Infant and High-Risk Children RSV Prevention Program Update for the 2025-2026 Season

Alert Date
Location
Windsor-Essex County

As spring approaches, the Ontario Ministry of Health has issued updated guidance regarding the Respiratory Syncytial Virus (RSV) prevention program for infants and high-risk children.

Infant and High-Risk Children RSV Prevention Program

  • In previous program materials, RSV season was noted to generally conclude at the end of March.
  • Based on current epidemiological data, including percent positivity and hospitalizations, community transmission of RSV is ongoing.
  • Activity remains variable across the province and overall continues to remain high, particularly among infants and children.
  • As a result, the RSV prevention program for infants and high-risk children will be extended into April 2026.

Program Guidance

  • Healthcare providers should continue to recommend and administer RSV immunizations to  eligible infants and children until the Ministry circulates further communication.
  • The decision to administer maternal vaccination should take into consideration the timing of administration during pregnancy (i.e., between 32-36 weeks gestation) and the upcoming timing for the end of the season.

  • Guidance for the 2026/27 program will be provided leading up to the fall and will include recommendations for those infants and children who receive RSV protection late this season. 

Order Process

Orders for RSV products should continue to be placed through WECHU’s current vaccine ordering process. https://www.wechu.org/professionals/health-care-providers/vaccine-providers
