I just have to tell you how much I LOVE the VIIS system. I’m going through my tickler file of children late for immunizations and am using VIIS before I send out letters. EVERY CHILD I’ve checked has gotten immunizations elsewhere. YEAH!!!!!!

Kim Carlton BSN, RN,BC King William Health Department

The earliest date to vaccinate is a great tool. I love that VIIS lets you know if a vaccine is invalid and it guides you through the process of entering vaccines.

Connie Blanks, RN Altavista Medical Center

When we are reviewing immunization records at the start of the year for students new to the county it is great to see if they are there instead of calling parents or doctor offices! It is also great to see at the end of the school year for the 5th graders to see if they have a TDAP. IT (VIIS) saves a gigantic amount of time!

Sara Tomlin, School Nurse Nelson County Public Schools

Fairfax County and Alexandria Health Departments have recognized and given ALL Pediatrics awards this year for the significant importance we have contributed to our communities through our use, support, and diligence with encouraging other offices on the benefits of VIIS. The Health Departments also commended our practice on making it easier for them to locate so many records, as a high percentage has been entered into the system by our practice. Even with an EMR, the practice utilizes VIIS as our primary immunization record for all our patients.

Sheryl Davis, RN All Pediatrics

I have been in nursing for more than 30 years and have never used a tool like VIIS (the Virginia Immunization Information System). VIIS is the best thing ever invented and everyone in the state should be using it. It has saved me so much time. I do not have to call the providers or the local health departments as much for shot records. Most of my patients are in VIIS with a partial or full record.


Niki Hooper, RN All Pediatrics

VIIS is the best information system for health care providers to obtain proof of immunization. Once you are trained, one wondered why it took us so long to use the new tool.
