The third injection of Moderna’s COVID-19 vaccine provides a “reassuring” level of protection against the omicron variant, the pharmaceutical company announced Monday as the newer strain continues to spread.
The booster injection, equivalent to half the dose of the first two, increased antibody levels against omicron 37-fold based on preliminary data, according to Moderna.
“The dramatic increase in omicron variant COVID-19 cases is concerning to all. However, these data showing that the currently authorized Moderna COVID-19 booster can increase neutralizing antibody levels 37 times higher than previous levels to reinforcement are reassuring,” Stéphane Bancel, CEO of Moderna, said in a statement.
Moderna is still working on a “specific reinforcement of omicron,” Bancel said. Clinical trials could start as early as 2022.
The company’s preliminary study examined 20 booster recipients 29 days after injection.
Moderna is also experimenting with a full-dose booster injection, which so far is “generally safe and well-tolerated” but has shown more frequent adverse reactions than half-dose.
