Here is a warning information tweet from the department of Health and Social care regarding a fake Covid19 Vaccine and charges on the Covid19 vaccine.
From the screenshot
A fraudster claiming to work for the NHS injected a 92-year-old woman with a fake #COVID19 vaccine.
The NHS will not ask you to apply for the vaccine and there is no charge for it. When it’s your turn, the NHS will contact you to book your appointment.
