How is Beyfortus administered?

Beyfortus is administered as a single dose for prophylaxis against respiratory syncytial virus (RSV) in high-risk infants and young children. This dosing strategy is crucial because it allows for immediate protection without the need for a prolonged treatment regimen. The single administration simplifies the logistics of treatment for both healthcare providers and families, ensuring that infants receive the necessary protective measures efficiently and effectively.

The other options suggest various schedules that do not align with the recommended usage of Beyfortus. For instance, administering the medication weekly or daily does not correspond with its safety profile or the established guidelines for its use in preventing RSV. Monthly treatments or extended timeframes can potentially lead to unnecessary complications or increased healthcare burdens without providing additional benefits in this context. Thus, a one-time dose remains the most effective and practical approach for prophylaxis with Beyfortus.
