Moderna vaccine success gives world more hope
Vaccine candidate is 95% effective
WASHINGTON: Moderna Inc’s experimental vaccine was 94.5% effective in preventing COVID-19 based on interim data from a late-stage trial, the company said on Monday, becoming the second U.S. drugmaker to report results that far exceed expectations.
Together with Pfizer Inc’s vaccine, which is also 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 this year.
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 developed with new technology known as messenger RNA (mRNA), represent powerful tools to fight a pandemic that has infected 54 million people worldwide and killed 1.3 million. The news also comes at a time when COVID-19 cases are soaring, hitting new records in the United States and pushing some European countries back into lockdowns.
“We are going to have a vaccine that can stop COVID-19,” Moderna President Stephen Hoge said in a telephone interview.
Moderna’s interim analysis was based on 95 infections among trial participants who received either a placebo or the vaccine. Of those, only five infections occurred in those who received the vaccine, which is administered in two shots 28 days apart.
“Having more than one source of an effective vaccine will increase the global supply and, with luck, help us all to get back to something like normal sometime in 2021,” said Eleanor Riley, professor of immunology and infectious disease at the University of Edinburgh.
Moderna expects to have enough safety data required for U.S. authorization in the next week or so and the company expects to file for emergency use authorization (EUA) in the coming weeks. - Reuters
