As the current respiratory syncytial virus (RSV) season ends, most infants are protected against this severe disease.
According to the U.S. CDC's MMWR ( 74(16);273–281) published on May 8, 2025, in the first RSV season with widespread availability of maternal vaccine and long-acting monoclonal antibody, RSV-associated hospitalization rates among infants were lower than in prepandemic seasons.
