A fake vaccine campaign was used to locate Osama bin Laden, fueling vaccine distrust

Palantir's software is widely speculated to have enabled Osama bin Laden's assassination

While Palantir has never publicly confirmed the use of its software in the 2011 assassination, its technology is widely speculated to have been a critical aspect of the operation. However, Palantir executives have never denied the claim, either, and have frequently commented on the software's important role in defending Western civilizations from terrorism.

Polio is currently circulating in only two countries but it remains difficult to eradicate

Wild polio virus is only endemic in two places. Afghanistan and Pakistan are the last two countries with naturally occurring polio cases. Vaccination campaigns have been plagued by misinformation, Taliban bans on vaccines, distrust of public health workers, and violence, including the killing of vaccinators.

Osama bin Laden declared jihad—a call for armed struggle framed as a religious duty—against the US in 1996.

Needle-free polio vaccines were offered in Afghanistan for the first time in 2026

Fear of needles has been one barrier to eradicating polio in Afghanistan. Vaccinators are now using a needle-free jet injector to deliver the vaccine through the skin—an approach that's previously been used in other locations. The inoculation includes the inactivated virus vaccine (the vaccine without any live virus in it).

Wastewater testing has detected genetic evidence of polio, triggering vaccine boosters

Sampling of wastewater in London in 2022 detected fragments of polio virus, suggesting a vaccine-derived version of polio may be circulating. No one became ill, but the finding did trigger calls for a renewed booster inoculation campaign.

The COVID-19 pandemic led to a decrease in immunizations in the US and worldwide

Public health funds and resources that were diverted to COVID-19 response reduced efforts to combat polio and vaccinations for polio and other diseases declined during the pandemic, putting more people at risk for polio.

The CIA once tried to poison Fidel Castro's milkshake during the Cold War.

Decades of instability in the Middle East gave rise to al-Qaida.

Conspiracy theories come from distrust in government, media, and institutions

Some believe JFK's assassination was orchestrated by larger networks rather than a lone shooter. Skeptics wondered how one unknown man could kill the most powerful person in America, and believed the CIA, FBI, or Soviet government played a role in the murder.

A major US-designed polio vaccine was first tested in the Soviet Union

Albert Sabin's live attenuated virus vaccine—requiring two drops in the mouth—didn't garner political support in the US, so it was tested in the Soviet Union in the late 1950s.

US intelligence warned in multiple reports of al-Qaida's plans to strike before 9/11.

Most polio cases today are vaccine-derived rather than naturally occuring

Weakened, live virus vaccines—which aren't offered in the US—carry a risk of virus being shed in the stool. Rarely, the shed virus mutates and leads to vaccine-derived polio infections. Most recent polio cases are genetically linked to those vaccines. As shown in this graphic, there are typically hundreds of vaccine-derived polio cases annually.

al-Qaida was founded in 1988 by Osama bin Laden

The group emerged in 1988 from the militant networks formed during the Soviet-Afghan War. Under Osama bin Laden's leadership, it combined jihadist ideology with global ambitions—eventually orchestrating attacks across Africa, the Middle East, Europe, and the United States.

Jonas Salk developed the first successful polio vaccine—and tested it on himself

The American medical researcher developed the inactivated virus vaccine from 1952 to 1955 and proved that it could prevent disease. He tested the virus on himself and his family in 1954 and then carried out formal clinical trials on more than 1.3 million children.

The FBI ran a covert campaign to discredit Dr. Martin Luther King Jr.

From 1963 to 1968, the FBI surveilled Dr. King with wiretaps, hotel bugs, informants, and anonymous threats, citing concerns about Communist influence—an effort later revealed through declassified files and documented in the film MLK/FBI.

A movie helped make JFK assassination conspiracies widespread

Oliver Stone's film "JFK" (1991) imagined the 1963 assassination of President John F. Kennedy as the result of a conspiracy by US government agents. Before the film, this belief was not common, but it became widely adopted afterward. The film's impact contributed to the release of major CIA files in subsequent decades.

US intelligence allegedly pursued more than 600 schemes to assassinate Fidel Castro

From exploding cigars and poisoned Cohibas to an infected scuba suit and plans to drug a TV studio with LSD, this account catalogs the CIA's strangest—and consistently unsuccessful—attempts to kill Fidel Castro over decades.

The Soviet-Afghan War empowered militant jihadist networks

US and Pakistani support for Afghan mujahideen in the 1980s inadvertently built the infrastructure—training camps, ideology, and global fighters—that later evolved into al-Qaeda's foundation.

