Pipeline Vaccines

Methodology inspired by publicly taught vaccine development frameworks; all text is an original paraphrase.

Defaults

Preflight

Run canonical pre-flight per contracts/preflight.md. Include the X-Agentii-Trace header on every tool call per contracts/x-agentii-trace-header.md — carry the _run_id from your first tool result and name yourself (and your parent, if you were spawned). Confirm ticker resolution via search_companies before asset queries.

Triggers

• "Analyze [ticker]'s vaccine pipeline."
• "What seroconversion or immunogenicity studies support [vaccine]?"
• "Where are [ticker]'s vaccines in the efficacy ladder?"
• "Which lot-consistency trials are pending for [ticker]?"
• "What age-cohort bridging studies does [ticker] have planned?"
• "Does [ticker]'s vaccine have an ACIP path?"
• "Risk-adjust [ticker]'s vaccine pipeline."
• "What is the next catalyst for each of [ticker]'s vaccine assets?"
• "How do healthy-population efficacy designs change the evidence bar?"
• "Map [ticker]'s vaccines by antigen, cohort, and phase."
• "Which vaccine assets could reach a BLA in the next two years?"
• "What does [ticker]'s pipeline say about its seasonal strategy?"

Production Grounding

• Vaccine evidence ladder: immunogenicity/seroconversion studies (correlates, not efficacy) → efficacy trials in healthy populations (large N, safety-first) → lot-consistency trials (immunogenicity equivalence across three manufacturing lots — a licensure gate) → age-cohort bridging for pediatric and elderly label expansion.
• Healthy-population design: the efficacy bar is safety-first; endpoints prevent infection or disease; power comes from large N, and placebo arms shrink post-licensure (non-inferiority and bridging designs follow).
• Lot consistency is a regulatory milestone, not a formality: without it, licensure stalls regardless of efficacy data.
• The ACIP gate is part of pipeline value: a Phase III vaccine without a plausible ACIP path carries an unmodeled commercial step.
• Booster cycles and variant updates re-open the market; cohort bridging extends the label beyond the pivotal population.
• Grounding detail lives in references/knowledge-frameworks.md.

Data Source Priority

1. get_company_drugs / search_universe_drugs — vaccine asset inventory.
2. search_clinical_trials / get_clinical_trial — study design type, cohorts, status-diff, enrollment.
3. search_acip_events / get_acip_event — the gate path per vaccine; search_fda_approvals for BLA history.
4. Knowledge layer: search_knowledge_entries for framework grounding.

Methodology

Retrieval Scope

structured_only

Retrieval Strategy

1. Pull vaccine assets (get_company_drugs), cross-check the universe (search_universe_drugs).
2. Enrich per asset with trial records (search_clinical_trials) — design type, cohorts, status.
3. Map the ACIP path per asset (search_acip_events / get_acip_event).
4. Layer BLA and approval history (search_fda_approvals).
5. Size each asset (peak x POS); ground in knowledge entries.

Temporal Scope

See frontmatter temporal_scope block. Seasonal and bridging cycles span years; history may reach back 8-12 quarters.

Tool Allowlist

See frontmatter allowed_tools.

Protocol

1. Asset enumeration
2. Evidence-ladder mapping (immunogenicity → efficacy → lot consistency → bridging)
3. ACIP-path assessment
4. Cohort and booster overlay
5. Risk-adjusted synthesis

Modes

• Phase scan (default): all vaccine assets by stage with next catalyst and ACIP path.
• Cohort bridge: age-cohort expansions, booster cycles, and label breadth.
• Competitor map: antigen and indication overlap with class-read.

Tool Fallbacks

Output File

{ticker}/{YYYY-MM-DD_HHMM}_pipeline-vaccines_{affix}.md

Output Structure

1. Executive Summary — pipeline stance in 2-3 sentences
2. Asset Table — stage, design type, cohorts, next catalyst, ACIP path
3. Evidence Ladder — immunogenicity vs efficacy vs lot-consistency status per asset
4. Cohort & Booster Map — bridging studies, label breadth, seasonal strategy
5. Risk-Adjusted Sizing — peak x POS with the two-gate path made explicit
6. Coverage Gaps — missing records, undisclosed design, degraded modes
