Israel study shows that previous infection provides higher immunity. I haven't seen any other studies showing the opposite but not many of them are done. Most studies compare previously infected unvaccinated with previously infected vaccinated to show that vaccine provides additional immunity. The second is fast developing situation therefore not many studies are done. I had statistics from hospital admittance in Latvia. It was interesting to see that about 13% of deaths are in vaccinated and 30% of hospitalized were vaccinated too. At this time Latvia had about 60% vaccinated almost the same in all age groups. It shows that vaccine has some effectiveness but vaccinated still spread infection considerably. The main benefit is that it reduces risk of death about 10 times but risk reduction in getting infected or sick is not that good.
