CDC survey. DO NOT CALL!! None of your business
Call went to voice mail, asked me to call back. I did not. I have since gotten two there calls form different numbers asking for vaccine history and if and how many kids I have. The last tow came up as CDC on caller ID.
Calls about CDC immunizations and if there are children from 12 month to 4 yrs old in household.
Robocall from University of Chicago with B.S. about immunizations. Keep calling, very annoying.
wanting to know if we had children in the house
Mentioned in a robocall for a literal CDC survey. It's a toll-free number, and it's listed on the CDC website, so I'm sure it's safe.
