A university student says she is planning to return to the UK after taking an unproven coronavirus vaccine.
Evelyn Wu, 20, said she paid £50 to have the vaccine in her homeland of China last week.
The University of Birmingham student said she jumped at the chance to take it, even though it hasn't been scientifically proven.
Ms Wu went to the hospital in Yongkang, eastern China to register and had the vaccine two days later.
She is now hoping to return to Birmingham in January to carry on with her economics degree.
Admitting her "excitement", Ms Wu said: "It's just like a normal vaccine."
She said: "I needed to sign some contract. It has the details about Covid-19. And it told me that it's very safe, even though it's only stage 3."
"I'm a little worried about [it being] experimental stage 3," Ms Wu told Sky News.
"And I think I was the one who was the test subject, the one who was treated like a little mouse."
But she added: "I trust China and I think it's totally safe to get vaccinated. I trust the government.
"But some doctors and some teachers refused to take the vaccination. They think it's dangerous because they think they are being tested.
"They don't want to be the volunteer to get the experimental vaccine."
Ms Wu flew back to China at the request of her mother back in March.
"She is happy for me to have the vaccination," she said.
"Because she thinks I am brave. I make an example for others.
"Because there is an old saying, the first one to eat the crabs is the most brave, right?"
The UK could become the first nation to carry out human challenge studies, in which healthy people will be intentionally exposed to the virus responsible for Covid-19 in order to test the effectiveness of different vaccine candidates.
The Government is putting £33.6m towards the research, with trials set to begin in early January 2021.
At present, there are more than 240 coronavirus vaccine candidates being tested around the world.
It comes after the Government's chief scientific adviser Sir Patrick Vallance warned a vaccine won't be ready until spring next year.
Sir Patrick added it is “unlikely” that a coronavirus vaccine will stop the disease completely.
Giving evidence to the joint Commons and Lords National Security Strategy Committee, Sir Patrick said that only one disease – smallpox – had ever been completely eradicated.
But Sir Patrick said they “may” be some doses before that, but it remains to be seen.
He also warned that that in future, treating Covid-19 may become more like seasonal flu.
“I think it is unlikely that we will end up with a truly sterilising vaccine that completely stops infection,” he said.
“It is likely that this disease will circulate and be pandemic. My assessment – and I think that’s the view of many people – is that’s the likely outcome.
“Clearly as management becomes better, as you get vaccination that will decrease the chance of infection and the severity of the disease – or whatever the protocols of the vaccines are – this then starts to look more like annual flu than anything else and that may be the direction we end up going."
