"The reality is that there hasn't been enough time to conduct mass clinical trials. Almost no drugs have been fully tested in pregnancy (which pregnant woman in their right mind would enrole in such a trial?)."The inserts refer to clinical trials conducted in the 80s and 90s. This should also raise suspicion as this strain is supposedly novel (again, from a Reuters link about the swine flu deaths in Mexico).And you're right; no sane pregnant woman would want to enroll in clinical trials in addition to the obvious ethical issues.But the big issue here is the WHO insisting that pregnant women take the vax when the inserts otherwise warn against it unless it is absolutely needed.
