I wasn't a bio major but the nanoparticles are not supposed to show up in the circulatory system, hence not in the organs, IIUC. Yet the lab studies are finding the highest concentration in the ovaries for the 14-24 group.
This is incorrect. This information comes from purposely misleading websites. The distribution data is from rats, and it shows that at 1 hour after injection, 53% of the vaccine is at the injection site and 0.009% is in the ovaries. Women in the Pfizer and Moderna studies became pregnant at equal rates in the vaccine and placebo groups.
