From Age Concern:
The Covid-19 vaccine will be offered free of charge. More information will follow in due course. Please be cautious when receiving phone calls, especially if asked for money or personal information.
We have been made aware of a phone call scam about the vaccine being for sale. The scammer calls to advise the vaccine is available for $49.99. You are given the choice to press 1 to continue or 2 to cancel.
This is a way to automate getting people on the line for a scammer to then get their credit card details, gain access to their computer or exploit them some other way.
