Parents and teachers have been warned about a hoax Covid vaccine consent form being circulated in schools and online.
The letter, which includes a fake NHS logo, contains a 'consent checklist' and a number of false assertions about the jab.
They include bogus claims the vaccine can cause miscarriages and blindness and that it's still deemed 'experimental'.
Parents revealed they had been sent the form via email and told to give it to their children before their vaccination appointment.
Some head teachers also reportedly received the letter and were asked to share it with their students.
An NHS England boss took to Twitter last night to denounce the letter as illegitimate.
The UK started vaccinating healthy 12 to 15-year-olds with a single dose of Pfizer's vaccine for the first time last week.
It did so despite originally not getting the blessing from No10's vaccines advisory panel, which said the health benefit to youngsters was 'marginal'.

REAL CONSENT FORM: The legitimate version available on the NHS England website
The Joint Committee for Vaccination and Immunisation (JCVI) left the decision to Chris Whitty and the chief medical officers in the devolved nations.
They signed off on the plans on the basis it could prevent hundreds of thousands of school absences.
Parent Ruth Moss, from Merseyside, posted a picture of one of the fake consent checklists on Twitter.
NHS England medical director for Covid immunisation Dr Jonathan Leach replied: 'Just to confirm that this is not a legitimate NHS form.'
It comes after the biggest survey of its kind suggested just half of children in England want a Covid vaccine.
Researchers surveyed more than 27,000 nine to 18-year-olds across the country earlier this year ahead of the move to jab healthy secondary school pupils.
Younger children were less willing to get vaccinated than older teenagers, of whom the majority said they would accept a jab. Youngsters who had previously tested positive or believe that they had Covid already were more likely to decline a vaccine
Researchers surveyed more than 27,000 nine to 18-year-olds across the country earlier this year ahead of the controversial plans to jab healthy school pupils. Exactly 50 per cent were willing to have the vaccine, while a third (37 per cent) were undecided and 13 per cent wanted to opt out
Fourteen-year-old Jack Lane became one of the first to benefit from the extension of Britain's jab rollout to children last week at Belfairs Academy in Leigh-on-Sea, Essex
