Can the Jab Cause Autoimmune Disease?
Vaccination and Autoimmunity
Many people are wondering whether vaccinations, like the COVID-19 vaccine, can cause autoimmune conditions to worsen, flare up, or present for the first time. Some people who have recently gotten the vaccine have noticed their symptoms flaring up, or are noticing autoimmune reactions cropping up where there weren’t any before. They’re wondering what’s going on, and whether the vaccine has caused these reactions. This post will explain how vaccines work, and how they can indeed cause autoimmune reactions according to the latest research.
Research shows that vaccinations can cause autoimmune disease. That’s why so many people with chronic autoimmune issues have been noticing their symptoms worsening, and why those with an underlying condition have seen it come to the forefront after getting vaccinated. It’s very prevalent. In fact, you probably know someone in your sphere who’s gotten the vaccination and is now experiencing autoimmune symptoms like brain fog, dulled senses, and neuropathy.
About autoimmune disease
Twenty-three million Americans suffer from autoimmune disease, and of them 78 percent are women. There are more than 80 different autoimmune diseases out there, and it’s the fourth leading cause of disability in women. In fact, there's twice as much money spent on autoimmune diseases than cancer in the United States right now. The problem with autoimmune disease is that each disease has a unique name that doesn’t intuitively link it to the others. Contrasting it to cancer, where you could have breast cancer, bone cancer, prostate cancer, skin cancer, and all have the word “cancer” in the name.

What happens in a body with autoimmunity?
Many new scientific publications have shown a correlation between vaccination and autoimmune disease. Specifically, research shows that the COVID-19 vaccine can cause autoinflammatory dysregulation. This means that your immune system is really flared up. It's confused. Your immune system has to determine every single second: “Is this a friend, or is it a foe?” When you have an autoimmune disease, it sees a lot of things as foe, even though they're not, and it starts to attack it.
An analogy to understand the immune response is this. If you have an autoimmune condition, it’s as though your immune system is drunk. If someone is driving drunk, they may be seeing three sidewalks where there might only be one sidewalk. Your immune system is doing this with your body’s tissues. It might be seeing three brains when there’s obviously only one. The “extra” brains it thinks it sees are going to be attacked, because they’re marked by the immune system as “foe.”
If you have an underlying autoimmune condition, whether it has been diagnosed or not, you’ll have specific antibodies in your system. The research shows that once you have an autoimmune disease, something called molecular mimicry occurs. This simply means that all your body’s tissues look very similar to the immune system. So if you have one autoimmune disease, there's a probability that you have three or four other autoimmune diseases that haven't been diagnosed. This is because your immune system really can't differentiate between your thyroid, your stomach, your brain, and so on.
Testing for autoimmunity
Advanced testing exists, and I use it in my practice, to see if someone has an autoimmune condition. It tests specific tissues in the body – those in your gut, brain, cell membranes, adrenal glands, heart, muscles, connective tissue, collagen, liver, pancreas, and brain – and shows whether the immune system is attacking that specific tissue. Some people may have the autoimmune disease and not have any clinical symptoms. Others may be mild symptoms, like brain fog.
The test looks for the antibodies mentioned earlier. They can be present seven to 15 years before any symptoms come up. That means these antibodies may be there without any reactions until, say, you get the COVID-19 vaccine. Or maybe the trigger is reaching a certain age, or going through a big change like menopause. That can cause the immune system to start attacking the tissues shown in the test to be at risk.
Vaccinations in a body with autoimmunity
With your immune system already compromised, acting “drunk” as mentioned in an earlier example, it’s ready to attack anything that’s foreign in the body. That includes a vaccine entering the system. An insult like that causes a lot of inflammation in your body that's going to accelerate the potential of autoimmune symptoms.

Many new papers exist to show this correlation. However, because this is new research, no study has yet taken someone with a known autoimmune disease, given them the vaccine, and watched what happened. They haven't done any control studies like that. But some of this new research is coming out of Israel, where something like 90 percent of the population has been vaccinated against COVID-19. They’ve found specific links between autoimmune disease and the Pfizer vaccine.
