COVID-19 Breakthrough Case Investigations and Reporting
"CDC is transitioning to reporting ONLY patients with COVID-19 vaccine breakthrough infection that were hospitalized or died to help maximize the quality of the data collected on cases of greatest clinical and public health importance. That change in reporting will begin on May 14, 2021. In preparation for that transition, the number of reported breakthrough cases will not be updated on May 7, 2021."

No transparency for you from the CDC going forward. Looks like they are simply not prepared to handle factually reporting on all the data that they are receiving (allegedly).
