This is not immunobridging. The meaning of the IgG4 class switching is unclear and there are compelling arguments for why it could be a net positive. It is clear both the mRNA vaccines and Novavax's are protective.

I contend they are using the methodology chosen by the mRNA companies to represent themselves in VRBPAC and ACIP. And it’s not the only data they use or present. Since Novavax doesn’t induce IgG4 switch and induces a different immune response from mRNA; appears comparable but not the whole story

Chinese researchers have identified overlapping but distinct clinicopathologic features of immunoglobulin 4-related ophthalmic disease (#IgG4ROD), a form of IgG4-related disease (#IgG4RD), and #CastlemanDisease (CD). Report in the Indian Journal of Ophthalmology

Differences Observed in Clinical Features of IgG4-ROD and Castleman Disease
Both IgG4-ROD and Castleman disease may present as orbital masses or lacrimal gland enlargement, but they differ in imaging and histologic markers.
