Moderna is urging the US Food and Drug Administration to authorize a half-size booster of its Covid-19 vaccine, according to a briefing document posted Tuesday, ahead of a key meeting of the agency's vaccine advisers.
The company is asking for authorization for a 50-microgram booster dose -- half the size of the 100-microgram doses used in the primary series of the two-dose vaccine. The company says halving the dose increases protection against the coronavirus while helping the worldwide Covid-19 vaccine supply.The FDA's Vaccines and Related Biological Products Advisory Committee is meeting this week to consider booster doses of the Moderna and Johnson & Johnson Covid-19 vaccines.
On Friday, the advisers are scheduled to discuss and vote on whether to recommend authorization of boosters for Johnson & Johnson's Covid-19 vaccine. Both vaccines are already authorized for use in people age 18 and older. VRBPAC members will also hear a presentation on Friday on"mix and match" booster doses.
