Is Colloidal Silver Effective Against Virus?

Viruses represent one of the leading causes of disease and death worldwide. The Covid-19 pandemic, also known as the coronavirus pandemic, is an ongoing global pandemic of coronavirus disease 2019 (COVID‑19), caused by severe acute respiratory syndrome coronavirus 2 (SARS‑CoV‑2). The pandemic has caused an unprecedented global social and economic disruption, including the largest global recession since the Great Depression.


The current recourse to defend ourselves against virus is vaccination. Vaccines contain the same germs that cause disease. (For example, measles vaccine contains measles virus, and Hib vaccine contains Hib bacteria.) But they have been either killed or weakened to the point that they don’t make you sick. Some vaccines contain only a part of the disease germ. A vaccine stimulates your immune system to produce antibodies, exactly like it would if you were exposed to the disease.

After getting vaccinated, you develop immunity to that disease, without having to get the disease first. Vaccine stimulates the body’s immune system to recognize the agent as foreign, destroy it, and “remember” it. In this way, the immune system can more easily recognize and destroy any of these microorganisms in future encounters.

Movement against Vaccination

There is an increasing number of parents worldwide refusing to vaccinate their children due to numerous reasons and perceived fears. Parents hesitate to vaccinate their children for many reasons. The prominent parental concerns over the past decade have been that vaccines may cause autism in children and other harmful side effects in the long run.

Colloidal Silver and Virus

Silver nanoparticles (AgNPs) have been widely studied as an antimicrobial agent. Many of the studies conducted were mainly to investigate the effects of silver against bacteria. However there are also several studies that were done to investigate the effects of silver specifically against virus.

In a research conducted by Lei Lu, it was found that silver nanoparticles could inhibit the in vitro production of Hepatitis B Virus (HBV) RNA and extracellular virions. They hypothesize that the direct interaction between silver nanoparticles and HBV double-stranded DNA or viral particles is responsible for their antiviral mechanism. Their research report is titled Silver Nanoparticles Inhibit Hepatitis B Virus Replication and is published in the Journal of Antiviral Therapies 2008;13(2):253-62.

In another study by Humberto H Lara,, the mode of antiviral action of silver nanoparticles against HIV-1 was examined. Their results reveal, for the first time, that silver nanoparticles exert anti-HIV activity at an early stage of viral replication, most likely as a virucidal agent or viral entry inhibitor. They also found that there were no significant difference in the antiviral activities of silver nanoparticles against the different drug-resistant strains, which means, new HIV virus strains cannot develop resistance against silver. They also found that silver actually binds with the viral protein and denaturize it thus disabling its function. Their study is titled Mode of Antiviral Action of Silver Nanoparticles against HIV-1 and is published in the Journal of Nanobiotechnology 2010; 8: 1.

In research article titled Viral Pathogens and Severe Acute Respiratory Syndrome: Oligodynamic Ag+ for Direct Immune Intervention, published in the Journal of Nutritional & Environmental Medicine, Volume 13, 2003 – Issue 2, the author mentions that efficacy against the SARS-related coronavirus may be enhanced when nebulized Ag+ is inhaled. The author also says that the only known mechanism of resistance also appears to play no role notwithstanding the mutability of the coronavirus. Therefore no functional barrier to the virotoxic effects of oligodynamic Ag+ may be expected regardless of the rapidity or variety of mutations. The author aslo mentions that there is no known toxicity for Oligodynamic Ag+ in humans. Colloidal Silver for Hiv

In a review article titled Silver Nanoparticles as Potential Antiviral Agents, published in Molecules  2011 Oct; 16(10): 8894–8918, the researchers have summarized the effects of silver against various types of viruses which includes  Retroviridae (HIV), Herpesviridae (Herpes), Paramyxoviridae (Respiratory Syncytial Virus), Hepadnaviridae (Hepatitis B), Orthomyxoviridae (Influenza), Poxviridae (Monkeypox) and Arenaviridae (Tacaribe).

From the various research, it is found that silver can interact with the virus surface protein and alter its shape thus disabling its binding function to host cell. In addition to this, silver can also penetrate the cell walls of the virus, and interact with its genome (DNA and RNA) and prevent it from replicating. By inhibiting the binding and replicating functions of a virus, the virus can exert no harmful effects on humans.
