I was curious, so I went to Israel's Ministry of Health's website today to get the latest Covid-19 statistics. What I found is the following data for those aged 12 and older.
Population eligible to be Vaccinated ~ 7,116,640 (only vaccinating those 12 and older)
Total Partially Vaccinated = 5,807,758
Total Fully Vaccinated = 5,394,642
Unvaccinated ~ 1,308,882 (takes into consideration those under 12 can not be vaccinated)
Total Active Cases = 22,103
Active Cases - Unvaccinated = 5,611
Active Cases - Fully Vaccinated = 15,988
Active Case - Partially Vaccinated = 504
% of Unvaccinated with an active case ~ 0.429%
% of Fully Vaccinated with an active case = 0.296%
% of Partially Vaccinated with an active case = 0.009%
Total Severe Cases = 362
Severe Cases - Unvaccinated = 126
Severe Cases - Fully Vaccinated = 229
Severe Cases - Partially Vaccinated = 7
% of Unvaccinated with a Severe Case ~ 0.0096%
% of Fully Vaccinated with a Severe Case= 0.0042%
% of Partially Vaccinated with Severe Case = 0.0001%
My conclusion from looking at the current Covid infection numbers from Israel? The vaccines are working to limit the number of people with a Covid case and are working to limit severe cases of Covid. In fact, you are twice as likely to have a severe case of Covid if you are unvaccinated, compared to being fully vaccinated.
