience these things. According to my mother, My brother developed encephalitis around age 5 and suddenly changed from the child he once was. My belief is that vaccinations had much to do with this. This would have been in the early 60's.

I must have missed this one previously. I find it extremely interesting. We had myco tested a few years back with the conventional blood test from Lab Corps. As they scale it-my grandson's count was 1780 and normal is about 0.9. Working with our medical autism specialist and anti-biotics for well over a year those numbers eventually went down to 200. Looks like it's time to revisit this and retest, perhaps in a better testing method. Thank you for this information.


Well done Bill! I admire your tenacity and determination to keep coming up with this 'hot potato', and hopefully the research you have carried out will give them food for thought. You raised some very valid points. I think this all sounds very positive in that they are prepared to approach the Chief Scientific Officer - and also the Department of Health in the European parliament to see what is happening in Europe. I think we already know the answer to that one! The suggestion that a second expert group should have a look at a possible connection between MMR and autism could be a big step forward. It will be interesting to hear what the responses are from the various bodies.
The cynic in me has often thought that it will be the spiralling cost of autism that finally pushes them into actually taking action. They should be doing it for the children and families, but that doesn't seem to be how the world works at present. Maybe the fact that you also suggested a treatment and a way of stopping contamination, will urge them on?

There is as much baggage with Mycoplasma fermentans as there is with Thimerosal or any of the other adjuvants. Looking at the literature, this bug has a history. It was used in secret experiments on prisoners in Texas. I don't think anyone is going to study it any time soon.

Stephen Buhner is the go-to guy for herbal protocols, he has an extensive set of books. For mycoplasma, see Healing Lyme Disease Coinfections: Complementary and Holistic Treatments for Bartonella and Mycoplasma.

All of the herbs he recommends are well-researched (just not in the US), and Stephen is extremely knowledgeable about the science behind both the infections and using herbal protocols to treat them.

For good-quality herbs, we like Sage Consulting and Apothecary:

All of the herbal protocols have three components:

(1) Calm down the immune system and stop any cytokine storm caused by the infection. This stops the immediate damage, much of which is from over-activation of the immune system, and it also prevents the infection from using your immune system against you as it intends. (Many/most of these chronic infections are masters of immune-systems judo.)

(2) Balance the immune system via adaptogens, so it can respond effectively. Vitamin A is also important, because chronic infections tend to deplete this. (Along with Vit D, K2, magnesium, etc.)

(3) Herbs that specifically target the infection, to reduce the load the immune system has to cope with. But the true healing comes from (1) & (2): when you immune system is working and can see the infection clearly, that's when you will heal and stay healed.


What is the clinical trial?
What medicinal herbal remedies?

Well done Bill. This excellent presentation to the Scottish Government petitions committee, follows the compelling presentation by John Stone and Angus Files, reported earlier in a previous AoA article.

Inevitably, one Committee member brought up the now 18 year old subject of the 'discredited doctor' (Andrew Wakefield). Bill responded well, stating Dr Wakefield had merely made a hypthesis about the causes of autism in children, a hypothesis Dr Wakefield was deliberately prevented from researching in the UK. Meantime autism cases have rocketed in Scotland. A low estimate of what this is costing taxpayers is an annual £3.5BILLION. Bill's paper also puts forward a causation hypothesis. I found Bill's research rivetting.

It's so sad, our politicians are perfectly happy to accept the word of pharma sponsored health professionals, and often conflicted Government officials, desperate to protect their own positions and reputations. The most recent episode was a shameful press statement by Clinical Director of Health Protection Scotland, Dr Syed Ahmed, who blamed Dr Wakefield for a dramatic rise in teenage MUMPS. The majority of cases occurred in fully MMR vaccinated young adults, in colleges and universities. For some time it has been officially admitted the mumps MMR component wears off; even pro vaccine spokesman Paul Offit states this happens 'after around 10 years'. Adult mumps is far more serious than child mumps and can cause sterility.

It seems a teenage THIRD MMR jab is to be introduced to solve this problem. I hope the 'teenagers' tell them where to stick their needles!!
