Assessment

Supported

Score: 0.9561 under ledger-default@0.3.0 at snapshot 27745

3 of 4 review checks done · 1 counted · 2 by the author only

2 independent evidence lineages · review checks 1 of 4 · stability HIGH

Main unresolved issue: 4 counted evidence items have no independence review; repeats of one origin may be counted as several coverage:72b71502-daf2-8b24-97c9-6e4d7750602a

Not yet independently audited.Evidence reviewed so far supports this claim, but only 1 of 4 review checks has been done.A quoted passage from news.mit.edu was not found on the page when Galedra fetched it.

Why?

Strongest counted support: MIT reports one-year room-temperature or two-month 98°F storage stability and equivalent immune responses in mice after storage. weight 2.000000 evidence

Suppressed as dependent: The excerpt directly states that mice receiving the heat-stored particles showed equivalent immune responses to mice receiving LNPs similar to the original Moderna formulation.

Review gaps: qualifiers reviewed, opposing search done, independence reviewed

What would most change this: One independent, direct measurement that contradicts this claim would move it from Supported to Leans supported.

How the number was reached

Each counted link is weighed by multiplying the factors the model declares; a factor it does not declare is not shown. Every factor name below links to what that number means.

prior 0.50 → log-odds 0.000000 + 3.080000 (the counted weights) = 3.080000 → probability 0.9561

Under neighbouring settings of the same model: 0.8962 to 0.9821, a spread of 0.0859.

Half-even rounding, six places for weights and four for the probability. The same inputs under the same model reproduce this exactly; that is what the trace hash above is for. How a score is worked out explains every factor, why it is there, and what the model sets it to.

Evidence for

MIT reports one-year room-temperature or two-month 98°F storage stability and equivalent immune responses in mice after storage.

From New formulation helps RNA vaccines withstand high temperatures Read 2026-09-28 Relevance DIRECT Steps 0 Counted

The passage directly compares immune responses in mice.
The peer-reviewed study reports non-inferior antigen-specific immune responses in rodents and non-human primates from thermostable formulations versus freshly prepared soluble vaccines.

From Accelerated discovery of thermostable mRNA–lipid nanoparticle vaccines using data-efficient AI Read 2026-09-28 Relevance STRONG Steps 0 Counted

Peer-reviewed primary evidence supports the comparative immune-response result, while covering rodents and non-human primates rather than mice alone.
The excerpt directly states that mice receiving the heat-stored particles showed equivalent immune responses to mice receiving LNPs similar to the original Moderna formulation.

The passage directly matches the comparative claim and is limited to mice and the stated formulations.

Evidence against

None.

Qualifications

The equivalence result is limited to mice after storage at room temperature for one year or 98°F for two months.

The exact storage conditions materially bound the reported immune-response equivalence; the claim omits those durations.

Inferences

Concluded from

None.

Used as a premise in

None.

An inference is interpretation, not evidence: it never changes the assessment of its conclusion. Each premise is a claim with its own evidence.

Threads

None. Threads are for disagreements about how a determination was made — a statement whose figures are not in the passage it rests on, two sources that may share an origin. Something about the world belongs in the evidence above.

Claim edges

None. Edges are stored and displayed; v0.1 does not propagate probability across them.
