I'm sure there are medical journals that have published studies on this. However, I'm taking this question and answering it in a different context that is truer than any 'Germ Theory' study could answer. I regret the following long answer. I'll forewarn you in advance. If you want to read the last paragraph, it will provide insight to Ivermectin.

If one was to know that 'there are no specific diseases, but rather are specific disease conditions', one would have a much better insight to disease formation. It really boils down to these two ideologies. If we imagine a sick gold fish. Germ theory would have us vaxxinate the gold fish. Terrain theory would have us clean the contaminated water.

Before you close the 'book' on this, please try to follow me and I promise I will answer your question. Let's first get down to honest facts manifested through observation. Disease is really caused by a consistent violation of the Laws of Nature. There is no question that the Laws of Nature are constantly being violated when we were called to abide by them in Genesis. In fact, I have found that people really don't even know what the Laws of Nature are. It seems no one ever asks -- "What specifically are the Laws of Nature? I've researched this topic for more than 20 years and found even Thomas Aquinas does not answer this. The reason for it appears to be that the answer was so obvious to everyone because it was 'seen by all those' who lived.

“Because the thing known of God is clearly known in them, for God revealed it to them. For the unseen things of Him from the creation of the world are clearly seen, being understood by the things made, both his eternal power and Divine Nature, for them to be without excuse.” - Romans 1:19-20.

Not anymore. I have found the answer was 'so obvious' to the ancient Greeks that nary was it ever spelled out to the rest of us. The Laws of Nature in basic terms are the immutable rules of life itself for 'each' kind after its own kind. Each kind strives to maintain an 'optimal balance' of health until death. The Laws of Nature is broken when 'optimal balance' is not obtained and maintained. For us, this includes many factors that cause disease formation. Poor diet of largely processed, over cooked, and low nutrient dense diet, stress, toxic beliefs and thoughts, emotional suppression, a lack of exercise, fresh air, and sunshine, and an accumulation of environmental poisons are all contributing factors that compromise our immune systems and cause disease formation.

The main cause of disease in the early part of the 20th Century and before was the lack of sanitation, hygiene, and nutrition. Fecal matter from farm animals used for mass transportation and humans contaminated nearly every aspect of daily living, including the drinking water. Today, the infrastructure in the United States for sanitation systems has greatly minimized all the common diseases from fecal matter. Ironically, it wasn't the medical doctors and the vaccine industry that eliminated common disease. The credit actually goes to...... Are you ready? The credit goes rightfully belongs to plumbers, electricians, sandhogs, engineers and city planners. I will go as far to state that a pandemic is extremely improbable to occur in the United States unless the sanitation system infrastructure collapses. Ever wonder why the Los Angeles and San Francisco mayors allowed the homeless to defecate on the city streets? Do you think they were trying to start a pandemic? Fortunately, it didn't work. Citizens acted and cleaned up the mess.

We are left with the over-abundance of chemical toxicity that builds up in the body. This comes from stress and the environment. As a result of these factors, it creates the ideal environment for germs and viruses to feed on and multiply. This toxicity build-up is referred to as 'toxemia'. As late Dr. Herbert Shelton stated-- “Toxemia is the product of fermentation and decomposition, .... These are the things that enervate and enervation lowers functional ability. Toxemia clogs the organism, every cell, tissue, organ, nerve fibre, the blood and lymph stream, until one after another the organs of the body break down.”

The belief that germs and viruses cause disease (Germ Theory), rather than toxemia, is something that the Big Pharma-influenced medical industry makes sure we never question.

Renowned scientist Dr Rudolph Virchow, who is considered the father of modern pathology and who was a vocal critic and opponent of the germ theory, said that, “If I could live my life over again, I would devote it to proving that germs seek their natural habitat: diseased tissue, rather than being the cause of diseased tissue.”

In fact, microscopic organisms such as bacteria, viruses, and fungi comprise more than half of the cells (57%) found in the human body. Another analogy that is helpful in understanding this (terrain theory), is to imagine a deer that fell over in the forest and died of a natural cause, such as old age. The moment that its heart stops, the ‘terrain’ of the deer’s body instantly begins to change. The blood loses oxygen and becomes highly acidic, the organs cease detoxifying causing the blood, lymph, and tissues to become toxic. This change of terrain then causes the trillions of viruses and bacteria that were already present on the deer’s body to change their function. Only minutes and seconds prior, they were in fact helping to maintain the health of the deer, but now they will begin feeding on the deer’s dead tissue in order to help decompose its body back into the earth. This is the function given to them by nature, and if this weren’t the case, then Earth would be littered with dead bodies everywhere.

What we call disease is the body’s attempt to heal and purge itself of the numerous poisons that have accumulated as a result of toxemia, and to heal itself of the damage those poisons have caused. It is also the body’s attempt to force us to rest so that it can restore optimal balance. What the medical establishment claims to be viruses, are manifestations of our own bodies that happen when there’s an insult. They are a reaction to toxins, a defense mechanism.

In realizing this, how does Ivermectin work as a cure for COVID-19? Ivermectin is an effective de-worming and delousing medicine. Thinking in the context that the immune system is already weakened by 'some' toxin or combination thereof, and with acknowledging the CDC has admitted they have not isolated nor purified COVID-19, we must rely on Ivermectin ridding the body of some parasite causing symptoms of the disease. We know that the 'lupus' can be cured by ridding the liver of parasites. This is just another case of calling the symptoms a disease when it's cause is from 'something' totally else.
