Episode notes
Trials Need Post‑Licensure Surveillance
- Randomized controlled trials cannot reliably detect extremely rare adverse events because of limited size and follow-up.
- Robust post-licensure systems (VAERS, VSD, PRISM) are essential to detect and evaluate rare safety signals.
Use VAERS As A Signal, Not Proof
- Treat VAERS reports as early-warning signals that require follow-up with controlled data sources.
- Verify signals via VSD, PRISM and other controlled databases before asserting causality.
Childhood Schedule Misconceptions
- The current childhood schedule covers 16 diseases with about 50–54 doses up to age 18, not 92.
- Modern schedules expose children to far fewer antigenic components than older whole‑cell vaccines did.
