            COMMISSION IMPLEMENTING DECISION (EU) 2021/2014
of 17 November 2021
         
amending Implementing Decision (EU) 2021/1073 laying down technical specifications and rules for the implementation of the trust framework for the EU Digital COVID Certificate established by Regulation (EU) 2021/953 of the European Parliament and of the Council
(Text with EEA relevance)


THE EUROPEAN COMMISSION,

Having regard to the Treaty on the Functioning of the European Union,


Having regard to Regulation (EU) 2021/953 of the European Parliament and of the Council of 14 June 2021 on a framework for the issuance, verification and acceptance of interoperable COVID-19 vaccination, test and recovery certificates (EU Digital COVID Certificate) to facilitate free movement during the COVID-19 pandemic (1), and in particular Article 9(1) and (3) thereof,

Whereas:







(1)


Regulation (EU) 2021/953 sets out the EU Digital COVID Certificate the purpose of which is to serve as a proof that a person has received a COVID-19 vaccine, a negative test result or has recovered from infection for the purpose of facilitating the holders’ exercise of their right to free movement during the COVID-19 pandemic.












(2)


In order for the EU Digital COVID Certificate to be operational throughout the Union, the Commission adopted Commission Implementing Decision (EU) 2021/1073 (2), laying down technical specifications and rules to populate, securely issue and verify EU Digital COVID Certificates, ensure the protection of personal data, lay down the common structure of the unique certificate identifier and issue a valid, secure and interoperable barcode.












(3)


Many Member States have already announced or have already started to administer COVID-19 vaccine doses additional to the standard primary vaccination series, that is, the vaccination series intended to provide sufficient protection at an initial stage, notably to persons who may not have responded adequately to the primary vaccination series, and are considering ‘booster’ doses for people who responded adequately to primary vaccination. In this context, the European Centre for Disease Prevention and Control published, on 1 September 2021, interim public health considerations for the provision of additional COVID-19 vaccine doses (3).












(4)


On 4 October 2021, the European Medicines Agency’s Committee for Medicinal Products for Human Use concluded that an extra dose of the COVID-19 vaccines Comirnaty and Spikevax may be given to people with severely weakened immune systems, at least 28 days after their second dose (4). The Committee also evaluated data for Comirnaty showing a rise in antibody levels when a booster dose is given approximately 6 months after the second dose in people from 18 to 55 years old. On the basis of this data, the Committee concluded that booster doses for Comirnaty may be considered at least 6 months after the second dose for people aged 18 years and older. As stated by the European Medicines Agency, public health bodies at national level may issue official recommendations on the use of booster doses, taking into account emerging effectiveness data and the limited safety data. The product information of Comirnaty (5) and Spikevax (6) have been updated accordingly to include these recommendations.












(5)


To avoid diverging, confusing or technically incompatible approaches among Member States, it is necessary to adopt uniform rules as to populating vaccination certificates referred to in point (a) of Article 3(1) of Regulation (EU) 2021/953 issued following the administration of such additional doses.












(6)


According to Article 5 of Regulation (EU) 2021/953, a vaccination certificate is to be issued after the administration of each dose, it is to clearly indicate whether or not the vaccination course has been completed, and it is to contain the number of doses administered to the holder. Pursuant to the Annex to that Regulation, a vaccination certificate is to include, as data fields, the number in a series of doses as well as the overall number of doses in the series. Any rules as to how to populate vaccination certificates issued following the administration of additional doses, adopted by means of an implementing act, are to comply with the requirements established by Regulation (EU) 2021/953.












(7)


Vaccine certificates issued for doses of the primary vaccination series should indicate full vaccination after the completion of the standard primary series even in cases where the later administration of additional doses is recommended. Vaccine certificates issued for additional doses administered after the standard primary vaccination series should indicate the number of doses administered to the holder, as provided for in point (b) of Article 5(2) of Regulation (EU) 2021/953, as well as the overall number of doses within the series, counting the primary vaccination doses as well as any additional doses.












(8)


Particular attention should be paid to the situation of vulnerable groups who may receive additional doses as a matter of priority. If a Member State decides to administer additional doses only to specific sub-groups of the population, it could consider issuing vaccination certificates indicating the administration of such additional doses only upon request and not automatically, given that Article 5(1) of Regulation (EU) 2021/953 offers Member States the possibility to choose between these two options. As long as additional doses are administered only to a specific sub-group of the population, persons belonging to that sub-group should not be required to produce the certificate indicating the administration of an additional dose when exercising their right to free movement during the COVID-19 pandemic, and could instead make use of the certificate received following the completing of the primary vaccination series.












(9)


At the same time, it is important that vaccination certificates issued to persons belonging to such groups following the administration of additional doses also correctly reflect the number of doses administered to them. Firstly, Regulation (EU) 2021/953 gives all persons a right to receive a vaccination certificate, indicating the number of doses administered to them, after the administration of each dose. Secondly, Member States may eventually limit the duration of acceptance, for the purposes of free movement, of vaccination certificates issued following the completion of the primary vaccination series, if scientific evidence becomes available that the protection afforded by the primary vaccination series wanes below a certain level after a certain period. Not giving vulnerable groups the opportunity to obtain vaccination certificates following the administration of an additional dose would require further administrative steps to obtain them when they become more important for their freedom of movement, and could thus result in obstacles thereto.












