Terrain Theory vs Germ Theory

Very recently I was introduced to terrain theory, which seeks to explain disease differently from germ theory. I would like this thread to cover what this idea is. How it is sometimes related to HIV denialism or Covid denialism is on topic, but no one disease should take over this thread. My present but evolving position is that terrain theory becomes a conspiracy theory when, for example, a subject such as prescription drugs comes up. I am a firm proponent of germ theory. For example, I think that germ theory is flexible enough to account for the observation that not everyone who is exposed to a pathogen gets sick.

Here is one quote from someone with a nutritional perspective and who apparently believes a version of terrain theory, "“Germ theory” suggests that germs are what we need to worry about and we need to keep finding ways to kill them off. Whereas “terrain theory” argues that if the body is well and balanced, then germs that are a natural part of life and the environment will be dealt with by the body without causing sickness."

I found an essay at The Medium from Tudor Alexander, someone who seems to be expounding a nuanced version of terrain theory. He wrote, "Today, many years later, the conclusions of Terrain Theory have been avoided or outright suppressed in the education of both the people and doctors because, frankly, they aren’t highly profitable. If Terrain Theory has the priority in healthcare, then your focus is not the endless war against germs and outside forces but rather the strengthening of the body so that it can do what it was designed to do: keep you healthy...Chemicals do not strengthen anything and often lead to more problems..."

Mr. Alexander goes on to write, "By shunning, censoring and removing alternative viewpoints from education and healthcare we have completely ignored the Terrain. As a result, the average US citizen is sicker than their counterpart in any other major industrialized nation. In the 1960’s about 1–2% of children had chronic diseases and today, a few decades later, that number has risen to about 40–50%.(1)... Germ Theory has helped us create specific, targeted solutions to highly infectious pathogens or serious diseases. There are situations where supporting the Terrain alone will not solve the problem."

I found an essay at The Conversation and one at Popular Science. Modern terrain theory derives from Antoine Bechamp, but it is my understanding that the ideas have changed over time. From The Conversation, "Instead he [Bechamp] thought illness essentially depended on “tiny molecular granulations” called microzymas, which only become pathogenic when a change in environmental balance or function made them so. It was from this change in the bodily “terrain”, and not from germ invasion, that illness arose." From Popular Science, "In other words, he [Bechamp] believed that disease causes pathogens, and not the reverse."
 
One problem is that there were several diseases that were commonly caught by children. These kept them away from school and even killed off a few of them. Now vaccines have prevented most of these diseases.

The main problem is that the immune system has less to do and may cause trouble. So may we need to start giving it something to do.
 
False Dichotomy.

When the symbiosis we have with microorganisms in our guts and on our skin isn't enough to prevent the spreading to a pathogenic vector, only then will we try to kill the pathogen with therapies, or, more often, assist the body to do so itself.
Current Germ Theory already includes everything positive Terrain Theory might have to offer - if we had antibiotics that only target the pathogen, we would use those: we don't nuke our microbiome just for the fun of it.

That is precisely what vaccines do: give your immune system a workout but in a safe space.

That is one solution. Every so often give yourself a vaccine. It does not matter if you do not need the vaccine. I wonder what impact that will have on people who have auto immune disorders? Because those are the people who would need to do this. However my Googling does not reveal any research on this. There are even reports that vaccines could, in isolated cases, cause an auto immune disorder. Ref: https://pubmed.ncbi.nlm.nih.gov/26728772/

That's not what I said. Don't put words in my mouth, please.

And this really pisses off those who practice medicine that is narrative-based rather than evidence-based.

The old 'childhood diseases' like measles were ideal for quacks. Being viral, there wasn't much actual medicine could do for them. In most cases the child would have got better anyway, and a quack could use the post hoc fallacy to take the credit.

The main problem is that the immune system has less to do and may cause trouble. So may we need to start giving it something to do.

the vaccines give the immune system the same things to do as the diseases they prevent. That's how they work.

