What VaxBrief Is

VaxBrief is an independent daily narrative surveillance brief monitoring vaccine-related discourse across five regions: the United States, Canada, the United Kingdom, Australia, and New Zealand.

Its purpose is to provide structured, neutral documentation of narratives that may be relevant to public health communicators, policy staff, clinicians, and researchers — without advocating for specific positions or outcomes.

VaxBrief is designed for readers who need situational awareness, not persuasion.


Publication Format

VaxBrief publishes daily. Each brief is structured for three reading depths:

  • Skim (90 seconds): The Lede and Executive Summary identify the day’s dominant signal and highest-risk items.
  • Read (4–5 minutes): Key Narratives, Regulator/Narrative Gap, and Risk & Watchpoints provide detail on active narratives, institutional context, and risk classification.
  • Analyse (8–12 minutes): Emerging Signals, Legacy Context, Actionable Gaps, and Narrative Background & Historical Context provide historical trajectory, persistence mechanisms, and communication science recommendations.

The Narrative Background & Historical Context section (Section 9) documents the evolution of persistent narratives over time. It functions as the brief’s institutional memory and replaces the need for a separate weekly product.


Data Sources

Only publicly accessible materials are used. These include:

  • Government and regulatory agency publications (TGA, ATAGI, Medsafe, Pharmac, MHRA, EMA, CDC, HHS, Health Canada, WHO)
  • Peer-reviewed journals and pre-print servers
  • Mainstream and specialist news media
  • Public blogs, open social media, and Substack publications
  • Fact-checking and public health counter-narrative outlets

Closed groups, private communications, paywalled analytics, and proprietary databases are not accessed or inferred. No personal data is collected.


How the Brief Is Produced

VaxBrief uses a structured three-stage pipeline:

Stage 1 — Daily Scan: An AI-assisted scanning tool monitors the last 24 hours across monitored regions, identifying active narratives, emerging threats, regulatory transitions, and silence triggers — instances where the absence of expected agency communication is itself generating discourse.

Stage 2 — Legacy & Persistence Assessment: A second AI-assisted process assesses the historical weight of each narrative — distinguishing newly active claims from resurgent historical frames and evergreen persistent narratives. This layer produces the Legacy Depth Record that populates Section 9 of each brief.

Stage 3 — Editorial Synthesis: A structured editorial layer synthesises both inputs into the published brief, applying consistent classification, risk assessment, and communication science tagging. All claims are traceable to the provided inputs; nothing is added editorially.

AI tools are used only to assist with discovery, classification, and structured synthesis of publicly available content. They do not generate evidence, infer causality, or substitute for editorial judgment.


Narrative Classification

Narratives are classified using predefined categories to distinguish signal types:

  • Active Narrative: Currently circulating with documented momentum
  • Legacy Driver: A historically persistent frame that is structurally shaping how current claims are being made or received
  • Evergreen Narrative: A low-velocity, high-consistency narrative present continuously across monitored regions
  • Regulatory Memory: A narrative anchored in a past regulatory decision or institutional statement

Risk classifications (High / Medium / Low) are assigned using a documented two-factor rule based on population impact, policy leverage, velocity, platform targeting, and other structural factors.


What VaxBrief Is Not

VaxBrief is a monitoring and synthesis brief focused on what is being said, where, and with what apparent momentum. It is grounded in publicly observable information.

VaxBrief is not:

  • A determination of scientific validity or clinical guidance
  • A fact-checking service
  • A real-time news feed
  • A policy recommendation platform

Narrative presence does not imply prevalence, causality, or impact. Inclusion of a claim does not imply endorsement or accuracy. Absence of a narrative from a given brief does not indicate resolution.


Evidence Anchoring

Where narratives reference evidence, Evidence Anchors are recorded as cited in source material. These may include official documents, journal articles, or media reports. All anchors are flagged as accessibility unverified — VaxBrief does not guarantee live link status at time of publication.

Evidence Anchors are presented for traceability and transparency, not endorsement.


Limits and Uncertainty

VaxBrief operates in environments where information may be incomplete, claims may evolve rapidly, and visibility does not correlate with evidentiary strength. VaxBrief does not attempt to adjudicate truth or forecast outcomes. Its role is to support awareness and preparedness, not decision-making.


Governance and Independence

VaxBrief is independently produced. It is not commissioned by governments, political actors, advocacy groups, or commercial entities with an interest in vaccine policy or products.

Editorial decisions are guided by consistency, proportionality, and restraint. VaxBrief is produced by a vaccinologist and science communicator with experience working across academic, policy, and public-facing science environments.
