Interesting and a little disturbing at the same time:
A new vaccine for swine flu is most likely to be targeted at vulnerable groups such as young children and pregnant women. But a Radio 4 documentary has discovered that little or no data exists on the safety or effectiveness of flu vaccines on these groups.

A new vaccine for swine flu is most likely to be targeted at vulnerable groups such as young children and pregnant women. But a Radio 4 documentary has discovered that little or no data exists on the safety or effectiveness of flu vaccines on these groups.
Pregnant women and children are expected to be among the groups targeted for vaccination, especially in countries likely to ration their vaccines.
Yet paradoxically the hard scientific evidence about the efficacy or dangers of these vaccines on pregnant women and young children does not exist.
"There is no study of the vaccines on pregnant women - no randomised clinical trials," said epidemiologist Tom Jefferson, who reviews influenza prevention and treatment for The Cochrane Collaboration, the voluntary global database provided by healthcare professionals which monitors the effects of healthcare worldwide.
A further problem, he explained, was that flu vaccines are unique in that they are registered and approved before full scale clinical trials have taken place.