Tudor Alexander (The Medium) wrote, "If you believe in Germ Theory as the absolute truth, then that means all disease and dysfunction is caused by some sort of pathogen that you need to defend against." This sentence ignore genetic diseases. He wrote, "By creating pharmaceutical drugs and medicines, a whole new avenue of business was born — of which, Rockefeller stood to gain billions." Rockefeller made his money through oil, and the connection between that and pharmaceuticals dubious. "Chemicals do not strengthen anything and often lead to more problems. Supporting the immune system, supporting proper functioning of the various processes and systems with a complete nutrition program and creating a terrain that is as inhospitable for disease as possible are the goals of any discipline based in Terrain Theory." Mr. Alexander is enamored of vitamins, but vitamins are also chemicals.
 
This is just thinking out loud. If a person believes in terrain theory, what do they believe about animals who get sick? What do they believe about plants that are attacked by fungal diseases, for example? EDT: Or what about bacteria that get infected by viruses? Enquiring minds want to know.

The other problem is that we know germ theory is correct, we know that treating germs treats disease, and we've literally seen and examined the germs and understand how they work.
 
That would be Tudor Alexander the god-botherer and ballroom dancer?
Personally prefer to get my medical information from people who studied, well, medical sciences.
 
At Ars Technica Beth Mole discussed RFK Jr. book on Dr. Fauci. She wrote, "In the chapter, Kennedy promotes the "miasma theory" but gets the definition completely wrong. Instead of actual miasma theory, he describes something more like terrain theory. He writes: "'Miasma theory' emphasizes preventing disease by fortifying the immune system through nutrition and by reducing exposures to environmental toxins and stresses." She continued, "To this day, Kennedy writes, a '$1 trillion pharmaceutical industry pushing patented pills, powders, pricks, potions, and poisons...'" I have been pondering one way to rebut the vilification of the pharmaceutical industry that must be part of terrain theory. I find it convincing that we know how penicillin, for example, works in atomic detail. The same is true of Paxlovid.

In my experience it's the 'alternative' medicine industry that pushes pricks.
 
Here's my problem with Big Snake-Oil; those who promote alternative meds are always 100% certain in the outcomes. Real medicine is rarely 100% certain. The alternative gang hasn't changed their tune in the 45 years with each sub-group pushing their miracle cures with the same lines of BS.

Meanwhile, medical science has evolved in those 45 years. In the 80s I had a rescue inhaler for my asthma attacks, and today I still have a rescue inhaler, but now I have another inhaler that prevents asthma attacks completely. Type-2 diabetics have a bunch of options for medications that aren't insulin. Last week I had chest x-rays and I didn't have to take my shirt off, and I was in and out in 4 minutes. And most of us old guys notice our younger doctors are all advising healthier diets, and exercise (which I guess they always did). Every aspect of medical science has evolved, and continues to evolve as new data emerges.
 
I personally long for the day my doctor advises me to lose some weight, exercise more, and cut back on the alcohol. Damn you Big Pharma!! 😡

There still are.

They still do. Vaccines prevent most of the worst diseases, but it's called the common cold for a reason, and children as well as adults still get the flu and C19 because the vaccines against them don't give you sterilizing immunity, the immunity that it does give you wanes, and some people don¨t get the available vaccines.
The main problem is that the immune system has less to do and may cause trouble. So may we need to start giving it something to do.
You are promoting the idea of immunity debt, which became popular among fans of herd immunity by infection when the COVID-19 pandemic started. It is nonsense!
Debunking the myth of immunity debt (HealthyDebate, Jan 9, 2023)
‘Immunity debt’ is a misguided and dangerous concept (Financial Times, Nov 23, 2022)
People are exposed to pathogens all the time. We don't live in a bubble. The immune system doesn't need to be given something to do. It is doing it all the time.

