Antoine Bechamp's theory led to his discovery of the organic molecules that created the 1st microorganisms in a primordial soup billions of years ago in a process called abiogenesis. His discovery of organic molecules is the reason he is called the founder of organic chemistry.
His theory also led to his discovery of the microbiome which are the good viruses, bacteria, protozoa, and fungi that are in a symbiotic relationship with the human body.
This led to the invention of probiotic medicine which contains the good microbes and even probiotic vaccines that involve the use of a good virus to immunize you from disease.
Béchamp developed the Béchamp reduction, an inexpensive method to mass produce aniline dye, permitting William Henry Perkin to launch the synthetic-dye industry. Béchamp also synthesized the first organic arsenical drug, arsanilic acid, from which Paul Ehrlich later synthesized salvarsan, the first chemotherapeutic drug.
Bechamp spent his entire life working in a research laboratory at the Sorbonne where he made all of his groundbreaking discoveries.

Eventually genetically engineered viral vectors and mRNA were introduced which can permanently mutate a person's DNA to permanently immunize them against viral infections. Genetic engineering was invented by American scientist Donald A. Glaser in the 1970s. Glaser is a polymath that made groundbreaking discoveries in physics, chemistry, and biology, for example, he also invented the bubble chamber used in physics experiments.
Western countries are actually ahead in genetic engineering because Asian countries like Russia and China are still using immune response vaccines to treat viruses which have a low probability of immunizing people and the effect only lasts for 1 year, which necessitates the use of lifelong yearly booster shots, while the mutagenic vaccines permanently immunize people by mutating their DNA.
I personally use Vitamin D3 in combination with probiotics to strengthen my immune system so that I do not have to rely too much on antibiotics or antiviruses.
