Are COVID Vaccines Tested on Animals?

Last updated: June 6, 2022

The COVID pandemic has been in full swing for over two years now, and scientists believe the virus won't be going away any time soon. Thankfully, several vaccines have been developed to help protect people from the virus. But are these vaccines tested on animals first?

The answer is a bit complicated.

In this article, we'll discuss:

Keep reading to learn more about the COVID vaccine and whether or not it is tested on animals.

What is the COVID Vaccine?

Currently, there are three main types of COVID vaccines that have been developed and approved for emergency use in the United States:

  • Pfizer-BioNTech
  • Moderna
  • Johnson & Johnson

These vaccines are all mRNA vaccines, which is a newer type of vaccine technology. Though this type of vaccine only became widely known by the public thanks to the COVID pandemic, mRNA vaccines have been in development for over two decades.

An mRNA vaccine works by injecting a person with a piece of the virus’s genetic material. This genetic material contains the instructions for making a protein found on the surface of the virus. Once injected, the person’s cells read the instructions and produce the viral protein. The body recognizes that the protein is not supposed to be there and starts to build an immunity to it.

It's important to note that the mRNA vaccines are not made with fetal cells, which is a common misconception. In fact, no human cells are used in the manufacturing of these vaccines at all.

What is mRNA?

mRNA is short for messenger Ribonucleic Acid. It is a molecule that helps carry the genetic instructions of a gene from the DNA to the ribosome, where proteins are made. mRNA never has direct contact with DNA and does not enter the nucleus of a cell.

Are COVID Vaccines Tested on Animals?

All three currently available COVID vaccines were tested on animals before they were approved for human use. Specifically, they were tested on mice, hamsters, and primates.

Yes, all three currently available COVID vaccines were tested on animals before they were approved for human use. Specifically, they were tested on mice, hamsters, and primates.

The U.S. Food and Drug Administration (FDA) requires that before promising vaccine candidates can move on to human clinical trials, they must first demonstrate that they are safe and effective in animal models.

This helps to ensure that the vaccine is unlikely to cause serious harm to humans and that it actually induces an immune response that can protect against the virus.

After a vaccine candidate has been shown to be safe and effective in animal trials, it can then move on to human clinical trials.

A common misconception is that the COVID vaccines were rushed past the animal trial stage and into human trials. However, this is not the case. All three vaccines went through the complete animal trial process before being approved for human use.

There are ethical debates about whether animal testing should be used for medical purposes. As science advances, there is hope that research will soon be able to move away from animal testing altogether. However, it is currently the only way to ensure that a vaccine is safe for human use.

COVID Vaccine Side Effects

The most common side effects of the COVID vaccine are mild and temporary. They include:

  • pain and swelling at the injection site
  • fever
  • body aches
  • fatigue
  • headache

These side effects are all signs that your body is building immunity to the virus and are nothing to be concerned about. In fact, they are actually a good sign!

Rarely, some people may experience more severe side effects after getting the vaccine. These side effects include:

  • hives
  • wheezing
  • swelling of the face and throat
  • trouble breathing
  • dizziness
  • palpitations

If you experience any of these side effects after getting the vaccine, it is important to seek medical attention immediately.

FAQs

Do I need to get the vaccine if I’ve already had COVID?

Yes, it is recommended that you get the vaccine even if you’ve already had COVID. This is because there is currently no evidence that people who have had COVID are immune to reinfection.

As the virus continues to mutate, it is possible that people who have had COVID could be infected with a new strain of the virus. Getting the vaccine will help to protect you from these new strains.

Do the vaccines contain animal products?

No, the vaccines do not contain any animal products. They are made with synthetic mRNA that is produced in a lab.

Is the vaccine safe for pregnant women?

Current evidence suggests that the vaccine is safe for pregnant women, and the American College of Obstetricians and Gynecologists (ACOG) recommends that pregnant women be offered the vaccine.

They also state that the decision to get the vaccine should be made on an individual basis after weighing the risks and benefits.

If you are pregnant and considering getting the vaccine, it is important to speak with your healthcare provider first.

Does Botox affect the COVID vaccine?

No, Botox does not affect the COVID vaccine. This is because Botox is a protein that works by binding to nerve cells and prevents them from sending signals to the muscles. The COVID vaccine does not work in the same way, so the two do not interfere with each other.
