As vaccination rates rise there is a new threat coming about - fake vaccination certificates.
Being vaccinated is becoming a requirement for travel, and in some cases college education. Those requirements are expected to multiply as vaccine supply grows.
Connecticut's attorney general says there is a new shady scam popping up on the internet - people selling fake vaccination certificates.
Officials from 45 states are joining together to ask websites including Twitter and eBay to crack down on this criminal enterprise.
"It is a lie that can get people hurt and can get them killed," says Connecticut Attorney General William Tong.
EBay has put out a statement saying it is doing everything it can to crack down on these sellers.
