Giving Compass' Take:
• As the Ebola virus rages on in the Democratic Republic of Congo, debates are ongoing on whether or not doctors should deploy a second Ebola vaccine.
• One of the issues concerning the vaccine is that there is not enough to deal with the current outbreak. How can donors get involved?
• Read more about the debate over the second Ebola vaccine.
A debate is raging over proposals that a second vaccine be introduced to fight Ebola in Democratic Republic of Congo, currently in the grip of its worst outbreak.
The DR Congo Health Minister, Dr Oly Ilunga, who resigned after being stripped of management of the country's Ebola response, said the current vaccine is the only one that has been proven to be effective, and an opposition MP said the new vaccine is untested, and fears people in the country will be used as guinea pigs.
Leading health experts say the second vaccine is safe and could be an important tool in holding back the spread of the virus.
So what are the concerns, and are they justified?
It has been tested on over 6,000 people and "has shown outstanding safety," says Professor Peter Piot, a leading expert on Ebola and director of the London School of Hygiene & Tropical Medicine, which has been involved with pharmaceutical company Johnson & Johnson in the development of the vaccine.
Studies have shown that although the drug is still in the experimental phase, it has proved highly effective in tests on primates (animals genetically close to humans).
The only way to test its effectiveness as prevention measure for humans is for it to be used in an outbreak scenario.
It was rolled out for "compassionate use" which allows for the use of an unlicensed drug (licenses can take years or decades to get) when no other options are available, but only with authorisation from the government of the affected country.
If there's already a vaccine which has been proven effective against Ebola, why not just roll out more of it?
Dr. Josie Golding of the Wellcome Trust, says it's likely there won't be enough of the vaccine to deal with the current outbreak.
