Jessica Rose just published this fascinating and very important Stack today: It makes for fascinating, if somewhat disturbing reading. Rather than highlight what Jessica is saying, which I strongly suggest you read, I went through the actual study myself, which she cites, and there’s a few points of my own which I’d like to highlight, arising from the findings of that study, which I think are vitally important to get across, because they
Does this have implications for pregnant women who have been boosted? According to the wikipedai page on IgG:
"IgG is secreted as a monomer that is small in size allowing it to easily perfuse tissues. It is the only antibody isotype that has receptors to facilitate passage through the human placenta, thereby providing protection to the fetus in utero. Along with IgA secreted in the breast milk, residual IgG absorbed through the placenta provides the neonate with humoral immunity before its own immune system develops. Colostrum contains a high percentage of IgG...
Therefore, in the first six months of life, the newborn has the same antibodies as the mother and the child can defend itself against all the pathogens that the mother encountered in her life (even if only through vaccination) until these antibodies are degraded. This repertoire of immunoglobulins is crucial for the newborns who are very sensitive to infections, especially within the respiratory and digestive systems.
It makes a person wonder what this looks like in people that have had two doses, two boosters, the bi-valent booster, and one or more breakthrough infections.
