Title: Sanofi’s Infant RSV Shot, Beyfortus, Receives FDA Approval to Combat Respiratory Virus
Sanofi, a leading pharmaceutical company, has announced that it expects its infant respiratory syncytial virus (RSV) shot, Beyfortus, to be available in the U.S. market before the onset of the respiratory virus season this fall. The shot has recently received approval from the U.S. Food and Drug Administration (FDA) as a preventive measure against RSV infections in infants.
The collaborative effort between Sanofi and AstraZeneca has led to the successful development of Beyfortus, a monoclonal antibody that provides protection against RSV. The antibody is administered directly into the bloodstream, similar to how vaccines work to stimulate the immune system’s antibody production.
Sanofi is confident in its ability to meet the demands for the RSV shot, assuring that there will be no manufacturing or capacity challenges. However, the company is currently working towards incorporating Beyfortus into the U.S. childhood immunization schedule and hopes for its inclusion in the federal Vaccines for Children program. Sanofi faces some uncertainty due to the classification of Beyfortus as a drug rather than a vaccine.
To discuss the administration of Beyfortus, the Centers for Disease Control and Prevention’s (CDC) independent advisors are scheduled to convene on August 3. The panel, in collaboration with Sanofi, will determine the most effective protocols for administering the shot.
Preventing RSV is crucial as the virus is the leading cause of hospitalization among infants in the United States, and around 100 infant deaths are reported each year. The severity of last year’s RSV cases overwhelmed children’s hospitals, prompting calls for a public health emergency declaration by the Biden administration.
In clinical trials, Beyfortus has demonstrated remarkable effectiveness, with up to a 75% reduction in lower respiratory tract infections in infants that required medical attention. This makes Beyfortus the first shot approved in the U.S. to protect infants against RSV, irrespective of their health condition. Previously, the only available preventative option for preterm or medically vulnerable babies was a shot called palivizumab.
Sanofi’s development and approval of Beyfortus marks a significant milestone in combating RSV infections among infants. With hopes of swift integration into vaccination programs, parents can look forward to the increased protection of their little ones from this potentially severe respiratory virus.
