The researchers concluded that overall, while the man’s excessive vaccination history increased his antibody levels and apparently protected him from infection, hyper-activating his immune system did not seem to have a negative effect on his ability to mount an adequate response. At the same time, his extreme measures did not seem to afford him a level of super-immunity that distinguished his response dramatically from others who followed the recommended vaccination schedule. “His immune system was neither positively nor negatively affected," says Schober.
