It was about 150 cases in Sweden registered this far compared to estimates of about less than a dozen lives saved (to be fair, some estimates claim 40-60 lives saved over two years; it depends on the mortality rates in the non-vaccinating countries you compare with).
We can argue the definition of 'many' as in many saved or many hurt in this case, the incidence of either is small compared to the numbers vaccinated. Which is really the whole problem; when the mortality rates are as low as with the swine flu, even a low incidence of nasty side effects will tip the balance from vaccination being a great idea to doing more harm than good. Weigh in the economic cost of the program and the possible lives that could have been saved with other use of the resources and you end up deep in the red.
Either way the point I'm making is that while vaccinations are often a good idea it's not as clear cut as to say they're always the right choice. Further, without the ability to make epidemiological studies on control groups it's not easy to catch rare effects like this (which in this case really stood out as the incidence was ten times the normal and there were huge immediate control groups available). Dismissing concerns out of hand increases both the risk that more untested vaccines will be deployed with insufficient care and the risk that rare effects that are visible only on aggregated data will be missed.