In the case of C19, the idea of immunity debt is particularly absurd because, much like the measles, C19 weakens the immune system.
Did you ever hear about immune amnesia? It doesn't mean that the immune system forgets how to fight off diseases because it hasn't "been given something to do."
Measles Infection Can Cause Immune Amnesia (UCLA Health, April 4, 2025)
This is a phenomenon in which portions of the immune system’s memory are wiped clean. It occurs because the measles virus can invade not only the cells of the respiratory system, but also the cells of the immune system. This includes the memory B cells, which are specialized white blood cells whose job is to recognize pathogens that the body has encountered and fought off before. When alerted by the memory B cells that they have come across a known pathogen, the immune system can swiftly mobilize the specific antibodies it needs to target and overcome the invader.
Without that early warning system in place, the immune system is perpetually flying blind. This leaves the person susceptible to contracting secondary infections from other pathogens, including those that they have successfully fought off before. Researchers have found that, after recovering from the measles, the immune system is suppressed for at least several months, and for up to two years.

SARS-CoV-2 infection weakens immune-cell response to vaccination (NIH, Mar 20, 2023) Read it before Jay Bhattacharya deletes it!
Study: COVID can trigger changes to the immune system that may underlie persistent symptoms (CIDRAP, July 18, 2024)
Cytokines and growth factors in the blood were characteristic of remnants of acute inflammation at 10 weeks post-infection, and a comparison with the patient samples collected 10 months after showed a significant reduction in immune cells, a drop in SARS-CoV-2 antibodies, and a change in growth-factor patterns.
Rather than activation and expansion of certain effector memory cells, transitional B cells, and immature B cells called plasmablasts, the researchers found a significant reduction of adaptive immune cells, including T cells and B cells, at 10 months.
COVID-19 survivors also had significantly upregulated serum interleukin-4 (IL-4) levels and moderately upregulated IL-5 concentrations. Interferon-gamma levels, which were similar to those in the literature for controls and COVID-19 survivors at 10 weeks, had significantly declined by 10 months.
S- and RBD-specific immunoglobulin G antibodies were undetectable in nearly 18% and in more than 80% of the COVID-19 cohort, respectively, by 10 weeks and 10 months. "Moreover, more than 90% of patients lacked neutralizing antibody activity at 10 [months], implying that a large proportion of study subjects after their first infection lost protection from reinfection," the researchers wrote.

Infections can not only weaken your immune system, they can also trigger it into attacking things that you don't want it to attack, i.e. autoimmunity!
New Research Suggests Increased Risk of Some Autoimmune Disorders After COVID-19 (JAMA, Dec 13, 2024)
New research suggests SARS-CoV-2 infection may increase the long-term risk of autoimmune or autoinflammatory connective tissue disorders.
People who contracted COVID-19 were more likely to develop conditions such as alopecia, vitiligo, Crohn disease, ulcerative colitis, rheumatoid arthritis, and systemic lupus erythematosus, among others. These disorders were more prevalent in unvaccinated individuals, those with severe COVID-19, and people infected with the Delta variant, the study found.
A friend of mine got Guillain-Barré syndrome more than six months ago. She still hasn't recovered.
Risk of Guillain-Barre syndrome 6 times higher after COVID infection, study suggests (CIDRAP, Oct 18, 2023)
A new study from Israel ties COVID-19 infection to an increased risk of a diagnosis of Guillain-Barre syndrome (GBS) within 6 weeks, while mRNA vaccination was linked to a decreased risk of the rare but serious autoimmune disease.

It is no coincidence that one of the favourite slogans of Big Supplements is that their products and therapies "strengthen the immune system."
They don't! And sometimes, as in the case of vitamin A, they make everything worse!
Some measles patients in West Texas show signs of vitamin A toxicity, doctors say, raising concerns about misinformation (CNN, Mar 26, 2025)

We don't need to start giving the immune system something to do.
We need to start giving it a rest!

Get vaccinated, mask up, ventilate and filtrate the air in indoor public places.

