Vaccine Safety Testing Is a Myth
The closer you look, the less it exists.
Most people assume vaccines are rigorously tested for safety before being injected into millions of children. They’re not.
What passes for safety testing in the vaccine world isn’t science—it’s theater. No placebo controls. Absurdly short follow-up periods. Underpowered studies.
To any reasonable person, this would be considered fraud. But when it comes to vaccines, it’s standard practice.
No placebo controls
To determine whether a new drug is safe, you test it against a placebo.
A placebo is something inert, meaning it produces no effect on the human body.
Without this neutral baseline, there’s no way to know for sure what a product does.
It’s what allows you to tell whether the outcomes you see are caused by the product you’re testing—or not.
The FDA confirms this in the package inserts for each vaccine, available on their website.
That alone should stop the conversation.
Because without a placebo control, claims about vaccine safety rest on faith, not fact.
What they use instead
Instead of a placebo, vaccines are tested against other vaccines, or injections containing active ingredients like aluminum adjuvants.
If both test and control groups show similar rates of adverse effects, the manufacturer can claim, “See? No difference—the vaccine is safe.”
It’s like comparing whiskey to vodka and claiming whiskey has no effect because both get you just as drunk.
The FDA allows this practice. The CDC defends it. The media ignores it.
Here’s a snapshot showing what (if any) controls were relied upon to license every routine childhood vaccine in the United States:
Vaccine trial pyramid scheme
You might think that, even though none of the vaccines are tested against a placebo, surely they’re at least compared to something that was. They’re not.
Newer vaccines are tested against older ones—but those older vaccines were often tested against yet another vaccine instead of a placebo.
And that one? Same story.
Safety claims for each vaccine rest on the assumption that the vaccine it was compared to was properly tested—but peel back the layers, and there’s no placebo control anywhere along the chain.
None of the routine childhood vaccines were licensed based on trials that used a placebo—or even a control that was.

Absurdly short safety review periods
Even if we ignore the lack of placebo controls, the safety review periods for vaccines are absurdly short—sometimes only three days.
Childhood vaccines typically get just a few days or weeks of monitoring—never more than six months—yet developmental, neurological, and immune disorders (such as autism, ADHD, allergies, etc.) often don’t appear until years later.
In other words, these trials cannot capture harms that emerge years after vaccination.

By contrast, while routine childhood vaccines are monitored for only a brief period, other widely used drugs undergo multi-year trials before approval.
Such brief follow-ups for vaccines cannot capture long-term risks.
Underpowered studies
Even if there were placebo-controlled trials—which there aren’t—and even if the follow-up periods were long enough—which they aren’t—many vaccine studies would still fail to reveal real harms because they are severely underpowered (meaning they include too few participants to detect rare or serious adverse effects).
Many routine childhood vaccine trials enroll only a few hundred or a few thousand children. If a vaccine causes a chronic health condition in 1 in 1,000 children, a trial of 500 would likely miss it.
Post-licensure monitoring
Some may claim that VAERS (Vaccine Adverse Event Reporting System) monitors vaccines post-licensure to ensure their long-term safety.
In reality, VAERS is a passive system that captures “fewer than 1% of vaccine adverse events”—meaning most vaccine injuries are never recorded.
Conclusion
None of the routine childhood vaccines were ever licensed based on long-term, placebo-controlled trials.
When injuries occur, agencies like the CDC and FDA dismiss them with the standard line: “No causal link has been established.” They never explain why no causal link has been established—because without placebo-controlled trials, there is no way to prove it. The system is structured to avoid detecting the very harms it is supposed to protect the public against.
The failure to conduct long-term, placebo-controlled trials for the licensure of routine childhood vaccines is scientifically and morally unjustifiable.
And it remains standard practice.

Isn't it odd that the "rules" of "evidence-based medicine," such as requiring randomized, placebo-controlled trials are turned off for vaccines? And these are given to perfectly healthy babies, children and others, so should have a higher standard for safety than other products.
It's all a huge scam, including "evidence-based medicine."
Not just vaccines, but many drugs follow this path to marketing. You see, all these vaccines and drugs are powerful chemically derived poisons very toxic to the body. You have to cut many corners and have a paid off FDA/CDC to get these toxins to the public.
This real silliness of all this is that the FDA does NO drug or vaccine testing of its own. NONE! It completely depends on the drug companies to do their own testing. How horrid is that? Let's have the mafia run the banking system...oh wait, it already does. But you get the idea.
