I don’t see the point of arguing on anything when it is the attack on someone’s credentials but not the actual information presented.
I linked to multiple websites that detailed specific problems with the actual information presented in Tatyana Obukhanych's anti-vaccination writings, including in the book you recommended.
I also acknowledged Obukhanych's credentials as an immunologist, as did the sources I linked to. Her credentials as an immunologist are not in dispute. But her claims are widely disputed, including by other immunologists.
