While I’m definitely not suggesting anyone go against the recommend interval of every ten years, as how long the protection lasts in any one person is variable and there are other pathogens it protects against too, most in the US have had six vaccinations against it by the time they are an adult. In some cases especially after six or more doses and in adults, protection can potentially persist longer then ten years, sometimes decades, giving people like the commenter you’re replying to who may skip a dose the false impression that they didn’t need a vaccine in the first place. But again, do not deviate from the every ten year schedule for lots of good reasons. It’s a quick and easy way to ensure you do not have a very horrific and life changing experience after a minor scrape.
