Social media posts claim COVID-19 vaccines could contain trackers, citing a video showing a positive reading when a device designed to detect pet chips is held over the arm of a vaccinated woman. This is false; the person who posted the video subsequently described it as a joke, and US health authorities say the vaccines do not contain trackers.
"They are literally tagging and tracking everybody taking the Jab," says a June 24, 2021 Facebook post featuring the video.

In the clip, the pet chip reader -- used to identify lost animals -- is held over a woman's right arm and finds nothing, but returns a result when held over her left, in which she said she received her shot.
But the user later posted that the video was a joke, saying "it's obviously a dog chip" that was being detected.

The US Centers for Disease Control and Prevention says that COVID-19 shots do not contain trackers.
"No, the government is not using the vaccine to track you," it says in a frequently asked questions sheet.
"There are no trackers in the vaccines themselves. State governments track where you got the vaccine and which kind you received using a computerized database to make sure you get all recommended doses at the right time," the sheet says.
And Dr Jason Farley, a professor and nurse practitioner in the Division of Infectious Diseases at the Johns Hopkins Schools of Nursing and Medicine, told AFP on July 1 that there is no "chip in any... vaccine product."
According to fact sheets provided by health authorities in the US and Canada, none of the available COVID-19 vaccinations (Pfizer, Moderna, Johnson & Johnson or AstraZeneca) contain any metal-based ingredients.
