Anti-vaccine activists tend to grab onto any story that supports their narratives about vaccines. Generally, they comb the internet for any article that either tells us that vaccines don’t work, that they’re dangerous, or that the disease prevented is innocuous. It’s a frustrating process. Recently, an article was published that seemed to indicate chickenpox prevents glioma, a rare group of cancers that arise in the brain or spine. Then, by extension, some have claimed that not being vaccinated against chickenpox helps prevent glioma.
But is this valid? What does the evidence say about chickenpox and glioma? Is it even plausible that chickenpox has some biological relationship to glioma?
As always, answers aren’t as simple as the anti-vaccine group would like them to be. It’s complicated, as most science is.
