Electric and magnetic fields (EMFs) are areas of energy that we can't see. Examples of EMF sources include sunlight, microwaves, cell phones, power lines, and wireless networks.

There are two types of EMFs. One is called non-ionizing EMF, which is low-level radiation that's considered generally harmless to humans. The other is called ionizing EMF, which is high-level radiation that has the potential to harm human cells or DNA. Sunlight is an example of ionizing source of EMF, and all of the rest of the examples above are non-ionizing sources of EMF.

Only certain levels of radiation can trigger high levels of EMFs. Importantly, no vaccine approved for emergency use contains any metals or radiation technology that would produce such levels.

The Pfizer vaccine, for instance, is made up of mRNA, lipids, potassium chloride, monobasic potassium phosphate, sodium chloride, dibasic sodium phosphate dihydrate, and sucrose. Ingredients for the Moderna vaccine are similar. The Johnson & Johnson and AstraZeneca vaccines are also made of common vaccine ingredients, but use a different part of the virus to get our bodies to launch an immune response. None of the ingredients in any of the vaccines are ionizing or non-ionizing sources of EMF. 

Radiation therapy that's used to treat some cancers uses high-energy beams such as x-rays to help kill bad cells. These types of treatments are known to be a source of EMF, but scientists have determined that for many people the benefits of radiation treatment outweigh the risks.

All people and objects emit some (usually low) level of EMF radiation. In people, this is because of tiny electrical currents in our bodies. The currents come from chemical reactions that are part of normal body functions. A number of things could increase someone’s EMFs levels, such as radiation therapy, metallic implants, titanium implants, hearing implants, and more. When measuring EMFs, even objects nearby can set off a high reading. That's the case even if it's only slightly closer to an individual with a high reading than to an individual with a low reading.

Videos and stories have been circulating online of individuals using EMF readers to show low EMF readings on non-vaccinated individuals, higher EMF readings on bluetooth devices and wireless networks, and high EMF readings on vaccinated individuals at their vaccination site on their arm.

Any high EMF readings are likely due to other factors such as radiation therapy, an implant, or other devices nearby. In addition, these claims have no scientific basis. The "experiments" conducted in the videos and anecdotes were not scientifically controlled or conducted with scientific rigor.

The COVID-19 vaccines get injected deep in our muscles and over time, the ingredients move through us to strengthen our immune system. Some people may experience localized inflammation and/or soreness on the injected arm, which lasts for a few days and has been listed by the CDC as a possible temporary side effect. People will not experience EMF radiation at the injection site beyond the normal level, unless there are other factors at play such as cancer radiation, or an implant.

Magnetized proteins, or "magnetoproteins," are not included in the ingredients of any COVID-19 vaccines authorized by the World Health Organization (WHO).

A 2016 article from The Guardian discussed genetically engineered magnetized ('Magneto') proteins which were inserted into a virus and then put into living animals. Scientists tried to activate nerve cells in these animals after the protein went through a complex and multi-step development process in a laboratory. These experiments were not performed in human beings and no attempts at activating nerves in the brains of humans occurred. These magnetized proteins are not found in COVID-vaccines authorized by the WHO. Vaccines for COVID-19 do not contain ingredients that could produce an electromagnetic field.
