My Pandemic Story: First Do No Harm

Print Friendly, PDF & Email

“For every drug that benefits a patient, there is a natural substance that can achieve the same effect.” – Dr. Carl Pfeifer

On April 18, 2023, the National Post published an article about two physicians in Ontario who had given up their licenses recently because of their opposition to the Covid mandates, masking, lock- downs, and experimental mRNA jabs called ‘vaccines’. This criticism of the medical status quo was termed “professional misconduct” and considered worthy of a reprimand. I was one of those physicians.

The Post article accused me of recommending Ivermectin to patients for prevention and treatment of Covid (a drug discredited by the medical authorities). But the truth is I never prescribed it because local pharmacies were reluctant to supply it. (Many people were receiving Ivermectin prescriptions from other countries like India through the internet.)

I was in general medical practice for over 44 years. I slowly shifted into Complementary and Integrative medical practice after five years of conventional medicine. I have published 12 books on natural medicine including the Encyclopedia of Natural Medicine and Vitamin D: The Sunshine Vitamin. I resigned my membership in the College of Physicians and Surgeons of Ontario and gave up my practice certification in November 2022.

I have also published dozens of articles in Vitality magazine since its inception and have given yearly presentations on natural medicine at Whole Life Expo until the pandemic forced a stop to all conferences.
Prior to my work with Vitality, I was the Alive Magazine Advisor and wrote articles for them for over 20 years during the 1980s and 90s.

Approximately 15 years ago the College of Physicians and Surgeons (CPSO) began investigating physicians who practice Complementary and Alternative Medicine (CAM), looking closely at their medical records, their prescriptions for natural hormones like desiccated thyroid, and most recently for posts on Twitter and other social media concerning Covid-19.

Feel free to look up any of my tweets from 2021 and what you will find is that I shared articles by numerous doctors, scientists, and politicians who had serious reservations about lockdowns, face masks, the folly of distancing, and the experimental “vaccines”. At that time I also criticized the lack of freedom of choice in health care. (Twitter handle: @drzoltanrona)

Eventually, a former patient whom I had not seen in over 20 years read my tweets in 2021 and complained to the CPSO that I was steering people away from being vaccinated.

My stance on natural immunity was also controversial because I became convinced by scientific studies and my experience with patients that natural immunity is superior to the Covid-19 vaccine. (Mainstream media ignores studies proving this fact.)

The College of Physicians and Surgeons of Ontario then began questioning me along with my staff about my attitude toward vaccines. We told the CPSO investigators that we believe in freedom of choice in vaccination and that most of our patients refused the jabs for a variety of reasons like side effects and reports they had read about vaccine injuries.

I was then referred to a disciplinary hearing on charges of misconduct in November, 2022. In 44 years of practice, I had never experienced that. I had always assumed that Canada was a country that encouraged free speech based on what was law in the Charter of Rights and Freedoms.

Healthcare Professionals and Patients Pressured by Government

What bothered me most, and what concerned the vast majority of my patients, was the pressure they experienced from medical authorities to get the jab or lose their jobs, their ability to travel, visit restaurants and movie theaters, and even to visit doctors’ offices. One of my patients, who bowed to the pressure, died in his sleep a few days after receiving the Covid-19 vaccine. Another patient, whose cancer had been in remission, died suddenly after her cancer spread rapidly immediately following her second Covid-19 vaccine. (“Turbo cancer” is increasingly recognized as a side effect of vaccination.)

Several patients told me that their doctors refused to see any unvaxxed patients even if they had no Covid symptoms. This was despite multiple sources, including Dr. Anthony Fauci, declaring that the Covid-19 vaccines do not prevent viral transmission.

One section of the Charter guarantees freedom of choice in health care. By law, citizens cannot be forced to accept any medical treatment that they do not want. For example, if you have cancer, you are allowed to refuse chemotherapy. If you have diabetes, you can refuse insulin injections. Millions of Canadians do so every year.

The choice about whether to be injected with the Covid-19 vaccines, however, was denied to citizens during the pandemic and forced upon the medical profession to supply the jabs and all the boosters. Doctors were not allowed to provide exemptions, and were encouraged to push the jabs on their patients.

None of this was acceptable to me since it violates the Hippocratic oath (“First do no harm”) as well as the Canadian Charter of Rights and Freedoms.

In the end, it’s the public that has the most to lose as their rights and freedoms are stripped away. Instead of receiving unbiased, well-rounded health guidance from doctors, patients now receive only the pharma-approved dogma that feeds industry profit. Freedom of choice in healthcare no longer exists.

Access to Life-Saving Ivermectin Forbidden

In 2015, scientists William Campbell and Satoshi Omura received the Nobel prize for their discovery of Ivermectin, a broad spectrum anti-parasitic drug. In the award ceremony speech, Prof. Hans Forssberg of Karolinksa Institute addressed Campbell and Omura, stating, “Your discoveries represent a paradigm shift in medicine, which has not only provided revolutionary therapies for patients suffering from devastating parasitic diseases, but also promoted well-being and prosperity for individuals and society. The global impact of your discoveries and the resulting benefit to mankind are immeasurable.” (Dr. Simon Goddek)

In the years that followed, researchers found that Ivermectin was effective against numerous viral infections as well. Some studies even indicated that it worked to prevent and clear Covid-19 infections, when combined with zinc. (See Frontline Covid Care Alliance and Dr. Levy references below.) Despite this, the mainstream media attacked it as a de-worming drug suitable only for animals. The media further reported that Ivermectin was unsafe and ineffective for humans.

