Why exhibit at AAAAI
The larger of the two major US allergy/immunology meetings (AAAAI vs ACAAI), with 6,000+ attendees and 150+ exhibitors. Strong KOL presence for biologics companies, immunotherapy device manufacturers, and allergy diagnostic firms. Philadelphia 2026 location is accessible from major East Coast pharma/biotech hubs.
Why exhibit at ACAAI
The more practice-oriented of the two A/I meetings, attracting community and private-practice allergists who make independent purchasing decisions for their offices. If you sell allergy testing devices, immunotherapy delivery systems, or practice management software, ACAAI attendees are more likely to be direct buyers than the academic audience at AAAAI.
Why skip AAAAI
Allergy/immunology is a relatively small specialty -- if your device serves broader pulmonary or ENT applications, consider ATS or AAO-HNS instead. Both AAAAI and ACAAI serve similar audiences, so exhibiting at both may be redundant unless your product requires both academic (AAAAI) and community practice (ACAAI) channels.
Why skip ACAAI
Smaller audience (~3,000 vs AAAAI's 6,000) and lower KOL density. If you need clinical trial partnerships or academic endorsements, AAAAI is the better venue. Exhibiting at both AAAAI and ACAAI in the same year may be redundant for companies with limited trade show budgets.