Yeah, if you think about it, vaccines are the one thing that really do "boost your immune system". Although, "boost" might not be the best word. More like, they give it advanced intel so that it can recognize a particular pathogen before it encounters it in the wild, and can stockpile the weapons it needs to fight that pathogen ahead of time, instead of making them from scratch after the pathogen gets a head start.

Get someone to give you a vaccine when you actually need one.
Don't get vaccinated for fun or because you imagine that your immune system needs training! It's a false analogy.

Your Immune System is Not a Muscle (Rachel Thomas, Aug 13, 2024)

Since the 1990s, a small group of researchers have been promoting the idea of a Non-specific effect of vaccines (Wikipedia).
A disproportionate number of those doctors are Danes, unfortunately, e.g. Peter Aaby and his wife Christine Stabell Benn (on X). Their hypothesis was that "two live attenuated vaccines, BCG vaccine and measles vaccine" (Wiki) had other positive effects than just fighting off the infections that they were meant to protect against, a kind of positive side effect.

However, Aaby and Benn now have their backs against the wall because they appear to have been cherry picking their data to make it seem as if the data supported their conclusions.
Lukket grundforskning (Weekendavisen.dk, April 3, 2025)
En udødelig hypotese (Weekendavisen.dk, Mar 5, 2025)
And what is worse, in order to support their own hypothesis they campaigned against the diphtheria, tetanus and pertussis vaccine (DTaP)! Yes, they were active anti-vaxxers!
RFK Jr. refers to Peter Aaby and Christine Stabell Benn when he claims that the DTaP vaccines are dangerous!
Friske vaccinetal (Weekendavisen.dk, Mar 14, 2025)
Et dårligt immunforsvar (Weekendavisen.dk, Feb 20, 2025)

And their anti-vaxxer sentiments don't stop there. Christine Stabell Benn (along with Danish-American Tracy Beth Høeg) even became an adviser to Ron DeSantis and Ladapo.
Den rigtige vaccine (Weekendavisen.dk, Mar 23, 2025)

By the way, the Wikipedia article about the alleged non-specific effects of vaccines needs to be revised!


ETA: As for, "There are even reports that vaccines could, in isolated cases, cause an auto immune disorder. Ref: https://pubmed.ncbi.nlm.nih.gov/26728772/"

My favourite example is Pasteur's first rabies vaccine:
Paul A. Offit: Vaccinated (HarperCollins)
As his vaccine was injected into more and more people, Pasteur found something that he hadn't anticipated: some people - as many as one of every two hundred who used it - became parolees and died. At first, Pasteur thought that people were dying of rabies. But they were dying of a reaction to he's vaccine.
(...)
Some people inoculated with myelin basic protein occasionally have an immune response against their own nervous systems: autoimmunity.
That was still pretty good odds for a vaccine against a disease that is 100% fatal when you consider that it is one of the few vaccines that works after you have been infected. Used for a mass vaccination campaign, it would obviously be unacceptable.
And fortunately, odds got considerably better once Pasteur stopped using the dried spinal cords of infected rabbits to make his vaccine.

I can recommend Offits book, it's great! And an easy read.

Imagine what North America would look like if Native Americans had a smallpox vaccine. What would Europe look like had there been a vaccine for the plague?

Space heaters, candles, and balloons kill more people every year than vaccines, but no one is suggesting we get rid of them.
 
By the way, the Wikipedia article about the alleged non-specific effects of vaccines needs to be revised!

I should have read all the way to the bottom of the Wikipedia article about the alleged non-specific effect of vaccines where it says:
Non-specific effect of vaccines: Controversy
In 2013, WHO established a working group tasked with reviewing the evidence for the non-specific effects of BCG, measles and DTP vaccines. Two independent reviews were conducted, an immunological review and an epidemiological review. The results were presented at the April 2014 meeting of WHO's Strategic Group of Experts on Immunization (SAGE). WHO/SAGE "concluded that the findings from the immunological systematic review neither exclude nor confirm the possibility of beneficial or deleterious non-specific immunological effects of the vaccines under study on all-cause mortality. The published literature does not provide confidence in the quality, quantity, or kinetics of impact of any non-specific immunological effects in young children after vaccination. [...] SAGE considered that the non-specific effects on all-cause mortality warrant further research. [...] SAGE considered that additional observational studies with substantial risk of bias would be unlikely to contribute to policy decision making and therefore should not be encouraged."
 
