The FTC has issued another warning to watch out for vaccine scams. This time, it's a simple one: COVID-19 vaccine shots are free - so if someone tries to charge you money for one, it's a scam. The agency encourages you to ignore any online ads or social media posts offering to sell you the vaccine, and warns never to share personal or medical information with people you don't know. State and local health departments are the most reliable way to find a vaccine shot. All U.S. adults are eligible to receive the vaccine as of this week. Seriously, who would scam a vaccine?