(10)


In addition, the rules for populating the EU Digital COVID Certificate should be further clarified. Specific value sets applying the established coding rules should be made publicly available.












(11)


To ensure the interoperability of the EU Digital COVID Certificate, a common coordinated data structure for the data to be included in certificates referred to in Article 3(1) of Regulation (EU) 2021/953 should be defined through the use of a JavaScript Object Notation (JSON) schema.












(12)


Implementing Decision (EU) 2021/1073 should therefore be amended accordingly.












(13)


The European Data Protection Supervisor was consulted in accordance with Article 42(1) of Regulation (EU) 2018/1725 of the European Parliament and of the Council (7) and delivered formal comments on 18 October 2021 (8).












(14)


In the light of the need for rapid implementation of the amended technical specifications for the EU Digital COVID Certificate, this Decision should enter into force on the day of its publication in the Official Journal of the European Union.












(15)


The measures provided for in this Decision are in accordance with the opinion of the Committee established by Article 14 of Regulation (EU) 2021/953,





HAS ADOPTED THIS DECISION:



Article 1
Implementing Decision (EU) 2021/1073 is amended as follows:

ANNEX I



‘ANNEX II

RULES FOR THE PURPOSE OF POPULATING THE EU DIGITAL COVID CERTIFICATE

The general rules concerning the value sets established in this Annex aim to ensure interoperability on semantic level and shall allow uniform technical implementations for the EU Digital COVID Certificate. Elements contained in this Annex may be used for the three different settings (vaccination/testing/recovery), as provided for in Regulation (EU) 2021/953. Only elements with the necessity of semantic standardisation through coded value sets are listed in this Annex.
Translation of the coded elements into the national language are under the responsibility of the Member States.
For all data fields not mentioned in the following value set descriptions, encoding is described in Annex V.
If for any reason the preferred code systems listed below cannot be used, other international code systems may be used and advice on how to map the codes from the other code system to the preferred code system shall be put in place. Text (display names) may be used in exceptional cases as a backup mechanism when a suitable code is not available in the defined value sets.
Member States using other coding in their systems shall map such codes to the described value sets. Member States are responsible for any such mappings.
As some value sets based on the coding systems provided for in this Annex, such as those for vaccine and rapid antigen test coding, are changing often, they shall be published and regularly updated by the Commission with the support of the eHealth Network and the Health Security Committee. The updated value sets shall be published on the relevant website of the Commission, as well as on the webpage of the eHealth Network. A history of changes shall be provided.
1.   Disease or agent targeted/Disease or agent from which the holder has recovered: COVID-19 (SARS-CoV-2 or one of its variants)

To be used in certificate 1, 2 and 3.
The following code shall be used:











Code

2.16.840.1.113883.6.96


2021-01-31




2.   COVID-19 vaccine or prophylaxis

Preferred Code System: SNOMED CT or ATC Classification.
To be used in certificate 1.
Examples of codes that shall be used from the preferred code systems are the SNOMED CT code 1119305005 (SARS-CoV-2 antigen vaccine), 1119349007 (SARS-CoV-2 mRNA vaccine) or J07BX03 (covid-19 vaccines).
A value set setting out the codes to be used pursuant to the code systems established in this section shall be published and regularly updated by the Commission with the support of the eHealth Network. The value set shall be extended when new vaccine types are developed and put into use.
3.   COVID-19 vaccine medicinal product

Preferred Code Systems (in the order of preference):






—


Union Register of medicinal products for vaccines with EU-wide authorisation (authorisation numbers);










—


A global vaccine register such as one that could be established by the World Health Organisation;










—


Name of the vaccine medicinal product in other cases. If the name includes whitespaces, these shall be replaced by a hyphen (-).




Name of the Value Set: Vaccine.
To be used in certificate 1.
An example of a code that shall be used from the preferred code systems is EU/1/20/1528 (Comirnaty). An example of the name of the vaccine to be used as a code: Sputnik-V (standing for Sputnik V).
A value set setting out the codes to be used pursuant to the code systems established in this section shall be published and regularly updated by the Commission with the support of the eHealth Network.
Vaccines shall be coded using an existing code in the published value set, even if their names are different in different countries. The reason is that there is no global vaccine registry covering all vaccines in current use yet. Example:






—


For the vaccine “COVID-19 Vaccine Moderna Intramuscular Injection”, which is the name of the Spikevax vaccine in Japan, use code EU/1/20/1507, as it is the name of this vaccine in the EU.




