catski, about the animal tests with Pandemrix:
The European Medicines Agency has a detailed PDF about Pandremix which includes information about clinical trials. See sections 4.6 and 5.3 in this document I've copied them here for convenience.
4.6 Pregnancy and lactation
There are currently no data available on the use of Pandemrix in pregnancy. Data from pregnant women vaccinated with different inactivated non-adjuvanted seasonal vaccines do not suggest malformations or fetal or neonatal toxicity.
Animal studies with Pandemrix do not indicate reproductive toxicity (see section 5.3).
The use of Pandemrix may be considered during pregnancy if this is thought to be necessary, taking into account official recommendations.
Pandemrix may be used in lactacting women.
5.3 Preclinical safety data
Non-clinical data obtained with the mock-up vaccine using a H5N1 vaccine strain reveal no special hazard for humans based on conventional studies of safety pharmacology, acute and repeated dose toxicity, local tolerance, female fertility, embryo-fetal and postnatal toxicity (up to the end of the
lactation period).
