A what‑if from the future

What if a contaminated vaccine lot causes infant deaths?

A contaminated vaccine lot killing infants collapses immunization confidence in one country — a localized public-health and vaccine-maker event, not a global mobility/oil shock; the crude cascade is too broad. Rhymes with the 2019 Samoa MMR crisis and India's DPT-scare episodes, which hit campaigns and confidence, not crude. Spillover is a small risk-off wobble plus pressure on the implicated manufacturer.

The class rate is measured from our dated, sourced event library (decade-normalized Poisson — the full table is public at base_rates.json). The variant’s share within its class is the analyst’s editorial call, published so you can audit it. A wider range means thinner precedent. Full recipe: methodology · scored at Reality Check.

How this trigger trickles across markets, left → right — the root shock, its first‑order moves, then the ripple effects. Drag any node; tap a market for its real price history.

Resolution timeline — how this probability is moving

Our model's odds (gold) over time vs the crowd's (Polymarket, blue), from the past toward the 0–6 months horizon. Each dot is a real macro event that nudged the probability — green pushed it up, red pushed it down. Tap a dot for the source. The gold path is an illustrative reconstruction anchored to today's estimate — real dated events, not a live re-estimate history.

What it would mean

If this plays out, it is a risk-off shock. Contaminated vaccine lot causes infant deaths in a large country, collapsing vaccine confidence and halting immunization campaigns. The trigger decomposes into signed root‑shocks — Risk appetite ▼ · Pandemic shock ▲ — which propagate through our causal graph to the markets below.

If it happens — the markets it would move

Biggest moves first. Projected moves are cascade-model priors; hist A–B% = what comparable past events actually did (measured abnormal returns), and model prior · unmeasured marks markets with no analogue backing yet. Tap any market for its price history.

Probable recommendation

If the scenario above plays out, the probable cross‑asset positioning → a scenario‑conditional read, not personalized investment advice
Cash / hedgeRaise cash and hold the long hedges above; this scenario is net risk-off.
For a common-man portfolio: A typical stock-heavy portfolio is at risk. Consider trimming equities, raising cash, and a small gold hedge.
Also moves (not yet on Hyperliquid): United Airlines +0.2% · ExxonMobil -0.2% · Chevron -0.2% · Delta +0.2%

Why we may diverge from history

Trust history-short on UAL/DAL: airlines crater in a deadly-pathogen scare; the -14% is clean on-channel COVID-2020 evidence, the cascade's contrarian long ignores the demand-shock transmission.

Historical precedent — what analogous events actually did

Across 40 analogous events (overlap‑weighted), as abnormal returns — market beta stripped, so it's the event's own effect, not the market backdrop. Shown at 20 days (persistent) and 5 days (immediate); ↺ fades = the two horizons disagree. Confidence = consistency × sample × significance.

Why this probability

Contaminated-lot infant deaths recur historically in LMICs; confidence-collapsing event within 6mo modest. A base‑rate‑anchored prior, continuously scored against what actually happens — not a forecast.

Methodology. Probability and impact are anchored to history and scored against what actually happens — wins and losses, in public, at Reality Check. Crowd odds live from Polymarket & Kalshi. By Vikas Singh, Quantitative Strategist. Updated 2026-07-03.
