Recently there has been a message going around claiming to be from the NHS that tells recipients to click on a phony link (something like uk-application-form.com) to apply to get vaccinated. The link takes you to a very vaguely believable website that most likely is designed to steal card details and addresses.
This will be particularly dangerous for old people and people who believe they are currently eligible for a vaccine dose as they will be particularly vulnerable to COVID-19. I’m not sure what the official process for getting an appointment is, but it’s not this. Spread to who needs to see it.
