The agency has withheld critical data on boosters, hospitalizations and, until recently, wastewater analyses.
Two full years into the pandemic, the agency leading the country’s response to the public health emergency has published only a tiny fraction of the data it has collected---
Kristen Nordlund, a spokeswoman for the C.D.C., said the agency has been slow to release the different streams of data “because basically, at the end of the day, it’s not yet ready for prime time.” She said the agency’s “priority when gathering any data is to ensure that it’s accurate and actionable.”
Another reason is fear that the information might be misinterpreted, Ms. Nordlund said.
