[In guidance] posted on Feb. 19, the CDC said adults 65 years of age and older — one of the first groups eligible to receive the jab — should be aware that COVID-19 vaccines are "free of charge" for those living in the U.S. "If anyone asks you to pay for access to vaccine, you can bet it’s a scam," the CDC said in the guidance. … Though the vaccine is free of charge, "your vaccination provider may bill your insurance for administering the vaccine," the CDC noted. "No one can be denied a vaccine if they are unable to pay this cost."
