Note: Modeling and terming for vaccines that have variable composition (e.g. influenza that may be specific to a year or hemisphere) will be addressed at a future date when use cases and requirements are better understood.

    • There is no technical limit on the number of Has active ingredient attributes that may be added to a concept; a practical limit may be imposed at a later date.

For content in the International Release, this attribute value should represent either the organism antigen, or the organism antigen(s), including modifications or subtypes, that are contained in a manufactured product.

Terming Guidelines

FSN

Use the following pattern for the FSN;  align terming and case sensitivity with align terming and case sensitivity with the PT for the concept that is selected as the attribute value for the 127489000 |Has active ingredient (attribute)|. For multiple ingredient vaccine products, the active ingredients must be listed in alphabetical order, separated by the word "and", and the word "antigen" will be omitted. For concepts where all active ingredients are virus, the word "virus" may be omitted and added before "antigens".

    • Vaccine product containing only <Active ingredient PT> (medicinal product)
    • Vaccine product containing only <Active ingredient PT> and <Active ingredient PT> antigens (medicinal product)
    • Vaccine product containing only <Active ingredient PT> and <Active ingredient PT> and <Active ingredient PT> antigens (medicinal product)

For example,

      • Vaccine product containing only Hepatitis B virus antigen (medicinal product)
      • Vaccine product containing only Hepatitis A and Hepatitis B virus antigens (medicinal product)
      • Vaccine product containing only Bordetella pertussis and Clostridium tetani and Corynebacterium diphtheriae antigens (medicinal product)

|Has product characteristic| and |Has ingredient characteristic| attribute values should be added as appropriate.

Example of |Has product characteristic (attribute)|:

      • Adult vaccine product containing only Hepatitis A virus antigen (medicinal product)
      • Pediatric vaccine product containing only Hepatitis A virus antigen (medicinal product)
      • Adult vaccine product containing only acellular Bordetella pertussis and Clostridium tetani toxoid and Corynebacterium diphtheriae toxoid antigens (medicinal product)

Example of |Has ingredient characteristic (attribute):

      • Vaccine product containing only Clostridium tetani and low dose Corynebacterium diphtheriae antigens (medicinal product)
      • Vaccine product containing only Clostridium tetani and low dose Corynebacterium diphtheriae and inactivated Human poliovirus antigens (medicinal product)

Preferred Term

Use the following pattern for the PT;  align terming and case significance with align terming and case significance with the PT for the concept that is selected as the attribute value for the 127489000 |Has active ingredient (attribute)|. For multiple ingredient vaccine products, the active ingredients must be listed in alphabetical order, separated by the word "and", and the word "antigen" will be omitted. For concepts where all active ingredients are virus, the word "virus" may be omitted and added before "antigens".

  • <Active ingredient PT> only vaccine product
  • <Active ingredient PT> and <Active ingredient PT> antigen only vaccine product
  • <Active ingredient PT> and <Active ingredient PT> and <Active ingredient PT> antigen only vaccine product

For example,

      • Hepatitis B virus antigen only vaccine product
      • Hepatitis A and Hepatitis B virus antigens only vaccine product
      • Bordetella pertussis and Clostridium tetani and Corynebacterium diphtheriae antigens only vaccine product

|Has product characteristic| and |Has ingredient characteristic| attribute values should be added as appropriate.

Example of |Has product characteristic (attribute)|:

      • Hepatitis A virus antigen only adult vaccine product
      • Hepatitis A virus antigen only pediatric vaccine product
      • Adult acellular Bordetella pertussis and Clostridium tetani toxoid and Corynebacterium diphtheriae toxoid antigens only vaccine product

Example of |Has ingredient characteristic (attribute):

      • Clostridium tetani and low dose Corynebacterium diphtheriae antigens only vaccine product
      • Clostridium tetani and low dose Corynebacterium diphtheriae and inactivated Human poliovirus antigens only vaccine product

Synonyms

Synonyms matching the FSN are not required.

Synonyms corresponding to the disorder that is the target of the vaccine are allowed. For multiple ingredient vaccine products, the disorders must be listed in alphabetical order and separated by the word "and". Note that these are not true synonyms; they may be updated and identified as "near-synonym" descriptions when that functionality becomes available.

For example,

      • Hepatitis B vaccine
      • Hepatitis A and Hepatitis B vaccine
      • Diphtheria and pertussis and tetanus vaccine

|Has product characteristic| and |Has ingredient characteristic| attribute values should be added as appropriate.

Example of |Has product characteristic (attribute)|:

      • Hepatitis A adult vaccine
      • Hepatitis A pediatric vaccine
      • Diphtheria toxoid and acellular pertussis and tetanus toxoid adult vaccine

Example of |Has ingredient characteristic (attribute):

      • Low dose diphtheria and tetanus vaccine
      • Low dose diphtheria and inactivated poliomyelitis and tetanus vaccine

Synonyms representing abbreviations for product (e.g. MMR, DTaP) will not be included in the International Release due to lack of internationally accepted reference source.