Another one from Jonathan Howard:
Dr. Vinay Prasad is Now the Medical Establishment. It’s His Job to Run RCTs, and It’s Our Job to Call Him a Lying Piece of $#!& if He Fails. (Science-Based Medicine, May 9, 2025)
From claiming COVID vaccines were perfect and would end the pandemic to treating rare, temporary vaccine side-effects, even abnormal lab values, as a fate worse than death, Dr. Vinay Prasad spread copious COVID misinformation. It’s taken volumes to begin to categorize his attempts to repeatedly infect unvaccinated children with SARS-CoV-2.
As SBM readers know, one of the chief ways Dr. Prasad spread doubt and mistrust was via methodolatry. Except for vaccine side-effects, Dr. Prasad claimed that only randomized-control trials (RCTs) could inform medical decisions and that unwanted mitigation measures were useless unless they proved themselves via an RCT for every variant and demographic subgroup.

Some good news, I hope:
Scoop: "Randomized controlled trials are not always necessary," new FDA vaccine chief Dr. Vinay Prasad says to staff. (Inside Medicine on Substack, May 8, 2005)
Introductory comments yesterday reflected a return to nuance from a figure who had become contentious in recent years.

Yes, this. If you are otherwise unhealthy, it makes sense that exposure to additional diseases is more dangerous. That doesn't mean that the other diseases aren't otherwise dangerous though.

You could reasonably argue that both AIDS and the 1917 flu prove terrain theory and the germ theory. Infection by either resulted in lots of death from things people would otherwise be able to resist. Does not prove in any way that protecting someone from AIDS or the Flu is a bad thing.

Confused by this. From listening to that podcast, I understood that RFK was an opponent of the Rotovirus vaccine not a proponent?

No, you couldn't reasonably argue that, and that is not what they claim. People like Aaby and Benn (see post 24) actually claim that only "live attenuated vaccines" have the alleged non-specific effects, and they have been trying to prove that other vaccines are harmful and thus are "a bad thing."
The measles vaccine protects people from the immune amnesia (see post 22) caused by the measles because it protects people from getting the measles specifically, so the effect is by no means unspecific. And the fans of a non-specific vaccine effect claim that it is due to something beyond protecting people from the disease that it immunizes against.

And as mentioned above (see also post 28), this idea appears to be based on science fraud.
 
Funny how there are few vaccines for STDs considering the potential market for them. Flies in the face of the anti-Big Pharma/anti-science crowd. STDs also illustrate how germ theory and terrain theory are linked in that you can't get them by walking down the street. And I don't see too many people complain about Big Pharma when it comes to treating STDs.
 
There are some vaccines against STDs, and attempts to develop more are under way:
Vaccines That Can Prevent STIs (ASHA Sexual Health)

News: Studies indicate meningococcal vaccines could offer protection against gonorrhea (CIDRAP, May 8, 2025)
(But the protection is far from 100%.)

Antibiotics used to be very effective treatments for both gonorrhea and syphilis, which may have made it less urgent to develop vaccines against them. And there are other very effective, non-pharmaceutical, ways to avoid getting the two 'classical' STDs in the first place.

You seem to forget about the anti-HPV-vaccine campaign:
Debunking Myths about the Human-Papilloma Virus (HPV) Vaccine (Pan-American Health Organization)
That one was big in Denmark!
Denmark campaign rebuilds confidence in HPV vaccination (WHO, Feb 27, 2018)
 
The rise of a new form of germ theory denial (Your Local Epidemiologist on Substack, May 8, 2025)
Germ theory does not say all germs are bad, nor does it say germs are responsible for every disease known to humans, nor does it say that any exposure to a germ is a guarantee of illness. It says that certain germs can cause infections that make people sick. And when that happens, the germ really is to blame.

