Volunteers for a research lab could earn £750 for taking part in a trial to find a cure for Ebola.
Participants at Hammersmith Medical Research centre will be injected with the disease which still affects large parts of the west African population.
The London trial, which begins in November, are looking for volunteers between 18 and 65 to take part in an experiment where proteins from the virus are injected into the person to trigger an immune response.
Volunteers took part in a previous experiment held by Oxford University in September.
There is currently no tested vaccine, no cure, and it kills 90% of infected patients.
In the advertisement, the centre wrote:
"Interested in helping medical research into a vaccine for Ebola and being paid for your help?
"The current outbreak of Ebola in West Africa is estimated to have caused more than 10,000 deaths, and is still ongoing.
"There is no specific treatment or cure for Ebola.
"We hope that the study vaccine will prevent people becoming infected with Ebola."
Visitors would have to make around 12 visits and it could take around a year for it to be completed.
Since February 2014, more than 11,000 people across Sierra Leone, Guinea and Liberia have died as a result of Ebola.
But the leaders of the Hammersmith Medicines Research would like to reassure those interested in taking part in the trial there is no risk of catching Ebola by taking part in the study.
