An eBay account in the US has reportedly sold more than 100 fake vaccination cards in the last two weeks - despite the FBI warning doing so is illegal.
The Washington Post attempted to contact the seller via their account, which is linked to a Chicago area pharmacist. But the person told the Post they were unaware of the account and hadn't used it in months.
In a statement in March the FBI warned Americans to be on their guard for people selling the fake cards.
"The Department of Health and Human Services, Office of Inspector General and the FBI are advising the public to be aware of individuals selling fake COVID-19 vaccination record cards and encouraging others to print fake cards at home.
"By misrepresenting yourself as vaccinated when entering schools, mass transit, workplaces, gyms, or places of worship, you put yourself and others around you at risk of contracting COVID-19."
The agency also warned people against posting their completed vaccine cards on social media as it puts them at risk of identity theft.
The vaccine card, given after people in the US receive their first shot and then updated if their vaccine requires a second one, includes the vaccine manufacturer, the dose numbers and the date and location each was administered.
A spokesperson for eBay and Shopify previously told Insider that they are taking action against the scammers.
