National Public Radio reported:
The results for both vaccines come from interim analyses of large clinical studies. In the Moderna study there were 30,000 volunteers. Half got two doses of the vaccine 28 days apart, half got two shots of a placebo on the same schedule.
Both the Moderna and Pfizer vaccines use the same technology to make their vaccines. It’s based on a molecule known as mRNA, or messenger RNA. That molecule contains genetic instructions for making proteins inside cells.
The federal Operation Warp Speed project to hasten development of COVID-19 vaccines awarded Moderna a $1.5 billion contract in August to ramp up manufacturing and deliver 100 million vaccine doses, enough for 50 million people. The government has an option to buy up to 400 million more doses.
Moderna said Monday that it expects to be able to ship about 20 million vaccine doses in the U.S. by the end of 2020. Next year, the company said it expects to be able to make 500 million to 1 billion doses worldwide.
Moderna reported that its coronavirus vaccine was 94.5% effective in clinical trials, the latest good news for Trump's Operation Warp Speed.