The US military, concerned about potential deployments worldwide, has long funded experimental hantavirus vaccines and therapies.

Collaborations between the military, biotech, and academic researchers led to an experimental antibody treatment for the Andes hantavirus strain—the one that more readily passes between humans. As of spring 2026, it had only been tested in animals. The US Army has also tested a potential hantavirus vaccine in people. It published early findings in 2023 that seemed promising, eliciting some immune system response. (Some users may encounter a paywall.)

Live virus vaccines predated polio—that's how we vaccinate against smallpox

Since 1796, smallpox vaccines have used a live poxvirus related to smallpox. Yellow fever vaccines have used a live weakened form of the virus responsible for yellow fever since 1937.

Deepfake videos impersonating real doctors are spreading false medical advice

More than 100 videos, found primarily on Instagram and TikTok in August 2025, promoted products related to beauty, wellness and weight loss. While TikTok removed 94% of content violating its policies on AI-generated content, these deepfakes were watched and shared before removal, undermining public trust in medicine.

Read about Palantir's role in the COVID-19 vaccine rollout

Palantir developed Tiberius, a software service that supported the public-private partnership spearheaded by then-President Trump to roll out COVID-19 vaccines. The software tracked state-by-state vaccine allocations, as well as COVID-related hospitalizations.

An LSD scientist's role in a US mind control project

Within a decade of LSD's discovery, the US government had launched a secret initiative involving hypnosis and hallucinogens. LSD researcher Louis Jolyon West conducted experiments for the CIA's MKUltra project, which focused on the potential of mind control. He later took part in a criminal trial that hinged on testimony whose sourcing was seemingly inspired by MKUltra experiments. This article explores light shed by West's personal archive.

Maryland required cholera researchers to fly a yellow warning flag—signifying quarantine dangers in the 1970s

The number of infected people, measured over 70-some years and across all 50 states and the District of Columbia, declined significantly after vaccines were introduced.

Inactivated polio virus vaccine is the only one offered in the US—it contains no live virus

Inactivated polio virus vaccines cannot cause illness because the virus isn't alive. It's been the only polio inoculation offered in the United States since 2000 and provides almost complete protection

The Taliban provided al-Qaida with a safe haven in Afghanistan before 9/11 and returned to power in 2021

A fundamentalist Islamist movement, the Taliban ruled most of Afghanistan before 9/11, providing al-Qaida with training grounds and sanctuary. After 20 years of war, it regained power following the U.S. withdrawal in 2021.

The host of ‘The Dating Game’ claimed it was a CIA front

In his 1984 autobiography, “Confessions of a Dangerous Mind,” “Dating Game” host Chuck Barris claimed the show was a front concealing his true job as a contract assassin for the CIA. Despite skeptical responses and a lack of evidence, Barris continued to say the story was true. In 2002, screenwriter Charlie Kaufman adapted the book for the screen.

How the most famous Ebola book, The Hot Zone, which sold 3.5 million copies and was translated into 30 languages, got aspects of the disease so wrong.

The 2026 Ebola outbreak is hampered by a lack of vaccine against the relevant species of the virus, heightening the need for rapid tests to aid in disease control.

A pediatric journal ran 138 fictional case studies, and 61 were cited as real stories

The Canadian journal Paediatrics & Child Health issued corrections to 138 case studies published since 2000, acknowledging the cases were entirely fictional—a practice intended to protect patient privacy that was never disclosed to readers. At least 61 of the fabricated reports were cited as fact in other peer-reviewed journals a combined 218 times, including a 2006 Lancet article alleging an infant died from opioid-laced breast milk.

Doctors ignored women's pain as a nurse replaced their fentanyl with saline

This five-part podcast series, produced by Serial Productions, focuses on the experiences of women undergoing fertility treatments at a Yale clinic where a nurse secretly replaced pain medication with saline solution. This led to women experiencing excruciating pain during procedures, but the clinic downplayed or ignored their complaints.

Limited transparency soon after Chernobyl made it a source of conspiracy theories

Some rumors about the event became perceived as more reliable than the Soviet mass media, which had omitted key information during the early days of uncertainty. The resulting theories included CIA involvement in the disaster, three-headed birds, aliens, and a weaponized earthquake.

US secrets: Project Paperclip

The US launched Project Paperclip in 1946, covertly recruiting over 1,500 German scientists to advance American military and space programs. Among them was Wernher von Braun, a key architect of the V-2 rocket who later became instrumental in NASA’s Apollo missions. While these scientists accelerated technological breakthroughs, their recruitment raised moral debates about overlooking wartime affiliations in the name of progress—questions that remain unresolved today.
