The agency in court papers said that on or before Sept. 30, it would post on its website a “public use” set of data from about 10 million people who signed up for its “v-safe” program — a smartphone-based system that periodically sends people text messages and web surveys to monitor potential side effects from the Pfizer, Moderna and Johnson & Johnson Covid-19 vaccines.

But the CDC missed its deadline. A spokesperson cited a delay in “the technical and administrative processes” necessary to post on the agency’s website, but said it hopes to have the information up by late November or early December.

In the meantime, the CDC handed over the v-safe data (minus personal identifying information) to the plaintiff in the FOIA case, the Informed Consent Action Network, or ICAN, a Texas-based nonprofit that says it opposes “medical coercion” in favor of individual healthcare choices.
