And memes like this tell me you're not ready. This study may or may not prove causation. Some caveats:
"What I think we're very likely seeing in this study is nothing more than a failure to correct for screening intensity, along with other potential confounders, so that the likelihood that people who were vaccinated and boosted were more likely to undergo screening," Gorski wrote.
In a similar vein, vaccine studies can lead to unmasking, where "someone comes in for a vaccine but a doctor runs a test and may find [something else]," Robert Bednarczyk, PhD, an epidemiologist at the Rollins School of Public Health at Emory University in Atlanta, told MedPage Today.
"So it may look like something arises after vaccination, but it's just that sheer act of going in for medical care, for the vaccine, that can lead to unmasking something that was already there," he added.
Becky Smullin Dawson, PhD, an epidemiologist at Allegheny College in Meadville, Pennsylvania, said another red flag in the study is that it didn't measure confounders typically assessed in a cancer study, such as family and screening history.
In addition, there was "only 1 year of follow-up for a cancer study, which is bonkers," she said.
Bednarczyk agreed that assessing a risk at 1 year was odd, "knowing that cancers take a long time to develop." The researchers also examined outcomes after just 1 month, "which feels biologically implausible," he said.
