As in other sectors, this is like a 2-yr old refusing to drink their milk. Even a small glimpse into history reveals the ravages of infectious disease and the great triumph of vaccines and antibiotics. As a senior, I remember all those affected by polio, the rollout of the vaccine, and virtual eradication. The thing is, cancer, Alzheimer's, Autoimmune, cardiovascular diseases appear to have ever stronger viral linkage, so mRNA vaccine development is needed more than ever. Naturally, checks and balances are also in order, to make sure standards of safety & efficacy are in place (Will they? In a money & populist-driven DJT regime?)
My Dad was a large animal Vet, so I'm keenly aware of zoonotic diseases and also health/nutrition. We had 400 free range chickens once, drank raw milk, could see the benefits of "natural", but I darn sure kept the quality controls and vaxes up. The confusion is perhaps "if some natural remedy is good, a lot is better", not realizing that the epidemiological "bad boys" don't care how much fresh air, sunlight, healthy food you've had.
