First Human Trial of Covid19 Vaccine Takes Off In The USA With Volunteers Taking The JAB

The first human trial of a vaccine to protect against pandemic coronavirus is starting in the US on Monday

A group of 45 healthy volunteers will have the jab, at the Kaiser Permanent research facility, in Seattle.

The vaccine cannot cause Covid-19 but contains a harmless genetic code copied from the virus that causes the disease.

Experts say it will still take many months to know if this vaccine, or others also in research, will work.

And this first human trial, funded by the National Institutes of Health, sidesteps a check that would normally be conducted – making sure the vaccine can trigger an immune response in animals.

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 vaccines for viruses, such as measles, are made from a weakened or killed virus.

Typical vaccines for viruses, such as measles, are made from a weakened or killed virus.

But the mRNA-1273 vaccine is not made from the virus that causes Covid-19.

Instead, it includes a short segment of genetic code copied from the virus that scientists have been able to make in a laboratory.

This will hopefully prime the body’s own immune system to fight off the real infection.

The volunteers will be given different doses of the experimental vaccine.

They will each be given two jabs in total, 28 days apart, into the upper arm muscle.

But even if these initial safety tests go well, it could still take up to 18 months for any potential vaccine to become available for the public.
