    That’s what effectiveness means, since removing dental plaque isn’t a binary thing. If you’re trying to remove plaque, then a percentage reduction is a corresponding increase in effectiveness. If a vaccine has a 20% reduction in disease compared to another vaccine, it’s 20% more effective. I’m pretty sure this comment isn’t just splitting hairs; it’s actually wrong in its pedantry.
