US recommends testing for fully vaccinated people for delta breakthrough vaccination

The examples of Israel and Iceland show that there is little hope of herd immunity. Both countries are at the forefront when it comes to high vaccination rates. But the delta variant is spreading rapidly. Your own full vaccination protects against a serious illness, but not against so-called vaccination breakthroughs, the infection of contact persons despite the vaccination.

For the first time in half a year, more than 6000 corona infections in one day were detected in Israel on Tuesday. This with the complete vaccination of almost 60 percent of the population. In Iceland, 75 percent of the population are double vaccinated. Now the country is being hit by a fourth wave, which is more powerful than the previous ones. Since mid-July, the number of new infections every day has risen from the single-digit range to more than 300.
