The RSV season, when outbreaks of respiratory syncytial virus tend to occur, is from the fall to the end of spring [1][3][4][6]. In the United States, RSV typically circulates in the fall and winter months [2][5]. The season usually begins in late fall and lasts until spring in Canada [3]. Infants, especially premature infants or babies who are 6 months or younger, are at increased risk of severe or life-threatening RSV infections [1]. It is recommended to get the RSV vaccine during September through January in most parts of the United States [2]. Healthcare professionals may consider monthly injections during the RSV season to help prevent infection in high-risk infants [9].
