If a one-shot sterilization vaccine was out there, I think we would know. Many, many people would love to be permanently, nonsurgically sterilized after their one or two children.
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.
People are able to sterilize themselves today by different means. Are for compulsory sterilization?
