According to the Better Business Bureau, scammers are calling people looking for Medicare or Medicaid info and trying to sign people up to get a vaccination.

The BBB says scammers are also promising to get you higher on a vaccination list if you give them money.

Remember, the vaccination is free, and if you’re looking on the web to sign up for the shot, look for the “dot org” at the end of the website. It’s an indication the site is legitimate.
