BBC News said that the first clinical trials of a Coronavirus vaccine were applied on Monday, March 16, 2020.

The vaccine will be tested in a group of 45 healthy volunteers at Kaiser Permanente Research Center in Seattle, Washington.
According to a news bulletin from the center, the first four volunteers received a dose for a clinical trial supported by President Donald Trump’s Government.

The vaccine can’t infect with Covid-19, but it contains a harmless genetic code copied from the virus that causes the disease.

18 months

According to the experts, it will take several months, maybe up to 18, to know if this vaccine, or others under development, work.

In the case of the first trials on humans, funded by the National Institute of Health (NIH), they are overstepping a previous stage that is normally used in this type of studies: make sure that the vaccine is capable of provoking an immune response in animals.

However, the biotech company responsible for the investigation, Moderna Therapeutics, says that the vaccine was created using a process of proved reliability.
“This vaccine uses a preexistent technology. It was created with a high standard, using things that we know that are safe for people, and those participating in the trial will be subjected to a very rigorous study”, said doctor John Tregoning, a infectious diseases expert from London’s Imperial College.

“Yes, this is very fast, but it’s a race against the virus, not against other scientists, and it’ being done for the sake of Humankind”, Tregoning added.
Usually, vaccines against viruses, like measles, are done with weakened or dead samples of the virus.

Two shots

But the mRNA-1273 vaccine was not created with the virus that causes Covid-19.

Instead, it includes a small segment of a genetic code copied from the virus that scientists have been able to create in the lab.

Hopefully, this will prepare the body immune system to fight the real infection.
The volunteers will receive different doses of the experimental vaccine. Each one of them will receive a shot in the arm on two occasions, with a 28 days interval between doses.

But even if those initial tests go well, it might take up until 18 months for a possible vaccine to be available to the general public.
