@billie.mace: Replying to @SumDudeInCAN “are vaxx safe” is a much different statement/question than “is this treatment is considered a vaxx” and have wildly different methods and thresholds to “prove true or not true”. In fairness my statement did not include the concept of intraspecific parasitism.. but that is also a whole other category, that again, is seperate from the process of growing a fetus in your uterus.
