Modern announces positive results from Omicron vaccine
U.S. biotech company Moderna on Wednesday announced positive results from a new vaccine that targets both the original strain of Covid-19 and Omicron, and considers the vaccine a “top candidate” for a booster vaccine this fall.
The so-called “bivalent” vaccine was tested on 814 adults and found to produce 1.75 times more Omicron-specific neutralizing antibodies capable of preventing infection than Moderna’s original Spikevax vaccine.
All participants had previously received three doses of Spikevax, and then just over half received a fourth dose of a bivalent injection, while the rest received another dose of Spikevax. Antibody levels were checked one month later.
The group that received the new vaccine also received slightly better protection against the ancestral strain of Covid-19 compared to Spikevax, even though the original Covid has long since disappeared from circulation.
“We are thrilled,” Moderna CEO Stephane Bancel said in a statement, adding that he expects the vaccine to be the company’s top candidate for authorization as a booster this fall.
“We want to be ready for shipment as early as August,” he added in a telephone conversation with investors.
The results were widely acclaimed by experts, who agreed that the Moderna vaccine is currently the leader as a booster, although some voiced caution.
“We won’t know the clinical results until the end of this year,” Eric Topol, a physician and scientist at the Scripps Translational Research Institute, tweeted. The study only deals with antibody levels, which are thought to be a useful indicator of how a vaccine will work, but cannot provide accurate predictions.
Breakthrough infections have increased since Omicron became dominant at the end of 2021, and vaccine makers hope to restore efficacy to previous levels, even as first-generation vaccines continue to protect well against severe illness and death.
