It describes a COVID-19 outpatient protocol first proposed in 2020 by the late Dr. Vladimir Zelenko, alongside what current clinical research (through 2026) shows about each component . Hydroxychloroquine and ivermectin are prescription-relevant medicines with real drug interactions and side effects; large randomized trials completed since 2021 have not shown a meaningful treatment benefit for COVID-19 (details below), and neither drug is recommended for this use by the FDA, WHO, or NIH COVID-19 Treatment Guidelines.

In May 2026, a resurfaced video from the late Vladimir Zelenko (“Dr. Zev” Zelenko) went viral again on X, generating more than 1.5 million views and reigniting debate about zinc, vitamin D, and low-cost antiviral strategies. In the 2-minute clip (video below), Zelenko explains a concept he promoted heavily during the COVID-19 pandemic: many dangerous viruses share the same replication machinery, and therefore may share similar therapeutic vulnerabilities. The video specifically references: COVID-19 Influenza RSV Ebola virus disease Marburg virus disease Hantavirus infections His argument centers on zinc, zinc ionophores, and RNA-dependent RNA polymerase (RdRp), the enzyme many RNA viruses use to replicate. But does the science support the claim? Here’s a balanced, evidence-based review. What Is Hantavirus? Hantaviruses are rodent-borne RNA viruses that can cause severe human disease. Depending on the region and viral strain, infection may lead to: Hantavirus Pulmonary Syndrome (HPS) H...

As of April 2024, more than 35 studies on the topic of zinc and COVID-19 ( c19zinc.com ) and more than 10 studies on quercetin and COVID-19 have been published ( c19quercetin.com ).  Quercetin is a natural antihistamine and anti-inflammatory plant pigment that boosts your immune system and may work to control viral replication, according to some research. It allows zinc to exert its proven antiviral properties; in treating COVID-19, quercetin may also lower inflammation, help clear mucus, prevent ventilator-induced damage and support immunity. According to the research, quercetin has been shown to help fight obesity, Type 2 diabetes, circulatory dysfunction, chronic inflammation and mood disorders. It has even been found to help lower blood pressure. Researchers have found that quercetin can trigger tumor regression and begin the process of apoptosis. This is programmed cell death, without which cells can grow uninterrupted and develop into cancerous growths. In 2003, Que...

Dr. Zelenko’s main hypothesis based on the data showing that early intervention and treatment of high-risk patients with COVID-19 results in significantly few hospitalizations and deaths. This treatment regimen involving zinc, low-dose hydroxychloroquine, and azithromycin is also apparently known as, “The Zelenko Protocol.” Update:  Recently, Ivermectin has come to the fore as a more effective (also long standing, cheap, generic drug), in all three stages of COVID-19. Dr Zelenko has also updated his protocols to incorporate ivermectin as an option for both the prophylactic and treatment protocols as shown below. Zelenko Covid-19 Prophylaxis Protocol Prophylaxis is an action taken to prevent or protect against a specified disease. Greek in origin, from the word "phylax", meaning "to guard" and "watching."     Low Risk Patients Young healthy people do not need prophylaxis against Covid 19. In young and healthy people, this infection causes mild cold-like sym...

Z-Stack is a multivitamin developed by Dr. Vladimir Zelenko, MD — a physician known for developing the " Zelenko Protocol " for treating and preventing COVID-19. The protocol has as its centerpiece, but not exclusive piece, the combined use of Hydroxychloroquine (HCQ) and Zinc as a means by which a person can both help to prevent or mitigate the contraction of COVID-19, or can actually treat the disease once it has been diagnosed.  A  retrospective study  analyzing Dr Zelenko's patient data was accepted for publication after a rigorous peer review process. The study finds that early intervention and treatment of high-risk patients with COVID-19 resulted in significantly fewer hospitalizations and deaths. The treatment consisting of zinc, low-dose hydroxychloroquine (HCQ), and azithromycin, is also referred to as "The Zelenko Protocol." Dr Zelenko has since updated his protocols to incorporate new evidence. He has since evolved his protocols to include a querceti...
