Here is the issue with Pregnancy and Adjuvents.... It is not ethically sound to just start pumping it into Pregnant females to see what happens. It is the same for many drugs out there on the market today. They are tested on Animals, but you can not be certain that if it is safe on animals it will be safe with humans, and vise versa.
Here are the classes for Drugs and Pregnancy.
Category A
Controlled studies in women do not demonstrate a risk to the fetus. The possibility of fetal harm appears remote.
Category B
Either animal studies have not demonstrated a fetal risk but there are no controlled studies in pregnant women, or animal studies have shown an adverse effect that was not confirmed in controlled studies in women.
Category C
Either studies in animals have revealed adverse effects on the fetus and there are no controlled studies in women, or studies in women and animals are not available. Drugs in category C should only be taken if the benefit justifies the fetal risk.
Category D
There is positive evidence of human fetal risk (birth defects, etc.), but the benefits from use in pregnant women may be acceptable despite the risk.
Category X
Studies in animals or human beings have demonstrated fetal abnormalities or there is evidence of fetal risk based on human experience, and the risk of the use of the drug in pregnant women clearly outweighs any possible benefit. Drugs in category x should not be taken by pregnant women for any reason.
