Missouri has reported just 14 breakthrough COVID-19 cases among people who are fully vaccinated to federal health officials, even though dozens more have been detected in just the state’s largest county.
The St. Louis Post-Dispatch reports that the U.S. Centers for Disease Control and Prevention asked states at the start of this month to instruct local health departments and health systems to collect real-time information on “breakthrough infections.” States are to collect the data and enter it into a national database.
But by mid April, when the CDC announced its first tally of breakthrough infections, it caught a disease investigator for the St. Louis County Department of Public Health by surprise.
