The unvax'ed make up a proportionally smaller % of the cases during the summer spike in Israel.
This is almost certainly because most people in Israel are vaccinated and the country is pretty strong with its public safety measures.
EDIT: Just read up more on this, and it's also because of waning vaccine immunity over time coinciding with the emergence of Delta -- which isn't surprising and doesn't change the fact that unvaccinated people who've never been infected are more likely to transmit the virus than vaccinated people people whose vaccines haven't waned too heavily. (But this is why we've authorized boosters for people over the age of 60.)
As more people get vaccinated, we'll see what appears to be higher transmission rates among vaccinated people. This happened here in a highly vaxxed county in MA or something. But this isn't because vaccinated people are more likely to spread the virus -- literally all controlled, peer-reviewed scientific studies on the matter refute that. It's simply because in some places the unvaxxed minority has shrank to the point that most spread is happening among vaccinated people.
This is a great thing, btw. In places where more spread is happening among vaccinated people, far fewer people will get sick and be hospitalized, and transmission is easier to control because it's happening at a slower rate. It also means those places are close to actually reaching what "herd immunity" will look like with COVID. (The virus will persist and spread, but it will be relatively harmless because it will no longer be new to most people's immune systems.)
I mean, just check out state-by-state test positivity rates and compare that with the states with the lowest vaccination rates.

Here are the states with the lowest vaccination rates and their test-positivity rankings:
1. Idaho (46% vaccination rate)
49.4% test positivity rate (worst in country)
2. Wyoming (47%)
15.9% (9th worst)
3. West Virginia (48%)
10.4% (24th worst)
4. Mississippi (49%)
12.4% (19th worst)
5. North Dakota (49%)
15% (12th worst)
You only really need to glance at the test-positivity rankings to see that most states on the top half of the list are likely to be states where fewer people are vaccinated.
If vaccinated people were more likely to spread the virus, then the two lists wouldn't match up so nicely.
