Scientists are making rapid progress toward a long-awaited goal that could help to reshape cancer care: with the potential to significantly to .
Since the early 2000s, there have been testing the use of mRNA vaccines to treat multiple cancer types, such as , , , and cancer.
At the same time, misinformation about so-called began spreading widely on social media, with mainstream media outlets on it in late 2022. Turbo cancer refers to the that COVID-19 mRNA vaccines cause unusually aggressive cancers.
who , I have seen how quickly new misinformation can spread and the impact it can have on people’s health decisions. In the case of mRNA cancer vaccines, this false narrative could undermine public confidence in an important tool that may help prevent or treat cancer in the future.
Cancer research and mRNA vaccines
Most people likely first heard about through COVID-19 vaccines, but scientists have been .
How is by delivering instructions that prompt the body’s cells to make specific proteins. This process teaches the immune system how to recognize and attack those proteins. In cancer research, scientists can design that train the immune system to find tumor cells and more effectively kill them without harming healthy cells.
One example of this potential comes from studies on with few effective treatments. Researchers have found that a can rapidly activate people’s immune systems against this type of brain cancer and improve survival.
The body of evidence that mRNA vaccines can transform how researchers is growing. However, even the most promising medical advances can only improve health if people are willing to use them.
Rise of the ‘turbo cancer’ narrative
“” is a term often used by anti-vaccine advocates who claim – without credible evidence – that COVID-19 mRNA vaccines are causing unusually aggressive cancers.
This inaccurate narrative has trickled into the mainstream news. In September 2025, a controversial U.K. cardiologist claimed that the COVID-19 vaccine contributed to the royal family’s recent cancer diagnoses, spurring . Although uncommon, some public figures and health professionals have claimed that the vaccines could cause cancer despite , often by misinterpreting or misrepresenting studies.
can be described as shared with the public that are not supported by scientific evidence, are based on unverified personal stories or are opinions presented as facts. For example, while tracking discussions about the HPV vaccine across social media platforms, my team and I found that were widespread online.
Vaccine misinformation accelerated during the , causing what researchers call : the rapid spread of both accurate and false health information during a public health crisis. The COVID-19 infodemic made it harder for people to find trustworthy guidance and shaped public attitudes toward vaccines.
“Turbo cancer” reflects many of the same patterns and narratives as the COVID-19 infodemic.
In a study, which involves systematically monitoring online conversations about different topics, my team and I observed countless posts about turbo cancer beginning in July 2023 and continuing through early 2026. Many posts rely on emotionally compelling anecdotes, misinterpretations of animal studies, misuse of adverse events reporting and recycled myths that vaccines alter human DNA. Some posts also link to the COVID-19 vaccine. However, have found no increased cancer risk following vaccination.
None of these turbo cancer claims are supported by . But on social media, repetition, personal stories and scientific-sounding language can make misinformation appear legitimate and help it .
Cancer vaccine misinformation harms health
At first glance, fringe claims such as turbo cancer may seem easy to dismiss. But research shows that they can have real-world consequences, and cancer-related misinformation can be particularly consequential.
Inaccurate information about cancer treatment is common online, and researchers have shown that it . When patients rely on unproven approaches instead of recommended therapies, their can increase substantially.
Clinicians are already seeing the effects of misinformation in routine care. having to address myths or misleading information that patients have encountered, though researchers do not yet know how common these conversations are across cancer care.
mRNA technology is entering a pivotal phase in its development. Scientific progress is accelerating, but public understanding has not kept pace. Repeated can erode trust in mRNA technology over time, increasing the likelihood that some patients will decline mRNA therapies in the future.
If misleading narratives such as turbo cancer continue to spread, they could complicate the future rollout of mRNA vaccines and limit their lifesaving benefits.
Keeping communication in pace with science
Once misinformation takes hold of public understanding, changing its course can be difficult.
Research has consistently shown that proactive, transparent and persuasive communication can . It also shows that trust, once lost, is .
Medical innovations can save lives, but . This means monitoring emerging misinformation trends on social media, addressing concerns early on, equipping clinicians to have and that builds public understanding of new medical technologies before they are widely introduced in the clinic.
Scientific innovation alone is not enough to improve health. Ensuring that the public can evaluate medical innovations like mRNA cancer vaccines based on evidence, rather than viral misinformation, is part of the scientific challenge.
The future of cancer care depends not just on scientific discovery, but on public understanding and trust.
