That is exactly what the article says (25x less likely to have a severe case/die). The point is the transmissability (as also recently published by the CDC). You yourself get a milder case if you're vaccinated and catch Delta. But you can now still transmit it to children that can't be vaccinated (and who potentially are in a risk group), friends that have a contra-indication to vaccination but are in a risk group etc.
