The study above does not answer these questions and indeed proposes that further research should consider related questions about the effects of the Sarscov2 vaccine, but I am curious more about IgG4 aside from the above study–is it better to have a higher prevalence of IgG3 and IgG1 for defending against viruses? What would happen if there were a higher prevalence of IgG4 from a theoretical medical perspective? What would the effects on defending against viruses be?

This really helped to explain the various antibodies and their role with our immune system. Goes further into IgG4 and covid. It’s concerning and definitely an issue to watch out for.
