Moderna has announced Friday that it has entered phase two of vaccine clinical trials for COVID-19.
The mid-stage of the vaccine intends to enroll 6-hundred patients, and the first group of participants have already been dosed with the vaccine candidate.
Earlier this month, Moderna released positive results for the phase one study, showing that participants have developed antibodies against the virus.
There are currently around 10 vaccines for COVID-19 that are under clinical tests on humans.
Experts predict that it could take from 12 to 18 months for a safe and effective vaccine to be developed.
