Abstract Submission Update

Important Update: Regular Abstract Submission Deadline 

AAI is aware of the many challenges impacting our members, the immunological enterprise, and the wider scientific community. Between grant freezes, funding terminations, delayed grant reviews, and government shutdowns, AAI’s community has never faced such uncertainty and disruption. 

AAI’s mission is to improve global health and well-being by advancing immunological science and supporting scientists through knowledge dissemination, community building, advocacy, and public outreach. To ensure everyone has access to opportunities for scientific collaboration and networking, AAI is extending the deadline for submitting Regular Abstracts until 6 PM ET on October 22, 2025. 

Submitting a Regular Abstract give you the opportunity to present your research at IMMUNOLOGY2026™. All abstracts undergo a rigorous evaluation process to ensure the quality, relevance, and the originality of the presentations to be given at IMMUNOLOGY2026™. Accepted abstracts will be presented as either a Major Symposium, Block or Poster presentation. Approximately 18-20% of all submissions receive an invitation to present a podium presentation. 

AAI will also be opening a second round of Regular Abstract submissions December 2 – 16, 2025. This will provide those impacted by the government shutdown, and those dealing with uncertainty around funding, with another opportunity to submit their research for presentation at IMMUNOLOGY2026™. 

There will also be a Late-Breaking Abstract submission period in early 2026. Late-breaking abstracts are eligible for poster presentation only.  

If you are a federally employed AAI member scientist affected by the government shutdown and unable to access your membership, please contact us at meetings@aai.org to find out how we can help get you access.
