Mini Case Study No. 4 — Pfizer: Trust at Scale, Misinformation at Speed
Context:
Pfizer ranks #1 in the AIVO 100™ Healthcare & Pharma cut with a PSOS of 87. Its visibility in AI assistants reflects leadership in vaccines, but also the persistence of entrenched narratives. That dominance creates exposure: misinformation risk, regional fragility, and reputational overlays.
Key Insights
- High Recall, High Risk
Pfizer is the most recalled vaccine brand in ChatGPT and Gemini prompts, but 12% of recall contains outdated or misleading vaccine information — the highest misinformation rate in the Top 10. - Decay in Context
Pfizer’s recall decays ~15% in 90 days when not reinforced. By comparison, Moderna falls -22% and J&J under 8%. Pfizer is losing ground faster than J&J but slower than Moderna, underscoring vulnerability despite scale. - Regional and Reputational Gaps
Recall is strong in North America and Europe, but ~20% weaker in Asia. Pricing controversies and political narratives also surface in prompts, showing how assistants embed both trust and skepticism.
Governance Takeaway
For healthcare and pharma boards, Pfizer illustrates the dual mandate of AI visibility:
- Sustain presence against structural decay.
- Audit misinformation overlays across assistants as rigorously as pharmacovigilance data.
- Manage reputation proactively: litigation, pricing, and political narratives are encoded in recall and must be monitored continuously.
In AI search, dominance does not mean control. Trust must be defended at the same cadence as safety and compliance.
