Which medication is given to high-risk preterm infants to prevent infection from RSV?

Explanation:
The main concept is preventing RSV illness in high‑risk preterm infants with a passive immunization approach. Palivizumab is a monoclonal antibody given by monthly injections during RSV season to provide immediate protection by binding the RSV F protein and neutralizing the virus, which reduces hospitalization risk. It is used specifically for prophylaxis, not as a vaccine that stimulates the infant’s own immune response. Ribavirin is an antiviral used to treat RSV infections in certain hospitalized infants, not for routine prevention. Interferon isn’t a standard RSV prophylaxis. Oseltamivir targets influenza, not RSV. Therefore, Palivizumab is the best choice for preventing RSV infection in these high‑risk infants.
