So, the mast cell activation by the vaccine tells me these vaccinations can induce anaphylaxis.

Not fun - in my case (not from vaxx), after my first episode 6 years ago, my health has never fully recovered. Literature says that anaphylaxis has no long term effects on overall health but I can say flat out that's a lie. The episode was brought on by soft shell crab but has evolved into idiopathic anaphylaxis which basically means that at any time for any reason or really for no reason, I can have an episode. It has been hell on my life and my family's lives. If the vaxx induces idiopathic anaphylaxis, in my opinion, the people responsible should either have lifelong jail sentences or the death penalty.
