A scathing letter which demanded Freedom Day be delayed and was backed by more than 1,200 'experts' allowed people with no scientific credentials to sign it, MailOnline can reveal.
The document accused the UK Government of conducting a 'dangerous and unethical experiment' by pressing on with the July 19 unlocking despite soaring infection rates.
It was originally signed by 122 leading scientists and doctors last week and published in the prestigious journal The Lancet.
But it was later republished on an online campaign website, where it gained more than 1,000 more signatures and made national headlines on Tuesday.
The Lancet's editor-in-chief Dr Richard Horton claimed that the letter highlighted that there was 'no scientific consensus' over Boris Johnson's decision to ditch most remaining lockdown curbs next week.
However, among the 1,246 purported scientists who'd put their name to the document by last night, MailOnline found social workers, midwives, dentists and trainee doctors.
There were also a handful of signatories who simply had 'medic' as their profession or a blank space beside their name.
MailOnline was able to sign the letter using a fictitious name and title, however, the pseudonym was not added to the published list of signees at the time of writing.
The document attacked the Government over policy that will have economic and health impacts England, and more widely Britain — yet people from all over the world were able to sign it.
MailOnline counted dozens of names from as far afield as New Zealand, Australia, India and Japan. Signees were also located in Mexico, the US, Canada and Argentina, as well as several countries around Europe.

Dr Simon Clarke, a microbiologist from the University of Reading, told MailOnline that allowing people who were not scientists or practicing medical professionals within the UK to sign the letter was 'misleading'.
He added the UK was in a 'unique position' to most countries around the world because of its highly successful vaccination rollout, which gives it the luxury to be one of the first countries to relax Covid curbs fully.
'I think think asking people who are not working or practicing in uk to comment on policy which is English but may have ramifications for other parts of the UK is potentially misleading.
'And I don't think right if we [British experts] were to comment on country specific policies elsewhere in the world it would be particularly welcome.'
In the Lancet letter, the original 122 experts demanded the Government reconsider its plan to abandon all restrictions in England on Monday, describing it as 'premature'.
They warned that going ahead with Freedom Day despite accepting there could be hundreds of thousands of infections each day is both 'unethical and illogical'.
Allowing Covid to rip through the country will leave 'hundreds of thousands with long-term illness and disability' due to the effects of the virus itself, as well as long Covid, they said.
Among the original signatories were Sir David King, a former chief scientific adviser under David Cameron's Government, and Dr Chaand Nagpaul, chairman of the British Medical Association (BMA) Council.
The letter was also signed by several of No10's own expert advisers, including Professor Susan Michie and Professor Stephen Reicher, highlighting the rift within SAGE over the July 19 unlocking.
After its original publication in the Lancet on July 7, the letter was then post to the John Snow Memorandum website, which was set up by medics and scientists who oppose Laissez-faire attitudes to Covid curbs.

Dr Clarke told MailOnline: 'While some of these people will have opinions, and while those opinion might be valid, they shouldn't be presented as scientists and medical experts.
'I'm a microbiologist, I'm not an expert in delivering babies, so I wouldn't put my name to a pressure letter
