Moderna Inc on Tuesday said the US Food and Drug Administration should authorize booster doses of its Covid-19 vaccine in fully vaccinated older adults and high-risk individuals.
The company said its data supports the public health benefit of a booster dose of its vaccine to restore immune response, while reducing the number of "breakthrough" infections in fully-vaccinated adults.
Moderna's comments were released in briefing documents ahead of a Thursday and Friday meeting of the FDA's outside expert advisers to discuss booster doses of Moderna and Johnson & Johnson's Covid-19 vaccines.
Rival Johnson & Johnson on Tuesday also cited data showing increased protection after a booster dose, which it said could be either administered as early as two months after the original dose of its vaccine.