When I was questioned by the CPSO, they asked me whether or not I had prescribed Ivermectin for Covid. Since no pharmacy would allow the prescription, my hands were tied in writing Ivermectin prescriptions. By the way, Ivermectin is a derivative of an herb known as Wormwood (artemisia annua) which is also shown to be effective against viruses and parasites. Many countries (e.g. Madagascar) have been advocating Wormwood as a treatment for Covid infections as well as parasites.

There is also some evidence, mostly from animal studies, showing that Ivermectin has anti-cancer properties.

What I prescribed instead of Ivermectin were the key nutrients recommended in my Vitality article on “Coronavirus Prevention and Treatment.” These included:
1. Vitamin D3/K2 for clearing inflammation and building immunity to colds, ‘flus, and viruses;
2. Iodine for killing a broad range of pathogens while strengthening immunity;
3. Vitamin C for its antiviral and immune-enhancing effects;
4. Probiotics for replenishing the microbiome and nourishing the immune system;
5. Curcumin, an extract of turmeric, for its antiviral, antibacterial, antifungal and anti-parasitic activity.
(Editor’s note: See the article in reference section for the complete list of recommended supplements.)

Vitamin C can help to prevent a serious Covid infection, or if taken when infected it can reduce the symptoms / duration of illness

One chiropractor used my Vitality magazine articles on Covid prevention in 2021 to recommend various supplements to her patients. She was then reported to her College and faced an investigation. Thankfully she was acquitted of professional misconduct, so it seems like the chiropractic profession has some semblance of sanity in place.

Covid Prevention and Treatment Advice Heavily Censored

In the early months of the pandemic, I wrote several articles for Vitality magazine on natural Covid-19 treatments. I also posted these on my website ( Shortly afterwards, I received a 4-page letter from Health Canada demanding that I remove the articles from my site because they were advocating unproven remedies like vitamin D, vitamin C, zinc, quercetin, N-A-C, iodine, intravenous vitamin C, selenium and others.

Not wanting to end up in court while wasting time and money on legal defense, I opted to remove the articles from my website. Two years later Health Canada sent me another letter threatening prosecution for recommending natural cancer remedies. This was despite numerous published studies on the benefits of remedies like curcumin, IV vitamin C, and many other proven remedies that support cancer victims. Once again I was forced to remove those articles. (Editor’s note: These articles do still remain in place on Vitality’s website.)

Censorship like this used to exist in Nazi Germany, the Soviet Union, and still exists in Communist China. Authors of articles on alternative remedies are regularly jailed in those countries or somehow punished. Assassination attempts are often successful against those daring to fight back.

Here in Ontario, several medical doctors have been placed under investigation by the CPSO, and some have been suspended. A few of these MDs have launched court challenges. So far, none have been successful, and I don’t think any of them will be.

“The COVID-19 national emergency officially ended earlier this month — but censorship and silencing of criticism clearly have not.” Robert F. Kennedy Jr. (April, 2023)

Reports of Vaccine Damage Suppressed

In my view, it is unwise to believe what the government tells you about healthcare. The system is strongly biased against freedom of choice and patient privacy (e.g., vaccine passports, medical history privacy, and censorship on social media and mainstream media, etc.). I have come to believe that we are living in a censorship state orchestrated by the drug companies.
Regarding Covid vaccination, reports of vaccine injuries have been censored and the media has failed to report the truth about vaccine safety and efficacy. It has also failed to report that natural immunity experienced by those who recovered from Covid is proven to be more effective than any of the available vaccines.

I recently came across an article which listed 1,000 scientific studies demonstrating that the mRNA Covid-19 vaccines can be lethal. Of course, the mainstream media and the usual government spokespeople have attempted to censor this information even though it was published in hundreds of peer reviewed scientific journals.

The article was dated January 5, 2022 and it is more than likely that the number of studies by now have validated the superiority of natural immunity over the mandated jabs. This is important life saving information. Doesn’t the medical profession want to save lives?

Why I Gave Up My Medical License

I chose to give up my medical license on Nov. 5, 2022. After I stopped working for the government, I opted to continue advising clients who came to see me about improving their health through diet and supplements. There is far less stress on me now that I no longer write drug or hormone prescriptions. And my understanding is that there are many more doctors planning to give up their licenses in the near future.

At my office, I have a naturopath on staff for the benefit of patients who need certain lab tests and bioidentical hormone prescriptions. If patients need intravenous vitamin therapies, then the naturopath refers them for that service.

It’s been a complex and difficult job changing the way I’m operating but so far, it’s been successful. Feel free to make an appointment to see me for wellness counseling and advice on diets and supplements. I’ll continue to write articles for Vitality so stay tuned for that.

    Thank you for that article, Dr. Rona. I would like to suggest a book for you: Covid vaccinations: A Spiritual Perspective written by Thomas Mayer. It is on Amazon, and also Amazon has a kindle version for $17. Originally written in German, it is now available in English. It would support you in your decisions and open up a door as to the real purpose of the vaccination and creation of the covid virus.

    Your articles have consistently shown excellent insight into challenging healthcare topics. I read your articles with relish and I have shared many of them. The limitations and censorship put on healthcare practitioners during this pandemic has been ridiculous and overreaching.
    Keep on teaching and helping patients and of course doing no harm with your natural protocols.

    Dr Rona is to be commended for his stance and remaining true to the oath he took to First Do No Harm. It takes a lot of courage to stand up to the College of Physicians & Surgeons. I know of cases other than covid where they have interfered with alternative treatments and hounded doctors who practice them – even though these treatments are accepted in the US and many other parts of the world and have better results. I speak from experience – my own files were taken when my doctor’s office was raided and I was questioned by a College lawyer. Money, Power and Big Pharma corrupts.
