“vaccine isn’t working on variant delta in highly vaccinated Israel“

From your link “ Israel has detected about 40 percent to 50 percent of new cases in the vaccinated population, although, he added that the symptoms of the otherwise sometimes severe infection were mostly mild.”

While some of the vaccinated are getting COVID, the cases are mostly mild. That says the vaccine is helping. Also note that while 40-50% of new cases are in people who are vaccinated, Israel has 57.9% of its population vaccinated, 81% of those over 16. Given those stats, if the vaccination was ineffective one would expect a higher percentage of cases among the vaccinated.
