Pfizer Inc. (PREVNAR 20®)
(https://prevnar.com) 📸 Data Snapshot: June 19, 2026Pull the main entities out of the H1, then check whether they actually recur through the body. A page that announces one thing and then talks about another drifts. Headings with no real sentences underneath read as pseudo-substance.
There is no detectable semantic drift between the primary signal and sub-page indicators. The homepage promise of protection for adults and babies is consistently supported by the descriptions of pneumococcal pneumonia and invasive pneumococcal disease across the card identifiers. The intent remains strictly medical and educational without shifting into unrelated commercial claims.
Semantic Coherence is read from the heading hierarchy first: what each page announces in its H1 and headings, then whether the body actually delivers on it. Below is the structure the engine mapped, followed by the clean text to check for drift between promise and reality.
