Oh for heaven's sake!
Of course I made the above post about
immunity as a joke, but then, just for the heck of it, I did a little searching, and, lo and behold, there really is
research going on using vaccine made from flu virus to attack cancer tumors!
The article below, from last December, talks about
ways this is being studied. From the article:"This is one of those ideas that seems nuts but had so many earlier results pointing toward it working that it was really just a matter of time before someone tried it."
"... the researchers identified over 30,000 people being treated for lung cancer and found those who also received an influenza diagnosis. You might expect that the combination of the flu and cancer would be very difficult for those patients, but instead, they had lower mortality than the patients who didn't get the flu."
"Having an active influenza virus infection reduced the ability of the melanoma cells to establish themselves in the lung."
But then the article goes on to discuss problems that would need to be overcome for this technique to be the basis of a successful form of treatment, so it's no given that this approach is ultimately the way to go.
And all this probably has nothing to do with the coronavirus, and it may well be, as is often the case, that it's going to be something that works in mice, but not people.
But wouldn't it be so ironic
if it someday is shown that a thing as nasty as a flu virus turned out to be a cancer fighter in people! https://arstechnica.com/science/2019/12/injecting-the-flu-vaccine-into-a-tumor-gets-the-immune-system-to-attack-it/
