I know 4 people who got the clot shot, and 3 of them had what might be called minor complaints (pain in arm for a week, flu like reaction, exhausted and unable to work for a few days). The 4th hasn't commented on their reaction, so maybe they had no reaction, or maybe they just haven't discussed it.

'Bad reaction' is a debatable term, but the figure for minor reactions is way higher than 1 in 500. In my admittedly small circle it's at least 3 in 4.

Also, there's also the issue of ADE. Short term reactions to the clot shot aren't the only thing to be concerned about. There's also the long term damage it causes to the immune system.
