HIV pre-exposure prophylaxis (PrEP) and post-exposure prophylaxis (PEP) are safe and effective biomedical prevention strategies and are key to ending the HIV epidemic as a public health threat by 2030. On December 1, 2025, in commemoration of World AIDS Day, a working group of the CIHR Pan-Canadian Network for HIV/STBBI Clinical Trials Research (CTN+) published an update to Canadian clinical guidelines on PrEP/PEP in the Canadian Medical Association Journal. The guideline was developed by a diverse panel that conducted preliminary community consultations, performed systematic reviews of published literature, deliberated on the data using a rigorous evidence-to-decision framework, and ultimately formulated recommendations using the GRADE methodology. Key topics covered include who to prescribe PrEP and PEP to, which regimens to prescribe, and how to provide counseling, monitoring and follow-up. This session will review key takeaways from the guideline for clinicians, and may also be of interest to public health officials/community representatives.

Intended Audience:
Public health clinicians, Public Health professionals who work in sexual health, community health care workers, program staff involved in STBBI prevention initiatives, pharmacists, researchers working in STBBIs or HIV prevention.

By the end of this event, participants will be able to:

• Describe recent epidemiologic trends in first-time HIV diagnoses and uptake of HIV PrEP in Ontario.
• Describe the current Canadian guideline recommendations for identifying individuals who are appropriate candidates for HIV PrEP and PEP.
• Identify evidence‑based antiretroviral regimens for HIV PrEP and PEP in clinical practice.
• Identify and access accredited, self‑directed online educational resources to further support ongoing learning about PrEP and PEP.
