From The Babylon Bee:

PHOENIX, AZ—Local man Greg Chandler is worried that the government might put a tracking device in the vaccine.
“The government is putting tiny tracking microchips in the vaccine, and they can spy on you no matter where you go! Don’t fall for this!” he wrote on the Facebook, Twitter, and Instagram apps. “We must stand up and say enough is enough! Big brother is watching you!”
He then recorded a short video rant which he posted to TikTok and checked in at the restaurant he was meeting some friends at.
At publishing time, the NSA agent watching Chandler through his smartphone’s front-facing camera had denied the man’s claims that the vaccine has any sort of tracking device in it.
