For most of us, being notified that you were to receive your Covid-19 vaccination was a moment of relief.
But for some, it was the start of an ordeal that has cost people all over the UK more than a third of a million pounds.
Sioban Moore, from North Yorkshire, escaped disaster by a whisker after receiving an email, supposedly from the NHS, inviting her to get her jab.
A retired children's social worker, Sioban has been helping to drive people to hospital appointments and collect shopping for people during the pandemic.
Because of her volunteering work with vulnerable people, the email was just what she had been waiting for.
"I was very keen to accept the invitation," she told BBC Radio 4's You and Yours.
The message told her that unless she responded within 12 hours, the opportunity would go as the offer would be given to someone else. Eager to receive her vaccination, Sioban followed the link and accepted the invitation.
Personal details were then requested: date of birth, phone number, email address - and her bank details.
'The penny dropped'
Sioban found the reasoning for this request for her bank details strange, but believable, as the scammers said this was to cover any costs that might be incurred by the vaccine process.
"I got up and went to my purse and got out my credit card. I looked at it and the penny dropped massively," she said.
Luckily, Sioban realised it was a fraud just in time and didn't lose any money. Many people have not been so lucky and have been taken in by these scams.
