If youâre thinking of sharing a post-vaccination selfie on social media commemorating the moment, think again. Experts say you could be inviting identity theft. A vaccination card contains sensitive information including your full name, date of birth, where you were vaccinated and the dates you got it. The Better Business Bureau warns of scammers using the information from your vaccination card to create and sell phony ones, in addition to other possible identity problems. The DeKalb County Transportation and Council on Aging encourages residents to keep their vaccination cards safe to avoid online and offline scammers taking advantage of the COVID-19 pandemic to steal personal information.
