COVID-19 Vaccine Breakthrough Cases Increased
As of June 1, 2021, the CDC received reports from 47 U.S. states and territories of 3,016 patients with COVID-19 vaccine Breakthrough infections who were hospitalized or died.
And about 79% of the Breakthrough Cases were seniors (65 yr).
In total, there have been 2,854 hospitalized or 535 fatal cases confirmed. The CDC reported 16% of 535 fatal cases were reported as asymptomatic or not related to COVID-19.
As of May 1, 2021, the CDC transitioned from monitoring all reported vaccine Breakthrough Cases to identify and investigate only hospitalized or fatal cases due to any cause. This shift maximizes the quality of the data collected on cases of greatest clinical and public health importance.
Previous data on all vaccine Breakthrough Cases reported to CDC from January–April 2021 are available at this CDC link.
CDC developed a national COVID-19 vaccine breakthrough REDCap database where designated state health department investigators can enter, store, and manage data for cases in their jurisdiction. State health departments have full access to data for cases reported from their jurisdiction. Ultimately, CDC will use the National Notifiable Diseases Surveillance System to identify vaccine breakthrough cases.
