Between Jan. 1 and April 28, California public health officials recorded 3,084 breakthrough cases of COVID-19 in people who were fully vaccinated. That’s out of 12.9 million people who were fully vaccinated.
“As more time passes and more people are fully vaccinated, it is likely that additional post-vaccination cases will occur,” the California Department of Public Health said in a statement. “The number of post-vaccination cases remains small.”
The California Department of Public Health said it’s trying to find COVID-19 cases among vaccinated people by reviewing case and vaccine records.
