Kinda like taking antibiotics for the slightest little infection, right? Sometimes people were given antibiotics even for a virus if they complained to the doctor that he wasn’t doing anything.
Similar, but different.
Over prescribing antibiotics and/or having patients prematurely discontinue taking antibiotics before all of the pathogens are eliminated can allow the microbes to acquire resistance to the antibiotic.
That does not effect the bodies immune system.
Administering a series of multiple vaccine shots ( the Covid “booster shots” are simply more of the same vaccine. Even the “bivalant vaccine” is the old mRNA shot with a second, new mRNA component) effectively disregualtes and degrades the bodies immune system which compromises the bodies ability to fight off not just covid virus, but many other infectious diseases as well.
Additionally, the disregualtion can result in an auto immune response where the bodies immune system attacks itself or it can compromise the bodies ability to fight cancers and other abnormalities.
