Moderna said today its COVID-19 vaccine is proving to be highly effective in a major trial, a second dash of hope in the global race for a shot to tame a resurgent virus that is now killing more than 8,000 people a day worldwide.

The company said its vaccine appears to be 94.5% effective, according to preliminary data from Moderna’s ongoing study. A week ago, competitor Pfizer Inc. announced its own COVID-19 vaccine appeared similarly effective — news that puts both companies on track to seek permission within weeks for emergency use in the U.S.

The results are “truly striking,” said Dr. Anthony Fauci, the U.S. government's top infectious diseases expert. Earlier this year, Fauci said he would be happy with a COVID-19 vaccine that was 60% effective.

A vaccine can’t come fast enough, as virus cases topped 11 million in the U.S. over the weekend — 1 million of them recorded in just the past week — and governors and mayors are ratcheting up restrictions ahead of Thanksgiving. The pandemic has killed more than 1.3 million people worldwide, over 245,000 of them in the U.S.
