[Homework]2014-09-20 英国展开埃博拉疫苗人体试验 志愿者接受注射

Are you happy to go ahead? Do you have any questions?
Without a hint of nerves the first person to have an experimental Ebola vaccine takes the plunge, R is one of 60 healthy volunteers in Britain to be given a jab as part of clinical trial, and she is paid just 380 pounds, not for the risk, but for any loss of earnings, the vaccine has clearly tested in monkeys, but scientists need to be sure it's safe and effective before using it on the front line of the Ebola epidemic.
My 15 year old son he thought I was Ebola having, and he asked was i going to die, and where is my *, my 12 year old daughter was concerned but said well done mum for what you are doing, this is one step but i'm part of that first step, and it gets some vaccine, they know they got the right vaccine, then they can start giving it, and that's going to make a difference to people's lives.
The vaccine is made from a harmless virus common in chimpanzees, that's been modified to carry a small piece of Ebola DNA, once in patients the virus will make a single Ebola protein, it won't cause the disease, but it should be enough to prime the immune system to attack the Ebola virus if it's ever encountered in future.
The good thing about the vaccine is it probably doesn't need to work for five years or even five months, if it had higher * for two or three months that would be very valuable, and technically that's easier to do and to make the vaccine that works for a decade.
Volunteers will be given varying amount of the vaccine to fight a dose that triggers good immune response without causing serious side effects. Normally it would take 18 months or more for a vaccine to go through clinical trials, but such is the desperate need to protect health workers who are putting their lives on the line by treating Ebola patients, that this one is being fast tracked, even while clinical trials are under way, G is producing 10,000 doses, ready to be sent out to west Africa as soon as they get the green light.
But there won't be anywhere near enough the vaccine for local people, the Ebola epidemic is out of control in Serra Leone and Liberia, and the doctor who discovered the virus told Sky news that thousands of people are still likely to die.
One of the lessons is that of this epidemic is that we need to make sure that we accelerate the ways that we test and evaluate drugs, vaccines also, if we had done that in the beginning of the epidemic we would probably already have an answer.
Quarantine of patients and rapid tracing of their contact is currently the only way to beat the virus, the world health organization has welcomed the 3,000 US military personnel being sent to the region to build field hospitals with 1,700 beds, it's not enough, but it's a start.
Thomas Moore, Sky news.
