Well, I Googled for it (not that Google is the most honest search engine in the world for all topics) and there appear to be fears that a tetanus vaccine might double in that capacity.
Here’s where we need to say we need more information. It would be a relief if not true.
I’ve had tetanus vaccines, and I have ten healthy children. It’s possible that a contraceptive element is being added (I might have read that ...), but there’s no indication in the developed world of a safe, permanent, contraceptive shot, and the demand for it would be immense.
You know what, on second thought, anyone who believes this tripe,,, next time you step on a rusty nail. I think you should avoid the tetanus shot. I hear it’s secret birth control.
Same with the polio vaccine. Id totally skip it if I were you. Then go swim in stagnant water. Yep, that’s just what I think you should do.
Don’t listen to that nutty Dr. Salk.
