What a claim record is How to read this page

One statement, bounded on purpose

The headline is a single claim that a named source supports. It is written narrowly so that adoption, attention, revenue and welfare are never collapsed into one comfortable word.

The three sections below the fold

What this does not establish is the boundary of the evidence. Counterevidence & uncertainty is what argues the other way. What would change the reading is the observation that would move it. A record missing any of the three is incomplete, not merely brief.

Primary routes are checkable

Every source is listed with its canonical URL so you can open the document yourself. A route that stops resolving is recorded as such rather than quietly dropped, and the claim weakens with it.

MWITA-FT-2026-005 · Evidence A · P1

Anvisa registered the Butantan dengue vaccine in December 2025 for ages 12–59 after a five-year Brazilian phase 3 programme; regulatory approval and local production capability now precede national rollout evidence.

Counterevidence & uncertainty

Trial efficacy, age indication and supply do not establish real-world effectiveness across serotypes, outbreaks, geographies or programme coverage.

What would change the reading

Update with PNI incorporation, delivered doses, coverage, serotype-specific effectiveness, severe-disease outcomes and safety surveillance.
