High level of aluminum in mother’s hair is associated with congenital heart defects of the child.A study of the distribution of aluminum in human placental tissues based on alkaline solubilization with determination by electrothermal atomic absorption spectrometry. 2010, Kruger, Metallomics
95% of women who gave birth had aluminum found in the placenta, 81% had it in the placental membrane, 46% - in the umbilical cord. This goes to the question of vaccinating pregnant women.
