The Department of Public Health and Human Services (DPHHS) announced on March 18 that health care providers in Montana should continue offering preventive immunizations against Respiratory Syncytial Virus (RSV) for infants and young children through April 30.
This recommendation follows guidance from the Centers for Disease Control and Prevention, as RSV activity has started later than usual this year and continues to rise both in Montana and nationally. The extension aims to protect infants from severe complications associated with the virus, which is a leading cause of infant hospitalization in the United States.
Typically, RSV immunizations are given between October and March. However, due to ongoing transmission, DPHHS determined an additional month is needed. “Montana’s RSV activity is still increasing,” DPHHS State Medical Officer Dr. Doug Harrington said. “Extending access to RSV preventive antibodies through April gives families and providers more time to get eligible infants covered during this heightened period of activity. We encourage parents to talk with their child’s provider as soon as possible.”
The department encourages providers to offer immunization through April 30 for infants younger than eight months who have not yet been immunized this season, ideally within their first week of life or during any health care visit. Children ages eight to nineteen months who are entering their second RSV season and are at increased risk for severe disease are also eligible.
DPHHS urges caregivers to consult with pediatricians about eligibility for protection against RSV. The department advances conditions for healthy living by empowering individuals through evidence-based programs across communities, according to the official website. It oversees facilities such as the Montana State Hospital and veterans’ homes for specialized care, according to the official website. DPHHS aims to enhance health, safety, well-being, and independence for Montanans through integrated programs and services, according to the official website.
The agency features direction from a Director’s Office and executive team focused on strategic oversight, according to the official website. It delivers supports statewide across Montana’s diverse regions, according to the official website. DPHHS builds healthier communities through partnerships with local, tribal, and community organizations, according to the official website.
