"No. Receiving a COVID-19 vaccine will not make you magnetic, including at the site of vaccination which is usually your arm," the US Centers for Disease Control and Prevention (CDC) has had to confirm on its website. (The bold "No" is by them, not us, FYI.)

"COVID-19 vaccines do not contain ingredients that can produce an electromagnetic field at the site of your injection. All COVID-19 vaccines are free from metals such as iron, nickel, cobalt, lithium, and rare earth alloys, as well as any manufactured products such as microelectronics, electrodes, carbon nanotubes, and nanowire semiconductors. In addition, the typical dose for a COVID-19 vaccine is less than a milliliter, which is not enough to allow magnets to be attracted to your vaccination site even if the vaccine was filled with a magnetic metal," the CDC says.

Of all the false claims about vaccines circulating online, the idea that they could make you magnetic is one of the funniest and one of the easiest to debunk. Merely fetch yourself a magnet, or something magnetic, and place it anywhere on your body. Try the site of your vaccine if you have had one, just to be sure.

The reason magnets are apparently sticking to people in several videos about this magnetic vaccine magic (which we're not linking to because they're a public health hazard) is that the person in question is sticky. Either they are naturally oily, or they have used some sort of adhesive to make the objects stick to them for their video. This has then been repeated by others and turned into a full-blown COVID-19 conspiracy.

Here's where things take a silly turn. 

This week, nurse Joanna Overholt, who is anti-vaccines, was testifying before the Ohio House health committee to "warn" of the dangers of vaccines. She undermined her own testimony somewhat when she attempted to prove that she was now magnetic.

"I just found out something when I was on lunch, and I want to show it to you," she told the committee. "You were talking about Dr [Sherri] Tenpenny's testimony about magnetic vaccine crystals? So this is what I found out. I have a key and a bobby pin here. Explain to me why the key sticks to me."

We already said, your skin is oily.

"It sticks to my neck too," she said, before failing to stick her key and bobby pin to her neck, because it wasn't as oily as her chest. "So yeah, if someone could explain this, that would be great," she finished. "Any questions?"

We expect there were many.

Dr Sherri Tenpenny, who is also anti-vaccine, has made a number of false claims about COVID-19 vaccines, including that they would make forks and spoons stick to people, as well as the trusty conspiracy classic that vaccines are somehow tied to 5G.

None of which is in any way true.
