Online scammers have a new offer for you: Vaccine cards

On Etsy, eBay, Facebook and Twitter, little rectangular slips of paper started showing up for sale in late January. Printed on card stock, they measured 3-by-4 inches and featured crisp black lettering. Sellers listed them for $20 to $60 each, with a discount on bundles of three or more. Laminated ones cost extra.

All were forgeries or falsified copies of the Centers for Disease Control and Prevention vaccination cards, which are given to people who have been inoculated against COVID-19 in the United States.

“We found hundreds of online stores selling the cards, potentially thousands were sold,” said Saoud Khalifah, the founder of Fakespot, which offers tools to detect fake listings and reviews online.
