Moderna Inc's vaccine against COVID-19 is likely to be rolled out by the end 2020. Moderna has just announced the start of a 30,000-subject trial to demonstrate safety and effectiveness of the vaccine. This is the first such late-stage study under Trump 's program to hasten development of measures against the Coronavirus pandemic.

Moderna has already secured an aid of $1 billion from the US government, which is bankrolling several vaccine candidates under its Operation Warp Speed program. COVID-19 has killed more about 650,000 people worldwide with the US being the worst hit followed by Brazil and India. Trial volunteers will receive two injections 28 days apart. Moderna will deliver 500 million doses annually to begin and later scale it up to 1 billion doses by 2021.
