US biotech firm Moderna said Tuesday it would enter the final stage of human trials for its COVID-19 vaccine on July 27, to test how well it protects people in the real world.


The announcement came as the results from an earlier trial intended to prove the vaccine was safe and triggered antibody production were published.


The upcoming Phase 3 trial will recruit 30,000 participants in the US, with half to receive the vaccine at 100 microgram dose levels, and the other half to receive a placebo.


Researchers will then track them over two years to determine whether they are protected against infection by the virus. Or, if they do get infected, whether the vaccine prevents symptoms from developing.


If they do get symptoms, the vaccine can still be considered a success if it stops severe cases of COVID-19.


The study should run until October 27, 2022, but preliminary results should be available long before.


The announcement came shortly after the New England Journal of Medicine published results from the first stage of Moderna's vaccine trial, which showed the first 45 participants all developed antibodies to the virus.


Moderna is considered to be in a leading position in the global race to find a vaccine against the coronavirus, which has infected more than 13.2 million people and killed 570,000.
