Moderna Inc MRNA.O said on Monday its experimental vaccine was 94.5% effective in preventing COVID-19 based on interim data from a late-stage clinical trial, becoming the second U.S. company in a week to report results that far exceed expectations.
Together with Pfizer Inc’s PFE.N vaccine, also shown to be more than 90% effective, and pending more safety data and regulatory review, the United States could have two vaccines authorized for emergency use in December with as many as 60 million doses of vaccine available by the year’s end.

Next year, the U.S. government could have access to more than 1 billion doses just from the two vaccine makers, more than needed for the country’s 330 million residents.
The vaccines, both built using new technology known as messenger RNA or mRNA, represent powerful new tools to fight a pandemic that has infected 54 million people worldwide and killed 1.3 million. Of those, only five infections occurred in those who received the vaccine, which is administered in two shots 28 days apart.
The data from Moderna’s 30,000 participant-strong trial also showed the vaccine prevented cases of severe COVID-19, a question that still remains with the Pfizer vaccine.
Moderna, part of the U.S. government’s Operation Warp Speed program, expects to produce around 20 million doses of the vaccine for the United States this year, millions of which the company has already made, and is ready to ship if it receives FDA authorization.
Moderna has received nearly $1 billion in research and development funding from the U.S. government and has a $1.5 billion deal for 100 million doses.
The U.S. government has said COVID-19 vaccines will be provided free to Americans, whether they have health insurance, are uninsured or are covered by government health programs such as Medicare.
Russia licensed its “Sputnik-V” COVID-19 vaccine for domestic use in August before it released data from large-scale trials.
It said on Nov. 11 that its vaccine was 92% effective based on 20 infections in its large trial.
