I agree. Everyone is unique due to their genetic expression from a lifetime of immune function and response. There is limited data and close to zero statistical confidence for the human population about what constitutes effective antibody levels for immunity because antibody levels are almost never measured in vaccine recipients. For example, the chicken pox vaccine trial groups were in the low thousands of people (search and read). The levels of vaccine sub-proteins and adjuvants are almost never measured in recipients. So while disease levels have decreased, likely due to vaccines and other environmental issues, there is almost no measurable data for antibody titer levels or accumulation and immune responses to the vaccine or any other ingredients or injection sites. The HLA gene SNPs can help indicate reaction to vaccine subproteins and the immune response, or the accumulation of adjuvants like Aluminum, Mercury, etc in some people (scientific studies are starting to emerge on this). I know of three different vaccine+recipients (flu, polio, rabies) who suffered from or are still suffering from Guillane-Barre syndrome which started within days of injections. My son now has tendon flexor issues and had transient synovitis in the leg/hip near his chicken pox vaccine injection. The doctors dismiss any connection to the vaccine with zero data to back up their claim when in fact it by far the largest factor (detailed analysis of my son's leg, material accumulation, and genetic testing could shed more light).
