PG vs VG as a germicide

[Paisley]

If PG is a germicide (per the Time article about Dr. Oswald Hope Robertson's findings), is VG also a germicide?
If VG is not a germicide, what minimum percentage of PG would I need to have the germicide properties?

I've never seen anything on VG being a germicide and we really don't answer anything related to medical here. If it's important you should consult a doctor or a specialist in that field.
