Some good news ...
The CDC had inferred from the Cape Cod outbreak that breakthrough cases could transmit the Delta virus as much as infected unvaccinated people. This was apparently based on the observation that breakthrough cases had big viral loads in their noses and upper respiratory tracts. But apparently Israeli researches have found that, despite the big viral loads, breakthrough cases aren't very infectious: only 10% infect 1 person.
That would strengthen the argument that vaccination helps to reduce the spread of Covid.
