Throughout history new tools have often brought about unintended consequences in society and our new field of mRNA vaccines appear to fall into that category of possible ‘uh-oh.’ Multiple times, even in recent decades, initial excitement over drug discoveries has turned into dashed dreams and even scandals. With the COVID epidemic, mRNA technology, which had been chugging along normal development pipelines, was thrust into the starring role as humanity’s savior from the grave threat of SARS CoV2 virus. Now, facing papers like this, we need to tone down our enthusiasm and tap on the brakes. Prudence requires that we understand its potential secondary and tertiary unintended consequences before we continue with widespread use.
Before throwing mRNA wholly under the bus, we should put this single case study in perspective. This study is 1 patient who developed a very aggressive bladder cancer within the 12 months after receiving a 3 dose series of the Moderna mRNA COVID so-called vaccine (technology not a true vaccine). Causation cannot be proven at this point. This case report simply begs and pleads for further serious research into whether mRNA genes from this technology could be doing the same thing in others who received the shots. If we don’t put serious effort into assessing this needle in a haystack, we may miss the opportunity to avoid a world of harms to millions of people.
What did this patient’s evaluation actually show that links her cancer to mRNA? In the cancer’s cells, many oncogenic (cancer mechanisms) genetics were found. Within some of the genetic changes the researchers found a 20-base sequence of DNA that matched 20 bases from Pfizer’s mRNA injection. As Moderna had not submitted its mRNA genetic code to national databases, they only had Pfizer’s code to test for. The Pfizer and Moderna mRNA’s would be expected to share a lot of the same genetics, so this is entirely plausible.
The odds of these 20 DNA bases matching exactly is about 1 in a trillion. The genetic stretch where these 20 bases were found was in a highly variable region of the cancer cell’s DNA which could incorporate such mRNA fragments. The combination could contribute to increased expression of the cancer-causing proteins. Thus, the mRNA injection in the prior year for this patient could plausibly have triggered a cancer cascade in this patient, though we can’t say that for sure.
With all this in mind, if we want our patients and the public at large to enjoy a healthier, more abundant life, we should all agree that therapies contributing to cancer should be avoided. We don’t yet know for sure, but in light of these suspicions, medical science should step back and reconsider how widely we are using this new therapy. More studies are needed before multiplying the applications of this technology by replacing traditional vaccines. At the least, those being offered the mRNA injections should be informed of this risk. I don’t comprehend why these two requests are so hard to understand.
