Probably because those 15% of people are driving 50% or more of the spread. One of the reasons Delta is such a big deal is that it raised the herd immunity threshold from around 70% to around 95% (of 2 dose MRNA based, J&J wouldn't be strong enough to provide herd immunity if 100% of people had it).
