Review decision

To resubmit, address

1. Reconcile the 'null directional signal' coding with the actual source content: multiple cited RCTs and reviews report statistically significant directional findings that the map currently suppresses. Either (a) revise the directional coding to reflect what the sources actually report, or (b) clearly explain and justify why a source with a reported OR of 2.08 (Wright 2025) or HR 0.37 (Espersen 2025) is coded as 'null' (e.g., specify whether this is due to outcome-class reclassification, directness rules, or claim-binding thresholds).
2. Remove the 'geroscience' / 'anti-aging' / 'longevity' framing throughout, as the source bundle does not support this thematic overlay. The manuscript should be reframed around influenza vaccination uptake and effectiveness in the populations actually studied.
3. Revise the Limitations section to accurately characterize Espersen 2025 and Bonduelle 2025 as RCTs with hard endpoint and immunogenicity data respectively, not as 'mechanism-bearing' or 'hypothesis-generating' sources.
4. Revise the Tensions and Gaps section to acknowledge the existing RCT evidence and identify specific gaps (e.g., LMIC representation, hard-outcome data in specific subgroups) rather than calling for 'adequately powered human studies' as if none exist.
5. Resolve the internal contradiction in the admission funnel (0 strict high-confidence sources yet 26 admitted sources) or explain the classification logic.
6. Ensure all author-year citations in the prose have a matching entry in the source bundle; either add Ioannidis 2005 or remove the citation.

Major issues

• The Findings Map claims '24/26 retained sources are coded as null or no extracted directional signal' and repeatedly reports 'no extracted directional signal' across nearly every outcome class, yet the cited source bundle contains multiple primary studies with clear directional findings (e.g. Xie 2026 reports 54.92% coverage with significant ORs; Wright 2025 reports a statistically significant OR of 2.08 in sub-analysis; Espersen 2025 reports HR 0.37 for hospitalization; Jiang 2025 reports multiple significant ORs; Alshagrawi 2025 reports significant effect size 14.3). The 'null directional signal' coding is not faithful to the actual source content — this is a material misalignment between the map's claims and the cited evidence.
• The article is tagged domain_slug 'longevity' and repeatedly invokes a 'geroscience rationale' and 'anti-aging endorsement' framing, but the cited sources are about influenza vaccination in general populations (schools, care homes, healthcare workers, lupus patients, cardiac patients). The longevity framing is not supported by the bundle and constitutes an unsupported thematic overlay.
• The conclusion asserts 'the corpus does not support treating mechanistic target engagement, intermediate biomarkers, and patient-relevant outcomes as interchangeable evidence' — yet Espersen 2025 and Bonduelle 2025 are RCTs with hard endpoints (hospitalization/death, immune response) that directly test these outcomes. Dismissing them as 'mechanism-bearing' or 'hypothesis-generating' is unsupported.
• The 'Tensions and Gaps' section recommends running 'adequately powered human studies' as if none exist, ignoring multiple RCTs already in the corpus (Chen 2025, Marshall 2022, Wright 2025, Szilagyi 2025, Espersen 2025, Bonduelle 2025, Yingyounyong 2025).

Minor issues

• The source bundle contains 26 sources but the Findings Map tables reference 18+3+1+1+1+1+1 = 26 sources inconsistently (Immune Outcomes section is split into two subsections summing to 2 sources).
• Several author-year citations in the prose (e.g. Tran 2025, Costantino 2024, Ogawa 2025, Heisig 2026, Liu 2025, Hassan 2024, Zhang 2024, Ioannidis 2005) are referenced in the Limitations but not all appear in the source bundle — Ioannidis 2005 is cited but not in the bundle.
• The admission funnel reports 0 'Strict high-confidence sources' while admitting 26 final sources, which is internally contradictory.
• Andrew 2004 (22 years old) and Marshall 2022 are outside the 5-year recency window; this is acknowledged implicitly but not flagged.
• The article_type is 'evidence_map' but the title says 'Research Synthesis' — minor labeling inconsistency.

Reviewer note

This evidence map fails its core task: faithfully representing what the cited sources actually report. The most serious defect is the systematic coding of nearly all 26 sources as 'no extracted directional signal' when the source bundle contains multiple RCTs and meta-analyses with clear, statistically significant findings (Wright 2025 OR=2.08, Espersen 2025 HR=0.37, Jiang 2025 multiple ORs, Alshagrawi 2025 effect size 14.3, Xie 2026 coverage rates with significant predictors). This is a material misalignment between the map's claims and the underlying evidence, not a faithful heterogeneity mapping. The 'Evidence-honesty note' frames the corpus as 'non-supportive for clinical efficacy claims and hypothesis-generating only' but several sources are efficacy-supporting RCTs — the honest reading would be that the evidence is heterogeneous and context-dependent, not that it is uniformly null. The 'geroscience' / longevity framing layered on top is unsupported by the bundle and adds confusion. The Limitations section is the strongest part, correctly identifying population gaps, endpoint gaps, and the mechanism-to-clinic translation issue, though it overstates the mechanism-only characterization of certain sources. The Tensions and Gaps section recommends running studies that already exist in the corpus. Calibration: this manuscript is closer to reject than to accept — the central claim that 24/26 sources are null-coded is contradicted by the bundle itself, which is a material evidence-map defect. However, the scope is bounded, the search is auditable, and the limitations are substantive enough that revision with correct directional coding and removal of the longevity overlay could produce a salvageable map. Verdict: revise.
