California has announced that the percentage of vaccine breakthrough infections in fully-vaccinated residents is rising. In June 2021 it was 20%, and has so far doubled every month.

In March 2021, vaccinated people accounted for only 2% of all infections. In April, that rose to 5%. In May, it was 11%.  The rise coincides with the rise of the more transmissible Delta variant in the county, which now accounts for 84% of all variants recently identified

“The Delta variant is a game-changer,” said Los Angeles County Public Health Director Barbara Ferrer said on Thursday. report
