There is already a coronavirus vaccine, and a woman in Seattle is the first person to trial it.

A new phase 1 clinical trial of a potential vaccine for the SARS-CoV2 coronavirus began on Monday in Seattle. According to Forbes, the vaccine, mRNA-1273, was developed by biotechnology company Moderna in combination with researchers from the National Institutes of Health (NIH). 

Jennifer Haller, 43, from Seattle who said; "I hope that we get to a working vaccine quickly and that we can save lives and people can go back to life as soon as possible," in an interview with TIME.

"We all feel so helpless. This is an amazing opportunity for me to do something," Haller continued. Haller is the mother of two teenagers and "they think it's cool" that she's taking part in the study.

Kaiser Permanente study leader Dr. Lisa Jackson administered the vaccine but remains cautious about any potential results.

"We don't know whether this vaccine will induce an immune response, or whether it will be safe. That's why we're doing a trial," Jackson stressed. "It's not at the stage where it would be possible or prudent to give it to the general population."

This is what TIME reports the vaccine will do.

"The body will become a mini-factory, producing some harmless spike protein. When the immune system spots the foreign protein, it will make antibodies to attack — and be primed to react quickly if the person later encounters the real virus. That's a much faster way of producing a vaccine than the traditional approach of growing virus in the lab and preparing shots from either killed or weakened versions of it."
