The only evolution I see in medicine is when it comes to the ability to do surgery and save lives in trauma treatment. There has been tremendous progress there. Anything else is mired in corporate and depopulation obsessed corruption. We don't even have decent nutrition data out - just more propaganda and nonsense added and promoted. I would rather call most preventive and treatment-related medicine a devolution and not an evolution. Even the madness of the food pyramid with the promotion of carbs and seed oils did more damage to the health of humanity than any potentially life-saving surgeries.
As for vaccines - we may find out some day that they were only relatively benign because there were so few of them up until the 1980s. They may be proven to be nothing else but poisonous arsenic injections by which the only thing you prove is that your kid or you are strong enough to survive some poison - you essentially attain nothing else. Might as well give your baby one teaspoon of rat poison and say that only 1 in 1000 is left with severe side effects or killed.
Or it might be the place where we throw the wicked with their wickedness;
To me it seems the "red pill" is quite comfortable! It needs no questioning of vaccines.
