why we need to tackle our silent viral stowaways
There may finally be a vaccine and a treatment for one of the most successful and annoying viruses.
When we think of viruses, we usually think of something like COVID, or SARS, or Ebola, or recently, hantavirus. Something that frequently, if not usually kills its host, or takes us out for a few weeks. But the most successful viruses not only don't kill their hosts, living out their lifecycles and mutating at their leisure, they don't even cause symptoms. We don't know we've been infected, or that anything is wrong, and when it is, it's something that seems completely unrelated.
This is the cause with the Epstein-Barr Virus, or EBV. Named after British pathologist Michael Epstein and Irish virologist Yvonne Barr – so no, not the Epstein and Barr we all know and loathe – it's one the world's most prolific and stealthiest infections estimated to be living in 95% of adults. There are no signs anything is amiss. The virus almost feels downright benign, which is why no one seems to worry all that much about it.
Even worse, it evolved the very annoying ability to attach itself to virtually all our B cells, blinding our immune systems, so creating a vaccine for it has been a major challenge, and the lack of attention to it means that it sits in our bodies for decades giving us increased risks of mono and a variety of lymph node, gastric, and nasal cancers, and for good measure, just to put a turd topping on this shit sundae, a handful of autoimmune diseases.
However, it turns out that two EBV proteins, gp350 and gp42, trigger a special immune response in mice that were genetically modified to produce human antibodies, and at least one of these antibodies seemed to prevent the virus from infecting the lab mice, meaning that it may be possible to make a human vaccine and significantly lower the rates of everything from the aforementioned grim compendium of diseases with proper therapy and herd immunity.
We've seen a similarly positive effect with vaccines against HPV, which notably lowered the rates of cervical and oral cancers. This kind of research may be in the crosshairs of the pro-disease movement, which hates vaccines and advocates eugenics by attrition, but scientists who actually want to lower the rates of chronic disease and cancers, and enable our bodies to fight them better, see this sort of research as a way to save and prolong tens of millions of lives.
Letting viruses just hang out in our bodes because they're not actively making us feel sick doesn't mean they're not actually doing tremendous damage. So, expect more and more efforts to combat viruses like EBV and similar silent biological hitchhikers, and more vaccines and therapies that involve training our immune systems to go after proteins that used to trick them into turning a blind eye to whatever viral shenanigans were happening unchecked.
