Expert Opinion

These calls are almost certainly coming from the CDC’s National Immunization Survey, a legitimate research effort that polls households about vaccination status. While the agency is exempt from the Do‑Not‑Call rules, the timing (often after 8 PM) and repeated outreach can feel intrusive, especially for people without children. Spoofed Caller ID makes verification harder, so treat any request for personal or minor‑health data with caution. If you’re not a target demographic, you can politely decline, request removal from the list, or block the number. Survey calls must still respect the 8 AM‑9 PM window, and spoofing remains a broader telecom challenge.
