Are these seven COVID-19 vaccine ingredients safe? OSHA, NIH, EPA and several chemical experts say “No”

Should you be injecting yourself with ingredients that are recognized as harmful for humans by multiple U.S. government agencies and chemical manufacturing experts? The choice is up to you, for now.

Since the COVID-19 vaccine rollout, the country’s opinion has been split into essentially two camps over the effectiveness and safety of the vaccine. One camp, generally associated with those left of center politically is that the vaccine options currently available are the safest and most effective vaccines to ever leave the lab. For the “other” camp, the consensus among most is that mRNA technology is untested or brings negative consequences relating to genetics, or that the ingredients around the mRNA may not be safe for human consumption.

Putting all opinions aside, this article will only cover the hard facts concerning what authoritative medical and government sources have said regarding some of the ingredients in either the Pfizer, Moderna or Johnson & Johnson/Janssen vaccine options that are currently available to the American public.

Starting from the top, the CDC created an infographic [ source] that outlines all of the ingredients in each of the currently available vaccines in the US.

We’ll include a screenshot here for a visual reference:

Our process of research involves finding any documents from an authoritative government, medical or scientific source that indicate ANY negative side effects for humans or animals.

Starting with the Pfizer-BioNTech ingredients:

Polyethelyene Glycol

Study published on [NIH source] about toxicity in mice when injected with Polyethelyene Glycol

Polyethylene glycol is listed as an item on the EPA’s TRI-Listed Chemicals (Toxics Release Inventory program).

In general, chemicals covered by the Toxics Release Inventory (TRI) Program are those that cause one or more of the following:

  • Cancer or other chronic human health effects
  • Significant adverse acute human health effects
  • Significant adverse environmental effects


Safety Data Sheet from Cayman Chemical indicating Acute Toxicity in multiple categories with a specific set of warnings including “May be fatal if swallowed, inhaled, or absorbed through the skin”


A safety data sheet published by Fisher Scientific indicates hazards for human health in the areas of Aspiration and Reproductive toxicity

Moving on to the Moderna ingredients:


A Safety Data Sheet from Cayman Chemical for a mix of SM-102 and Chloroform highlighted several health warnings including “Suspected of causing cancer.”, “Suspected of damaging fertility or the unborn child.”, and also “Causes damage to the central nervous system, the kidneys, the liver and the respiratory system through prolonged or repeated exposure.”.

On this ingredient, it is worth noting that has claimed that SM-102 is not actually dangerous, expressing that this SDS from Cayman Chemical was “misleadingly highlighted”, and that the version of SM-102 that is use in the Moderna vaccine has been refined to a level that is no longer dangerous to humans. An article by Yahoo reported that the health hazards were isolated to the Chloroform, and not the SM-102 itself.

Upon examining the SDS for Chloroform and comparing it to the SM-102 in Chloroform SDS, we found that the GHS classification increased from 2 to 3 when SM-102 was present. The SM-102 addition gains a number of warnings, including specifically “Causes damage to the central nervous system, the kidneys, the liver and the respiratory system through prolonged or repeated exposure.”, this warning is not listed on the SDS for Chloroform, but is listed on the SDS for SM-102 in Chloroform.

With this information, it is also worth noting that we were not able to find any notable studies on SM-102 or Safety Data Sheets of the compound solely by itself.


A Safety Data Sheet from Hospira, a Pfizer Company where Tromethamine was used as an injection anti-inflammatory drug provided a laundry list of health hazards.

Acute toxicity, oral-Cat.3; H301 – Toxic if swallowed
Acute toxicity, inhalation-Cat.3; H331 – Toxic if inhaled
Skin corrosion/irritation-Cat.1A; H314 – Causes severe skin burns and eye damage
Reproductive toxicity-Cat.1A; H360D – May damage the unborn child
Specific target organ toxicity, repeated exposure-Cat.2; H373 – May cause damage to organs through prolonged or repeated exposure

An additional SDS from Medisca cited similar health concerns for a product containing Tromethamine.

Acute Toxicity – Oral (Category 3)
Skin Irritation (Category 2)
Eye Irritation (Category 2A)
Toxic to Reproduction (Category 2)
Specific Target Organ Toxicity – Repeated Exposure (Category 1) (cardiovascular system, gastrointestinal tract)

Acetic Acid

A Safety Data Sheet from Fisher Scientific listed multiple hazards for flammability and corrosive. Overall Acetic Acid is listed as a Health 3, Flammability 2 rated ingredient on the HIMS scale.

Janssen ingredients


Ethanol, great for your car, but not your body according to this safety data sheet from Fisher Scientific. The most significant concern listed was the potential fertility damage or harm to unborn children.

A highlight of this reporting effort should be that many of the ingredients did not have existing safety data sheets, studies, or evaluations by regulating agencies.

[opinion] – Regardless of your stance of the safety of these vaccines, it’s easy to see how someone conducting their own research might see these warnings and become concerned.
