Imagine a time when a person could be suddenly struck with a horribly painful and disfiguring illness, without warning or knowing the cause. And with no cure, they will likely die. Tetanus infections, left unchecked, are gruesome and deadly. The infected person experiences uncontrollable seizures of muscle that make them rigid and distort their face into what looks like a very sick and pained grin. The muscles of the face tense so much the mouth cannot be moved, thus the common name “lockjaw.”
Naturally, humans instinctually want to avoid pain and suffering. Humans are also quite clever and seek solutions that are as easy as possible to use. You may have heard of “one-ill-one-pill” answers to disease — in other words, pharmaceutical drugs. Another approach that the modern medical establishment uses is to create something unnatural and manmade in an attempt to outsmart nature. That something is called vaccines, and the tetanus vaccine is one of the first used on humans.
The tetanus vaccine has been associated with some of the most controversial vaccines ever created, appearing in combination shots with diphtheria and pertussis (like DPT), as well as anti-fertility vaccines created by the World Health Organization (WHO). How did it end up on our vaccine schedules? What do we know about its history, safety, and effectiveness? Let’s start from the beginning…
What is tetanus?
What we call “tetanus” is the illness caused by toxic by-products of bacterial reproduction. This toxin is only produced under very specific circumstances when spores (packets of bacterial DNA) get activated for reproduction.
There’s no lab test for tetanus.[i] Tetanus diagnosis is associated with rigidity, spasms, tightening of the jaw (“lockjaw”), sweating, and soaring fevers that have been documented up to 112o F.
“The diagnosis of tetanus is based on the clinical signs and symptoms only. Laboratory diagnosis is not useful as the C. tetani bacteria usually cannot be recovered from the wound of an individual who has tetanus, and conversely, can be isolated from the skin of an individual who does not have tetanus.”—Immunize.org[ii]
There’s no cure for tetanus, nor any lifelong immunity from either natural infection or a vaccine. A person who recovers from tetanus infection can get tetanus again.[iii]
So how can a vaccine stop tetanus if the body’s immune system does not keep a memory of the infection? Public health professionals argue this is why we need boosters, to keep the antibody circulating unnaturally in our bodies. The consensus among medical professionals is that the unnatural circulation of tetanus antitoxin is a person’s only way to prevent tetanus.
Tetanus is unique on the vaccine schedules because it is the only disease that is considered infectious, but not contagious. In other words, it doesn’t pass from person to person. It is acquired environmentally. Therefore, the tetanus vaccine will never eliminate tetanus as a disease, nor does herd immunity apply.
How do people get tetanus?
“People get tetanus by stepping on a rusty nail” is one of the most oft-repeated myths of disease in our culture. But do rusty nails cause tetanus? What about the plastic end of a drill hitting you in the head in an auto shop? What about a gash from a car accident? What about dental work or simply being born?
Does every deep wound have the potential to harbor a tetanus infection? In short, yes. Does any wound or opening through the skin, regardless of size, have that potential? Yes.
However, are there circumstances that will make a tetanus infection more or less likely? Again, a resounding yes. The risk of getting tetanus changes with geography and behavior, as well as individual circumstances like toxic load and immune system health. Tetanus spores tend to be found in hot, damp climates with soil rich in organic matter.[iv] In some areas, tetanus is rare or unknown, like parts of the Rocky Mountains in the U.S.[v] Infections tend to happen in conditions that are unsanitary or risky. People who use injectable drugs are at high risk for tetanus. Babies born in unsanitary conditions are susceptible to tetanus through unhygienic umbilical cord cutting practices.
Until the second half of the 1800s, the cause of tetanus was unknown. Even among medical practitioners who started to get a picture, there was uncertainty. Tetanus was associated with wounds, but also considered “idiopathic” (of unknown origin) if a wound was not found.
The bacteria known as Clostridium tetani produces toxins when it is in an environment without oxygen. Generally, this is not a problem because it is surrounded by oxygen all the time when it is out in the world. Spores of the bacteria are found in the intestines of animals and in the soil from animal droppings. Dig in your garden and you’ve probably encountered the spores, especially if you live in a rural setting. The bacteria itself does not cause an infection simply by exposure — it is the precise combination of lack of oxygen and the temperature of living creatures that causes the bacteria to start producing a toxin.
The bacterium C. tetani reproduces with spores, which are little packages of DNA ready for germination under the right conditions. People and animals encounter these spores in soil and in the air. The spores are extremely hardy and can withstand a wide range of temperatures, biding time until they are activated for reproduction, which happens under certain conditions and only under those conditions.
It is not the wound itself, nor the thing that caused the wound, that creates the illness. Your entire body could be coated in tetanus spores and you could still be free from tetanus infection. C. tetani bacterium are “obligate anaerobes,” meaning they will only reproduce in an environment without oxygen. The temperature range of 35-37 degrees Celsius (normal human body temperature) is the optimal temperature for reproduction, though it can reproduce to a lesser degree outside of that range. When the spores start reproducing to create new C. tetani, the process produces substances that are poisonous to humans and animals. The most dangerous is called “tetanospasmin,” which is the cause of what we know as tetanus. Tetanospasmin is a neurotoxin, meaning it is a poison to the nervous system.
In a nutshell, when we say “tetanus,” we are referring to an illness caused by the presence of a bacteria that has gone into survival mode, and the bacteria’s survival mechanisms can kill the host.
So where does the rusty nail story come from? The general assumption is that the story came from the recognition that rich, fertile soils are also places where things like automobiles and farm equipment will rust. (Rust happens naturally when certain metals are exposed to oxygen and water over time.) The tetanus-causing bacteria lives in the intestines of animals, so you can easily see the association with farmed or pastured land. It’s found in soil and manure and even dust. Rust doesn’t cause tetanus, but the two can occur in the same environment. When the U.S. was founded, it was largely agrarian, and the rusty nail story was embedded in the consciousness of Americans well before the tetanus vaccine was created in 1924. In fact, a search of newspapers back through the 1800s will turn up articles repeatedly linking tetanus to being scraped or punctured with a rusty nail.
