A recent testimony before Germany’s parliament has reignited debate over COVID-19 vaccine safety, drawing attention from political figures, tech leaders, and public health experts alike. But while the claims are making headlines, they are also being strongly challenged by scientists and regulators.
Here’s a clear breakdown of what was said, what it means, and how it compares with established evidence.
What Did Helmut Sterz Claim Before the German Parliament?
Helmut Sterz, a former toxicology head at Pfizer’s European centers, testified before the German Bundestag’s Corona Enquete Commission on March 19, 2026.
Key Allegations:
- Long-term safety studies—including carcinogenicity assessments—were not completed before vaccine rollout
- Around 10 preclinical safety studies were allegedly skipped
- Vaccine-related deaths in Germany may be significantly underreported
Sterz’s testimony suggests that the rapid development and emergency rollout of COVID-19 vaccines may have bypassed certain standard procedures.
What Is the Claim About Vaccine-Related Deaths in Germany?
Sterz cited data from Paul-Ehrlich-Institut, which recorded 2,133 reported deaths following vaccination.
He then applied a controversial multiplier:
- 30× adjustment factor → Estimated ~63,990 deaths
Where Does the Multiplier Come From?
The figure is derived from a study involving Harvard Pilgrim Health Care, which suggested that fewer than 1% of adverse events may be reported in passive surveillance systems.
Why Experts Are Challenging This Calculation
Public health officials and researchers have strongly pushed back on this methodology.
1. Correlation vs. Causation
Reported deaths after vaccination are not automatically caused by vaccines. Surveillance systems track events that occur after vaccination—not necessarily because of it.
2. Limits of Passive Reporting Systems
Agencies like the U.S. Department of Health warn that systems such as VAERS:
- Are designed for signal detection, not definitive conclusions
- Cannot be used to calculate actual death rates
3. Multiplier Misuse
Experts argue that applying a generalized “underreporting multiplier”:
- Ignores differences in national healthcare systems
- Assumes uniform underreporting across countries
- Can dramatically inflate estimates without evidence
4. Germany’s Reporting Standards
Germany’s pharmacovigilance system is considered relatively robust, making a blanket 30× adjustment particularly questionable.
How Did German Officials Respond?
Karl Lauterbach dismissed Sterz’s claims during the session, calling them inaccurate.
Health authorities maintain that:
- COVID-19 vaccines underwent rigorous testing
- Ongoing monitoring continues to support their safety profile
- The benefits outweigh known risks
What Does the Broader Scientific Evidence Say?
Large-scale studies and global health organizations offer a more comprehensive view.
Evidence from Peer-Reviewed Research
- Studies published in The Lancet show that higher vaccination rates correlate with lower mortality rates
- Vaccines significantly reduced:
- Severe illness
- Hospitalization
- Death rates during peak waves
Global Health Consensus
The World Health Organization continues to support COVID-19 vaccines as:
- Safe for the vast majority of people
- Essential in managing the pandemic
- A key factor in reducing healthcare system strain
Where Does Elon Musk Fit Into This?
Elon Musk has publicly supported Sterz’s claims, amplifying them on the social media platform X.
He has previously:
- Shared personal experiences with vaccine side effects
- Expressed skepticism about COVID-19 risks
- Made controversial claims linking vaccines to health events without verified evidence
While influential, Musk’s statements are not based on peer-reviewed scientific research, and experts caution against treating them as medical evidence.
Why Vaccine Skepticism Persists
Even years after the peak of the pandemic, vaccine debates remain active.
Key Drivers:
- Mistrust in institutions
- Complex scientific data that is easy to misinterpret
- Amplification on social media
- High-profile endorsements of controversial views
This environment allows isolated claims to gain traction—even when they conflict with broader scientific consensus.
How to Evaluate Claims Like These
For readers trying to make sense of conflicting information, a few principles can help:
1. Check the Source
- Is the claim backed by peer-reviewed research?
- Is it supported by multiple independent studies?
2. Understand the Data Type
- Observational reports ≠ proven causation
- Surveillance systems are early warning tools, not final verdicts
3. Look for Scientific Consensus
- What do major health organizations say?
- Are findings consistent across countries?
4. Be Wary of Large Multipliers
- Dramatic estimates often rely on assumptions that may not hold
The Bottom Line
The testimony by Helmut Sterz has sparked renewed debate—but it remains highly contested.
- His claims about skipped studies and underreported deaths lack broad scientific backing
- The use of a 30× multiplier is widely criticised by experts
- Extensive global data continues to support the safety and effectiveness of COVID-19 vaccines
In a landscape shaped by both science and skepticism, the key challenge isn’t just accessing information—it’s interpreting it correctly.
TL;DR
- A former Pfizer toxicologist claimed COVID-19 vaccines skipped key safety studies.
- He estimated ~63,990 vaccine-related deaths in Germany using a disputed multiplier.
- German officials and experts strongly reject these claims.
- Research from The Lancet and the World Health Organization supports vaccine safety and effectiveness.
- Misinterpretation of data and social media amplification continue to fuel skepticism.
