It works! Moderna vaccine found to stop coronavirus in humans
A coronavirus vaccine trial based in the US will now be expanded to hundreds of people after it worked in eight patients.
One of the first COVID-19 vaccine to be tested in humans was able to build an immunity against the virus, according to Moderna, its US based manufacturer.
Eight healthy volunteers were given two doses of the vaccine in March.
The vaccine was successfully able to produce virus-fighting antibodies that were similar or greater than those found in patients who recovered.
It also prevented the virus from spreading.
According to Moderna, it was speeding up its testing by trialling it on 600 people, after the US Food and Drug Administration approved its application to do so earlier this month.
A third phase in July is set to involve thousands of healthy people.
“The imminent Phase 2 study start is a crucial step forward,” Stéphane Bancel, Moderna’s chief executive, said in a statement earlier this month.
Dr Tal Zaks, Moderna’s chief medical officer said depending on the results of the trial, the vaccine could become available by the end of the year or early 2021.
The technology being used by Moderna involves a segment of genetic material from the virus called messenger RNA, or mRNA.
They tested the vaccination on mice and found that it prevents the virus from replicating in the lungs.
Humans were also used in the trial, being tested with low, medium and high doses of the vaccine.
The highest caused fever, muscle aches and headaches, but the symptoms went away in a day.
