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. The FDA previously authorized boosters of Pfizer's Covid-19 vaccine for some adults.
