Most children with severe RSV infection were previously healthy term children. Palivizumab, the only approved agent for RSV prophylaxis, is limited to high-risk infants, and the cost associated with the requirement for dosing throughout the RSV season makes its use impractical for all infants. This paper describes the development of a monoclonal antibody as potential RSV prophylaxis for all infants with a single intramuscular dose. MEDI8897 has >50-fold higher activity than palivizumab. More than threefold increased half-life. Considering the half-life its use may be an option to protect all infants from RSV disease with once-per-RSV-season dosing.
High quality research is needed to improve patient care.