A new subtle form of germ theory denial
But this idea is starting to be rejected and replaced with a new, inaccurate view of why infections happen and what we should do about them.
This new version of germ theory denial still acknowledges that germs are real, but says they’re not all that much of a threat for a healthy individual, and not the real problem causing disease. Instead, when someone catches an infection, the person’s immune system and lifestyle are blamed—an unhealthy diet, lack of exercise, exposure to “environmental toxins,” or underlying conditions are allegedly the “true” cause of disease because they damaged the immune system.
Said another way, it’s the belief that infections don’t pose a risk to healthy people who have optimized their immune system. And if you want to prevent infections, vaccines aren’t the solution, becoming healthier through nutrition, exercise, and dietary supplements are.
This version of germ theory denialism has become quite common. It’s what drove the comorbidity fallacy during the pandemic—the belief that COVID wasn’t really what was killing people, that underlying health conditions were actually to blame. It also drove the rumor that if you just eat right and exercise enough, there’s no reason to get vaccinated, because your immune system will be sufficiently “boosted.” More recently, it can be seen in the rumor that vaccines didn’t really cause the decline in vaccine-preventable illnesses like measles and polio during the 20th century, rather, better nutrition and sanitation were the true drivers.

The article continues with "RFK Jr.'s view on germs."
 
My immediate reaction to the OP was that taking care of my general health is what I normally do to stay fit and healthy, and that includes being less susceptible to infection because of general robustness. Had never heard of the theory until now. I do get sick far less often these last decades, but that is mainly because I've had a chance to build up immunities and resistances over a lifetime. Vaccines help, too.

"Terrain theory" seems to be a fancy term for the age-old obvious "apple a day" type advice. I'd need to hear something game-changing, some more than coincidental relation to normal health measures in order to lend some credence.

As far as aging is concerned, maintaining a healthy level of social interaction and a light exercise regime seem to be the winning longevity combo. Meanwhile, I avoid germs and wash my hands before eating and whenever I've been out. Done!

Wife has cooties, though, and can use them to control me at will, so there's that. :eusa_doh:

I respectfully disagree with this portion of your comment. IMHO terrain theory puts too much of the responsibility on the individual, in the sense that it implies that if you get sick, it is your fault. Some people are born with subpar immune systems (the genetic condition SCID comes to mind), and others become immunocompromised from lymphoma or other diseases. It also ignores the fact that new pathogens appear and old ones evolve. However, I would agree that terrain theory can appear reasonable on the surface. Nor do I disagree with the proposition that good nutrition and exercise are important components of good health.

Ya, terrain theory goes a bit beyond an apple a day. Most proponents seem to think if you just live a healthy life you'll never get sick and then go on to say that medicine is therefore bad. A leap of logic I can't quite follow. So, if I was healthy I wouldn't have gotten sick so I shouldn't take the medicine that will cure me? The anti-vax thing is.... well I have no idea how that follows from terrain theory. Which seems to be why folks like RFK go beyond just terrain theory and start claiming vaccines are actually bad for you.

(ETA: I mean, if terrain theory were true, how would a vaccine even cause harm?)

I'm just thinking out load but, I just don't get it. If terrain theory was true, vaccines could still work. Ok, so a flu can't kill me if I'm healthy to begin with and also vaccines could improve my terrain and helping me fight off the virus just like healthiness can.

Then there's the thing where they seem to blame modernity for our unhealthy terrain, what were all those folks dying of before modernity?

There is a soft version of terrain theory that is basically true, which is an apple a day keeps the doctor away. That is if you are otherwise healthy, you are generally better able to fight of the germs that cause disease. RFK and his fellow travelers never stop there though. Its almost as though they first decide that modern medicine is bad and then use terrain theory as justification.
