According to a recent headline from The New York Times, “the CDC isn’t publishing large portions of the COVID data it collects.” That headline downplays what the article in fact reveals:

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, several people familiar with the data said.

The article says when the Centers for Disease Control “published the first significant data on the effectiveness of boosters in adults younger than 65…it left out the numbers for a huge portion of that population: 18- to 49-year-olds, the group least likely to benefit from extra shots.”
