# Audit: COVID-19 vaccines killed 20,000 to 60,000 people in Germany (as claimed in Dr. Helmut Sterz's March 19, 2026 parliamentary testimony and amplified by Elon Musk on April 12).

## Claim Interpretation

The natural-language claim asserts that COVID-19 vaccines caused ("killed") between 20,000 and 60,000 deaths in Germany, attributing this claim to Dr. Helmut Sterz's March 19, 2026 testimony before the German Bundestag and noting its amplification by Elon Musk on April 12, 2026.

The claim uses the causal language "killed," which asserts a direct causal relationship between vaccination and deaths. This is operationalized as a contested qualifier compound claim: SC1 verifies that the assertion was made and amplified as described (provenance), while SC2 tests whether the causal claim has independent scientific support (epistemic warrant).

**Formalization scope:** The natural-language claim bundles a factual event (the testimony and amplification) with a causal assertion (vaccines killed people). The formal interpretation faithfully captures both dimensions. The phrase "as claimed in" is interpreted as attributing the claim's origin, not as endorsing its truth — the proof evaluates both the provenance and the truth of the underlying causal assertion.

**B1 — FactCheck.org:**
- Status: verified
- Method: full_quote
- Fetch mode: live
- Verbatim status: verbatim (default)

**B2 — NewsBytes:**
- Status: verified
- Method: full_quote
- Fetch mode: live
- Verbatim status: verbatim: False — this quote is a close paraphrase. Evidentiary weight reduced, but the provenance fact (Sterz testified on March 19, 2026) is independently confirmed by B1 and B3.

## Computation Traces

```
SC1: Provenance — Sterz made the claim and Musk amplified it: 3 >= 3 = True
SC2: Scientific support — vaccines killed 20k-60k in Germany: 0 >= 3 = False
compound: all sub-claims hold: 1 == 2 = False
```

## Independent Source Agreement (Rule 6)

### SC1 (Provenance)

Three independent publications confirm the provenance: FactCheck.org (Annenberg Public Policy Center), NewsBytes, and BusinessToday India. These are editorially independent organizations with no organizational overlap.

COI assessment: No conflicts of interest identified. None of these sources have a stake in whether the testimony occurred or not.

### SC2 (Scientific Support)

Zero sources consulted. No independent scientific source could be identified that confirms vaccines caused 20,000–60,000 deaths in Germany. This is the expected outcome under the contested qualifier pattern — the absence of supporting evidence for SC2 is what produces the DISPROVED verdict.

## Adversarial Checks (Rule 5)

**Check 1: Does Sterz's methodology have scientific basis?**
- Searched: FactCheck.org, VAERS FAQ, Science Feedback, NewsGuard Reality Check
- Finding: No credible pharmacovigilance authority endorses multiplying passive surveillance death reports by a fixed underreporting factor to estimate causal deaths. Multiple independent experts explicitly reject the methodology.
- Breaks proof: No — this counter-evidence reinforces the DISPROVED verdict for SC2.

**Check 2: Did PEI attribute 20,000-60,000 deaths to vaccines?**
- Searched: PEI official pharmacovigilance report (March 2025)
- Finding: PEI assessed only 28 deaths as "possibly or probably" related to Pfizer vaccination (74 across all COVID vaccines). PEI explicitly states passive reports cannot determine causation.
- Breaks proof: No — the official regulator's own data contradicts the claimed figure by orders of magnitude.

**Check 3: Do epidemiological studies show vaccines increased mortality?**
- Searched: Peer-reviewed literature on COVID vaccine mortality
- Finding: Large studies consistently find vaccines reduced mortality. No peer-reviewed study supports the 20,000–60,000 figure.
- Breaks proof: No — the weight of epidemiological evidence runs counter to the claim.

**Check 4: Is there any credible evidence supporting the claim?**
- Searched: Studies on vaccine-caused excess mortality in Germany
- Finding: One ecological study noted a vaccination-rate/excess-mortality correlation but explicitly disclaimed causal inference and did not support the specific death count.
- Breaks proof: No — the strongest available evidence in the claim's direction explicitly disclaims the causal inference the claim requires.

## Source Credibility Assessment

| Fact ID | Domain | Type | Note |
|---------|--------|------|------|
| B1 | factcheck.org | Unclassified | FactCheck.org is a project of the Annenberg Public Policy Center at the University of Pennsylvania; widely recognized as a reputable fact-checking organization |
| B2 | newsbytesapp.com | Unclassified | NewsBytes is a news aggregator/fact-check site |
| B3 | businesstoday.in | Unclassified | BusinessToday is a major Indian business news publication owned by the India Today Group |

All three sources are classified as "unclassified" (tier 2) by the automated credibility system. However, FactCheck.org is an IFCN-certified fact-checking organization affiliated with the University of Pennsylvania. The tier 2 classification reflects the automated system's coverage limitations, not actual source quality concerns.
