Not sure why the posts asking for vaccine risks are getting downvoted. Pandemrix, the vaccine for swine flu, caused a notable amount of narcolepsy cases in recipients here in FIN (notable here meaning the amount of yearly cases spiked by 3-4x) and as with anything that's taken quick to market there has to be some risk of overlooking some tail events somewhere. It's not an anti-vaccine attitude, just healthy skepticis…
I think a comment on HN from about a week or so maybe?
