All 21 members of the FDA’s Antimicrobial Advisory Committee (AMDAC) who attended the meeting “agreed” when asked whether a comprehensive benefit-risk assessment of the drug nircevimab would be beneficial in preventing respiratory syncytial virus infection. and voted.

Mary Ann Jackson, dean of medicine at the University of Missouri, Kansas City, said she voted in favor because of the need for such a drug, and said she was convinced by a presentation made during the conference.
