Coronavirus:US volunteers test first vaccine
The first human trial of vaccine to protect against pandemic coronavirus has started in the US.
Four patients received the jab at the kaiser permanente research facility in seatle, washington,report the associated press news agency.
The vaccine cannot cause covid-19 but contain a harmless genetec code copied from the virus that causes the deseas.
Experts say it will take many months to know if this vaccine ,or others also in research ,will work.
The first person to get the jab on monday was 43-years -old mother -of-two from seattle.
« This is an amazing opportunity for me do something , » Jennifer Haller told AP.
Scientists around the world are fast tracking research .
And this first human trial,funded by the National of health ,sidespeds a check that would normally be conducted making sure the vaccine can trigger an immune response in animal.
But the biotechnology company behind the work,Moderna Therapeutics, says the vaccine has been made using a tried and tested process.
Dr John Tregoning ,an expert in infectious diseases at Imperial College London ,UK, said : »This vaccine uses pre-existing technology ».
« It’s been made to a very high standard using things that we know are safe to use in people and those taking part in the trial will be very closely monitored.
« Yes ,this is very fast-but it is a race against the virus ,not against each other as scientists,and it’s being done for the benefit of humanity.
Typical vaccine for virus ,such as measles, are made from a weekend or killed virus.
but even thes initial safety tests go well ,it could still take up 18 months for any potential vaccine to become available for the public.
