Does contracting measles prevent cancer?

Studies suggest that the measles virus, when engineered in a lab, shows promise as a cancer drug. But no evidence suggests that naturally contracted measles prevents cancer, and experts warn against virotherapy research influencing attitudes towards measles, mumps and rubella vaccines.

A study using mice found that exposure to engineered measles regressed ovarian tumor cells by 80%. Over 150 clinical trials of cancer patients who were administered engineered measles showed promising results for various cancers.

However, experts studying the measles virus as a potential cancer therapy say their research is being incorrectly cited as part of anti-vaccination campaigns. They note that:

  • Measles killed 110,000 people globally in 2017. They unequivocally advise vaccination against MMR.
  • Evidence of measles as a cancer therapy shows the engineered virus is most effective in patients who have received the MMR vaccine.

ABOUT THE CONTRIBUTOR
Between 2020 and 2022, under close editorial supervision, Gigafact contracted a group of freelance writers and editors to test the concepts for fact briefs and provide inputs to our software development process. We call this effort Gigafact Foundry. Over the course of these two years, Gigafact Foundry writers published over 1500 fact briefs in response to claims they found online. Their important work forms the basis of Gigafact formats and editorial guidelines, and is available to the public on Gigafact.org. Readers should be aware that while there is still a lot of relevant information to be found, not all fact briefs produced by Gigafact Foundry reflect Gigafact's current methods and standards for fact briefs. If you come across any that you feel are out of date and need to be looked at with fresh eyes, don't hesitate to contact us at support@gigafact.org.
