CDC‑backed health survey call – should you answer? - +1 877-220-4805 ((877) 220-4805)
Summary — +18772204805
Expert Opinion
These calls claim to be a CDC‑backed health survey, asking about children and immunizations. Many recipients have heard the number linked to NORC at the University of Chicago, the research firm that administers the National Immunization survey for the agency. While the program is legitimate, the calls often come at inconvenient hours and may feel intrusive, especially when no personal data is required. To stay safe, verify the call by visiting the official CDC survey page, never share Social Security numbers or medical records, and ask for a callback number. If you prefer not to participate, request to be placed on the do‑not‑call list or block the caller through your carrier, and report persistent unwanted calls.

The number appears authentic; you can verify it on the CDC’s National Immunization Survey site (cdc.gov/vaccines/imz-managers/nis/participant/index.html) which explains calls from 312-871-4247, 312-871-4248, 312-871-4249, or 404-806-4812 (Caller ID CDC NATL IMMUN) regarding various NIS surveys conducted for the CDC by NORC at the University of Chicago.

Honestly, i dont think its a good idear to give out personal info to unknown callers, it's kinda creepy
Looks like a recorded medical‑prescription call from Honolulu, Hawaii—just a typical robo‑call, you know.

Unfortunately, our phone numbers often end up in company databases, which are then sold to marketing and telemarketing firms, resulting in unwanted calls
A survey from the CDC was the purpose of the call, aparently this has been an ongoing issue for years, i requested to be added to their do not call list, if they continue to call i reccomend contacting your phone provider to block the number.

The purpose of the survey is to gather data on immunization rates among children; however, doctors' offices would not be able to provide information about unimmunized children due to privacy concerns.
