A story in the New York Times reports that scientists are learning that avian flu has acquired airborne transmission ability after it was modified for increased strength. The experiments were part of studies to learn how the virus behaves. Now this virus can survive in the nose of ferrets, mammals whose nostril temperature is 4 degrees C cooler than a bird’s gut, where H5N1 usually grows.
The article points out that there’s a difference in ferret noses and those of us higher order mammals. One point cannot be smoothed out, however. The crossover point of animal to human is a step closer after this discovery. That kind of crossover is a prospect for triggering a pandemic.
Cancers are caused by viruses. (So many diseases start with a virus.) A new drug might be able to treat people who already have a cancer, by employing the body’s natural immunity T-cells to attack cancer cells. No mention in this link about availability of the drug, but since it’s developed outside the US, approval can be much swifter. You’d still need traditional chemo/surgery for advanced cancers. But this is a novel way to get a pharma solution to ally with natural immunity. If you can afford the booster shots.
This is the kind of medicine that the PharmAlliance wants to create in Viral Times. There is the US government in the way of approving that drug, in my future of 2021. But for now, here’s the early report on ImMucin.
A traditional vaccine helps the body’s immune system fend off foreign invaders such as bacteria or viruses, and is administered to people who have not yet had the ailment. Therapeutic vaccines, like the one Vaxil has developed, are given to sick people, and work more like a drug.
Vaxil’s lead product, ImMucin, activates the immune system by “training” T-cells –– the immune cells that protect the body by searching out and destroying cells that display a specific molecule (or marker) called MUC1. MUC1 is typically found only on cancer cells and not on healthy cells. The T-cells don’t attack any cells without MUC1, meaning there are no side effects unlike traditional cancer treatments. More than 90% of different cancers have MUC1 on their cells, which indicates the potential for this vaccine.
ImMucin is foreseen as a long-term strategy — a shot every few months, with no side effects — to stop the cancer from reoccurring after initial treatments, by ensuring that the patient’s own immune system keeps it under control.
