For inclusion in the POIZ ballot package:


--Altamore 18:40, 17 August 2007 (CDT) Adjuvant: A substance (e.g. aluminum salt) that is added during production to increase the body's immune response to a vaccine. http://www.cdc.gov/vaccines/about/terms/glossary.htm#a


A component of a disease-causing agent that stimulates an immune response. More commonly, the disease which a vaccine is supposed to protect against. In the context of immunization, the latter is the meaning of interest. --Altamore 18:40, 17 August 2007 (CDT) Antigens: Foreign substances (e.g. bacteria or viruses) in the body that are capable of causing disease. The presence of antigens in the body triggers an immune response, usually the production of antibodies. http://www.cdc.gov/vaccines/about/terms/glossary.htm#a

Assessment or evaluation

The assessment or evaluation is a determination of whether vaccine doses administered to a patient are valid based on an accepted immunization schedule.


The person receiving the immunizations or having recommendations made.

Component rules

The collection of rules relating to all schedule doses in a schedule series.

Dose rules

Dose rules are the dose specific rules that validate a given immunization or control the recommendations for the next dose.


The record of the event of receiving an immunization. Sometimes referred to as a shot or a dose of vaccine. --Altamore 18:40, 17 August 2007 (CDT) Immunization: The process by which a person or animal becomes protected against a disease. This term is often used interchangeably with vaccination or inoculation. http://www.cdc.gov/vaccines/about/terms/glossary.htm#i

Immunization history

The collection of immunizations received by the client/patient.

Immunization schedule

A schedule is the collection of schedule series. In most cases, a schedule is published and supported by health jurisdictions or groups, such as the ACIP in the US.

Schedule dose

A schedule dose represents one of the expected doses in a series.

Schedule series

A series is the constellation of vaccine doses that meet the criteria to be considered protected against members of a vaccine group. More than one series may meet those goals and some series may be amended based on history. For instance, there are several series that can meet the goals of HIB. The number of doses recommended for one of these series changes, based on current age and history of vaccination.


--Altamore 18:40, 17 August 2007 (CDT)Vaccination: Injection of a killed or weakened infectious organism in order to prevent the disease. http://www.cdc.gov/vaccines/about/terms/glossary.htm#v

Vaccination forecast

The vaccine administration recommendations, based on the previous history of vaccination, patient/client age, and patient/client health conditions. These recommendations would be derived from the series selected in the schedule selected.

Vaccination history

The collection of vaccine doses actually administered to a patient.


The product that composes an immunization. --Altamore 18:40, 17 August 2007 (CDT) Vaccine: A product that produces immunity therefore protecting the body from the disease. Vaccines are administered through needle injections, by mouth and by aerosol. http://www.cdc.gov/vaccines/about/terms/glossary.htm#v

Vaccine group/vaccine family

The set of vaccines that can be administered to meet the patient's goal of being protected against a particular infectious disease or set of diseases.

[Note: I fundamentally disagree with the definition of Series (and therefore the definition of Schedule) here and continue to maintain that it is no different than group/family. (Noam Arzt)]
