Experimental coronavirus vaccine generated virus antibodies in small, early stage study

Early data from Moderna Inc.'s COVID-19 vaccine, the first to be tested in the United States, showed that it produced protective antibodies in a small group of healthy volunteers, the company said Monday.
The data comes from eight people who took part in a 45-subject safety trial that kicked off in March. The Moderna vaccine is one of more than 100 under development intended to protect against the coronavirus that has infected more than 4.7 million people globally and killed over 315,000.
Moderna's mRNA vaccine uses genetic material from the virus in the form of nucleic acid. That tells the human body how to make proteins that mimic viral proteins, and this should provoke an immune response. Overall, the study showed the vaccine was safe, and all study participants produced antibodies against the virus.
An analysis of the response in the eight individuals showed that those who received a 100-microgram dose and a 25-microgram dose had levels of protective antibodies to fend off the virus that exceeded those found in the blood of people who recovered from COVID-19, the illness caused by the coronavirus.
