I hadn't heard of this term being used in epidemiology (i.e., to measure a vaccine's effectiveness). The way you phrased it doesn't make sense -- vaccines don't disinfect people (in fact, the exact opposite).
I did turn up hits that the phrase "sterilizing immunity" is in common use. However, I don't see it used in this context (with a percentage) either. A vaccine either produces sterilizing immunity, or it doesn't. It's not a population-level measure.
I'm skeptical.
