Moderna said Wednesday that preliminary data show that its bivalent COVID-19 vaccine booster gives a "superior antibody" response against the Omicron variant.

Driving the news: The bivalent booster candidate generated an eight-fold increase in immunization against Omicron, Moderna said.

  • The bivalent booster, called mRNA-1273.214, "was generally well-tolerated," with side effects comparable to the current booster dose, per Moderna.
  • The booster contains the original vaccine with an updated version that specifically targets the Omicron variant.

What they're saying: "Looking at these data alongside the durability we saw with our first bivalent booster candidate ... we anticipate more durable protection against variants of concern with mRNA-1273.214, making it our lead candidate for a fall 2022 booster," said Moderna CEO Stéphane Bancel.

  • "We are submitting our preliminary data and analysis to regulators with the hope that the Omicron-containing bivalent booster will be available in the late summer," Bancel added.

Catch up quick: Moderna announced in April its plans to offer the bivalent booster in the fall.

  • The company said the bivalent vaccine provided protection against the Delta and Omicron variants even though they were not specifically targeted.
