Desperate vaccine seekers turning to third-party websites, but are they safe? Some providers may ask you directly for your social security number but the BBB cautions you about offering it up to third-party websites. Author: Matt Caron Updated: 3:51 PM EST March 5, 2021 CROMWELL, Conn. — When it comes to the COVID vaccine, demand is still outpacing the supply. It's forcing people to turn to strangers for help booking an appointment. FOX61 called three different vaccine appointment booking lines. "No new vaccination appointments are available at this time," read a recording from UConn Health. "We are currently processing calls from Monday morning," read another message from Waterbury Hospital. The city of Waterbury's health department line said, "We will contact those who are on the waiting list and then open the phone lines to take more calls."
