I try to remember these immunoglobulin functions by the third letter. IgG being the 'generals' that hang around long term and have experience from past battles ( IgGs are produced at the later stages of the infection and remain in the body to fight against repeated infections.) IgM is the 'military' that goes in to fight first (the first responders to an infection ). IgE is allergeeeees. Immunoglobulin G (IgG) can be further divided in four subclasses, named, in order of decreasing abundance IgG1, IgG2, IgG3, and IgG4 What I get from the article is that IgG4 which is supposed to be the smallest amount, takes over binding to the antigens and crowds out the 'good' IgG1 from the job of fighting cancer. IgG1 is involved in tumor control or suppression but can't do it's job due to too much IgG4. IgG4 sucks at the tumor control job, so cancer has a chance to win. Constant mRNA covid vaccines means continuous antigen stimulation and production of too much IgG4, and greater chance of cancer relapse or onset. Bottom line: Don't take the shot, you'll kill yourself.
