At what point do you say to yourself these f were willing to vaccinate children with mind control nanoparticles regardless of the oxidative stress side effects?

Willing to? You mean have been. The symptoms of autism amount to oxidation stress in the brain. https://pubmed.ncbi.nlm.ni...

It was found that semiconductor quantum dots produce free radicals upon UV irradiation in aqueous solution with two independent methods

Oxidative stress is an imbalance between free radicals and antioxidants in your body.

Oxygen radicals and nitric oxide (NO) are generated in excess in a diverse array of microbial infections. Emerging concepts in free radical biology are now shedding light on the pathogenesis of various diseases. Free-radical induced pathogenicity in virus infections is of great importance, because evidence suggests that NO and oxygen radicals such as superoxide are key molecules in the pathogenesis of various infectious diseases.

It is becoming increasingly apparent that certain types of inflammatory tissue injury are mediated by reactive oxygen metabolites. The most likely sources of these oxidizing agents are the phagocytic leukocytes (e.g., neutrophils, monocytes, macrophages, and eosinophils) that invade the tissue. These reactive radicals and oxidants may injure cells and tissue directly via oxidative degradation of essential cellular components as well as injure cells indirectly by altering the protease/ antiprotease balance that normally exists within the tissue interstitium. It is becoming increasingly apparent that in addition to promoting cytotoxicity, reactive oxygen metabolites may also initiate and/or amplify inflammation via the upregulation of several different genes involved in the inflammatory response, such as those that code for proinflammatory cytokines and adhesion molecules.

This may occur by the activation of certain transcription factors, such as nuclear transcription factor kB (NF-kB). NF-kB is a ubiquitous transcription factor and pleiotropic regulator of numerous genes involved in the immune and inflammatory response. Essential nutrients such as vitamins C and E may protect against oxidant-mediated inflammation and tissue damage by virtue of their ability to scavenge free radicals and by their ability to inhibit the activation of NF-kB (and possibly other oxidant-sensitive transcription factors). Thus, maintaining adequate antioxidant status may provide a useful approach in attenuating the cellular injury and dysfunction observed in some inflammatory disorders.

If viruses at one end of the spectrum compared to say nanoparticles at the other end of the spectrum both cause free radicals, ROS, inflammation and oxidative stress... what harm will vaccines cause?
