Worn down? The whole planet is worn down by Big Pharma now!
I'm not.
Of Spanish flu, there is a good book ; Swine Flu Expose by Eleanor I. McBean
Do you mean the anti-vax kook who wrote "Poisoned Needle"? Wow! She's a nutter.
She argued that 1918 wasn't even a flu, but rather the result of vaccinations given to soldiers. Of course, here in the real world we have tissue samples from victims that allowed modern gene sequencing that confirmed it was a flu. We even have studies of survivors showing they have antibodies to that virus. And, of course, the 1918 flu wasn't confined to killing soldiers. It cut through populations of non-soldiers far from any battlefield, because the disease was caused not by vaccine poisoning, as she'd have it, but by a virus that could be transmitted from person to person.
Have you actually read her garbage? Give it a try. For example, her ravings in the Poisoned Needle include the idea that germs don't actually cause disease. "Isolated germs have never been known to attack and cause decay and disease of any part of the body." She insists that the disease actually comes from poisons, like vaccines, and that the presence of bacteria and other organisms in the diseased are just because they're "part of decayed substance." "Bacteria do not cause pathology but are rather the effects of disease.... bacteria does not and cannot produce disease in a healthy organism"
In other words, if you've got, say, malaria, it has nothing to do with the malaria parasite present in all people with malaria. Rather, that parasite is just a side effect of you having malaria, which was actually caused by some other poison, like a vaccine. If you took a healthy person and injected him with the malaria parasites, he'd be fine, according to this dim bulb. Same with the smallpox virus, anthrax bacteria, and so on. All those things evolved from the decay of the body following a poisoning, rather than being the cause of the illness.
That is, of course, utter lunacy. We have countless examples of isolated germs causing disease -- including lots of examples of scientists who are researching germs becoming accidentally infected and getting sick.
This is why one should rely on actual experts in understanding illness, not fringe lay people like Eleanor McBean.
