I learned as a small child that you could only get tetanus from a puncture wound that had not bled much. That bleeding a fair amount washed out a wound. When I got a deeo puncture on my foot from being a happy little heathen running around barefoot on the island I lived on, I got a tetanus shot and not one bit of reaction to it. That was many decades ago. I believe they have changed the formulation of the shot into yet another way to endanger health. Dirty rotten stinking Big Pharma bastards. So yeah... I mistrust vaccines now for anything
