Somewhere along the line, medicine has become focused on treating symptoms, not the causes.
Needless to say, there is more money in selling whatever treats the symptoms than there is in selling a one-shot cure.
Unfortunately, that means people are living with unnecessary pain and degenerating health when they could be healthy.
I noticed and commented on studies during COVID which were constructed to show little or no effect for the HCQ and IVM regimens including an antibiotic and zinc, by administering the IVM or HCQ to patients with advanced symptoms, often without the antibiotic and always without the zinc supplement (the reason for the HCQ or IVM was to act a an ionophore for the zinc, which disrupted viral replication).
I don't know who approved the 'studies', or who funded them, but they were constructed to provide a given outcome: either failure of the drug to make any difference, or to even show it to be harmful. Either outcome would discredit the regimens as treatments leaving the way clear to maintain the Emergency Use Authorization for the "vaccines", which resulted in billions of dollars in revenue for Pharma companies, much of it from our tax money.
Coincidentally, obtaining IVM or HCQ became far more difficult, even for patients who were taking HCQ for conditions like Lupus or RA, and had been for years. Another 'coincidence': Thomas Laboratories, which had been a well known supplier of veterinary antibiotics (which were often stocked by preppers and were used by humans despite admonitions that they were not for human use--the antibiotics were commonly identical in appearance and stated contents for those used by humans, in dosages commonly prescribed for humans) stopped producing the entire antibiotic product line. Some sources on the web have said this was due to political pressure, as the antibiotics for fish and birds were often sourced from the same manufacturers which produced human antibiotics. Antibiotics for other animals may contain additional substances harmful to humans, but the fish antibiotics commonly contained only the antibiotic itself as an active ingredient. Doxycycline for birds similarly contained only the antibiotic.
https://www.doomandbloom.net/the-case-for-fish-antibiotics/In 2024, the FDA required a prescription for animal antibiotics, ending the ability of preppers or those who would take those antibiotics without MD supervision to obtain them without a doctor in the middle.
BTW, I had kept a stock of those (sadly gone now), with some that traveled with me in the field to combat pulmonary or other infections that might pop up hundreds of miles from home. They worked, without unwelcome effects.
