Mandy Moore Leads Celebrity “Mom Squad” to Protect Babies from RSV

Actress Mandy Moore opened up about her sons’ dual RSV diagnoses and joined a Sanofi-backed mom collective to promote infant immunization.

In an exclusive interview with PEOPLE, Mandy Moore revealed that both her sons were diagnosed with respiratory syncytial virus (RSV) simultaneously in 2023, a scare that prompted her to partner with Sanofi and fellow celebrity mothers to encourage RSV protection for newborns.

Moore, known for her role on This Is Us, described the overwhelming helplessness she felt when sons August “Gus” Harrison and Oscar “Ozzie” Bennett fell ill, emphasizing the importance of proactive measures for her youngest child to avoid a repeat ordeal.

A Second Chance at Protection

After enduring the 2023 RSV scare without hospitalizations, Moore and her husband, musician Taylor Goldsmith, consulted pediatrician Dr. Danny Bruckner to immunize their daughter Louise “Lou” Everett with Beyfortus-the first long-acting monoclonal antibody approved to prevent severe RSV in infants. Lou received her dose on October 1, ensuring coverage through her first RSV season.

Joining Forces with Sanofi’s Mom Squad

On September 10, Sanofi announced that Moore has joined chef Gaby Dalkin, journalist Elaine Welteroth, gymnast Shawn Johnson East and astronaut Katya Echazarreta in a “Mom Squad” campaign. The group shares personal RSV experiences and advocates for Beyfortus as the #1 doctor-prescribed choice to protect babies entering RSV season.

Real-World Impact and Expert Endorsement

Dr. Bruckner notes that before Beyfortus’s approval, five to ten infants per winter required hospitalization for RSV; since its introduction, he reports zero hospitalizations in his practice. Clinical and real-world data involving over 400,000 babies confirm Beyfortus’s safety and effectiveness, reinforcing its recommendation for all infants regardless of birth timing or health status.

Why RSV Protection Matters

RSV remains the leading cause of hospitalization for children under one, with an estimated 590,000 cases annually requiring medical care in the U.S. Moore’s advocacy underscores the critical role of early immunization in preventing severe RSV lung infections and easing parental anxiety.
