Idahoans Wonder and Test if the COVID Vaccine Really is Magnetic Is this harmless silliness, conspiracy, or truth? Some people believe the COVID vaccine is magnetic and that could mean a number of things for those who have been dosed. Could it be that the vaccine contains metallic microchips that give us better 5G reception since some think the 5G towers are the cause of the pandemic? Why do Some People Think the COVID Vaccine is Magnetic? There are numerous videos floating around the internet right now which appear to prove that the COVID vaccine is magnetic. Posts on social media sites from my friends and around the world show people who have just received the vaccine placing magnets on the injection site and having the magnet stick. This has caused a lot of speculation about the cause of the magnetism.
