Sure, I don't mind explaining what I mean. You seem to not understand how medical evidence works. The placebo effect is real, so you don't judge whether or not a medicine works based on a sample of one, or without a control group. Different people react to diseases and medicines differently, so you used randomization between the control group and the study group to even the differences out. You also try to randomize for comorbidities and other confounders between the two groups. And, for the best standard, you double-blind the study so the people running the study and the patients don't know who is getting what drugs. This is for bias and the placebo effect. You also should do a bunch of other things, like have large sample sizes to ensure you can statistically measure the effect you're looking for, and pre-register your end points to prevent p-hacking or changing end points to match results. So your experience of ivermectin working is - in medical evidence terms - completely useless. Other posters on here have the same problem. Not to mention the fact that several posters who were taking ivermectin for prophylaxis ended up getting sick, and others who took it as a therapeutic ended up having a severe course of the disease. At any rate, you had an average course of disease that would have been expected had you done nothing, so even on an anecdotal basis your evidence is not very compelling.
I can't speak to what the American people were sold. That's pretty difficult to confirm. What is easy to confirm is what the vaccines were designed to do. You can see that in how they structured the clinical trials, which I linked earlier. What they tested for was prevention of symptomatic disease - not infection. They also tested for severe disease and hospitalization. Local infection, like tested for by a nose swab, is pretty difficult to prevent. Vaccines that provide complete immunity give what is called "sterilizing immunity". These are pretty rare, and may not exist at all.
This is a really good article that covers the basics of vaccines. Its from 2010, so you can trust it if recent changes worry you. If you like, read only the "General Principles" portion and the "Viruses that infect the Mucosae" sections.
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2897268/What you'll find is that the efficacy of a vaccine is a *significantly* more complicated subject than "works/doesnt work" based on a nose swab. There's also several layers of immune defense - cellular immunity and humoral immunity are two parts of the adaptive immune system. Different vaccines stimulate these systems in different ways - which produce different amounts of protection.
If you do further research you'll also find that it's very common for vaccines to produce waning immunity over time, and that depending on the type of illness you're vaccinating for the efficacy of a vaccine and how long it lasts is all over the map. You'll also find that most of the vaccines we take today require multiple doses - three or four is not uncommon.
At any rate, when studies have been done that do random surveillance of people who have been given a vaccine vs people who haven't, they have actually found that the vaccines do in fact reduce the chance of getting infected. I linked a study to that effect earlier. You can read it here.
https://www.nature.com/articles/s41591-021-01548-7It isn't perfect protection - but then, the fact is no vaccine offers perfect protection, and respiratory viruses are not good candidates for sterilizing immunity. The fact that the virus has mutated in a way that evades the specific target of the mRNA vaccines makes the situation worse.
However, because of the different layers of the immune system, even as one layer (antibodies) seems to fade over time and also be less effective against different variants, the other layer (cellular response) seems to be very robust. The result is that people have local or minor infections but avoid the systemic and severe end of the spectrum at a high rate.
Public policy is a bit of a moving target. Reducing total infections is great, but at the end of the day infections aren't really relevant. Even minor illness doesn't matter. The real target is preventing severe disease - hospitalizations. I think intuitively everyone agrees with this, but the communication by public health officials has been pretty bad throughout the pandemic. To be sure if you reduce the number of total infections (which the vaccines absolutely do, even if imperfectly) you reduce the number of hospitalizations. But these vaccines also absolutely reduce the proportion of infections which go on to become symptomatic and severe, which also reduce hospitalizations. This is why vaccines are so important. Even now with Omicron significantly reducing the efficacy of the vaccines, the odds ratio of hospitalization for people who have had two rounds of mRNA vaccines vs people who have not is 70%. Meaning if you vaccinate half of a large group of people at random and 100 people end up in the hospital, 30 will be vaccinated and 70 will not. Against delta the number was in the 90s.
Hope that clarifies my comments.
