As countries tightened restrictions and markets globally sold off over the fast spread of Omicron, some welcomed news on the effectiveness of booster shots. Moderna said Monday lab tests showed its COVID-19 booster shot appeared to be protective against the Omicron variant.
Moderna’s chief medical officer said it’s so effective that it’ll – in his words – “protect people through the coming holiday period.”
The company said a 50 microgram booster dose increased neutralizing antibodies 37-fold against the Omicron variant.
The data has not yet been peer reviewed. But investors cheered the news, sending Moderna shares sharply higher in early trading Monday.
U.S. regulators authorized Moderna’s 50 microgram booster in October.
Earlier this month, Pfizer and BioNTech said a three-shot course of their vaccine also neutralized Omicron in a lab test.