If this is not possible or advisable in a specific case, a separate code will be provided in the published value set.
4.   COVID-19 vaccine marketing authorisation holder or manufacturer

Preferred Code System:






—


Organisation code from EMA (SPOR system for ISO IDMP);










—


A global vaccine marketing authorisation holder or manufacturer register, such as one that could be established by the World Health Organisation;










—


Name of the organisation in other cases. If the name includes whitespaces, these shall be replaced by a hyphen (-).




To be used in certificate 1.
An example of a code that shall be used from the preferred code system is ORG-100001699 (AstraZeneca AB). An example of the name of the organisation to be used as a code: Sinovac-Biotech (standing for Sinovac Biotech).
A value set setting out the codes to be used pursuant to the code systems established in this section shall be published and regularly updated by the Commission with the support of the eHealth Network.
Different branches of the same Marketing Authorisation Holder or the same manufacturer shall use an existing code in the published value set.
As a general rule, for the same vaccine product, the code referring to its marketing authorisation holder in the EU shall be used, as there is no internationally agreed vaccine manufacturer or marketing authorisation holder registry yet. Examples:






—


For the organisation “Pfizer AG”, which is an MAH for vaccine “Comirnaty” used in Switzerland, use code ORG-100030215 referring to BioNTech Manufacturing GmbH, as it is the MAH of Comirnaty in the EU.










—


For the organisation “Zuellig Pharma”, which is an MAH for vaccine Covid-19 Vaccine Moderna (Spikevax) used in the Philippines, use code ORG-100031184 referring to Moderna Biotech Spain S.L., as it is the MAH of Spikevax in the EU.




If this is not possible or advisable in a specific case, a separate code will be provided in the published value set.
5.   Number in a series of doses as well as the overall number of doses in the series

To be used in certificate 1.
Two fields:






(1)


Number in a series of vaccine doses of a COVID-19 vaccine (N);










(2)


Overall number of doses in the vaccination series (C).




5.1.   Primary vaccination series

Where the person is receiving doses of the primary vaccination series, that is, the vaccination series intended to provide sufficient protection at an initial stage, (C) shall reflect the overall number of doses of the standard primary vaccination series (e.g. 1 or 2, depending on the type of vaccine administered). This includes the option of using a shorter series (C=1) where the vaccination protocol applied by a Member State provides for the administration of a single dose of a 2-dose vaccine to persons having previously been infected with SARS-CoV-2. A completed primary vaccination series shall thus be indicated by N/C = 1. For example:






—


1/1 would indicate the completion of a primary single-dose vaccination course, or the completion of a primary course consisting of one dose of a 2-dose vaccine administered to a recovered person in line with the vaccination protocol applied by a Member State;










—


2/2 would indicate the completion of a primary 2-dose vaccination series.




Where the primary vaccination series is extended, for example for persons with severely weakened immune systems or where the recommended interval between primary doses has not been respected, any such doses shall be encoded as additional doses falling under Section 5.2.
5.2.   Additional doses

Where the person is receiving doses following the primary vaccination series, such additional doses (X) shall be reflected in the corresponding certificates by increases in the number of doses administered (N) and overall number of doses (C) (resulting in (N+X)/(C+X)). For example:






—


2/2 would indicate the administration of an additional dose following a primary single-dose vaccination course, or the administration of an additional dose following the completion of a primary course consisting of one dose of a 2-dose vaccine administered to a recovered person in line with the vaccination protocol applied by a Member State;










—


3/3 would indicate the administration of an additional dose following a primary 2-dose vaccination series.




Additional doses administered after the completion of the primary vaccination series shall thus be indicated by (N+X)/(C+X) = 1.
Vaccination certificates issued by 31 December 2021 shall continue to be accepted even if such certificates follow a different rule for encoding the number in a series of doses or the overall number of doses in the series. To ensure this, technical measures may be taken.
Within the legal framework established by Regulation (EU) 2021/953, Member States may take measures to address the situation of vulnerable groups who may receive additional doses as a matter of priority. For example, if a Member State decides to administer additional doses only to specific sub-groups of the population, it can choose, in accordance with Article 5(1) of Regulation (EU) 2021/953, to issue vaccination certificates indicating the administration of such additional doses only upon request and not automatically. Where such measures are taken, Member States shall inform the persons concerned accordingly, as well as that they may continue to make use of the certificate received following the completing of the standard primary vaccination series.
6.   Member State or third country in which the vaccine was administered/test was carried out

Preferred Code System: ISO 3166 Country Codes.
To be used in certificates 1, 2 and 3.
Value set content: the complete list of 2-letter codes, available as a value set defined in FHIR (http://hl7.org/fhir/ValueSet/iso3166-1-2). If the vaccination or test was performed by an international organisation (such as UNHCR or WHO) and no information about the country is available, a code for the organisation shall be used. Such additional codes shall be published and regularly updated by the Commission with the support of the eHealth Network.
7.   The type of test

To be used in certificate 2, and certificate 3 if support for the issuance of recovery certificates based on types of test other than NAAT is introduced through a delegated act.
The following codes shall be used.

8.   Manufacturer and commercial name of the test used (optional for NAAT test)

To be used in certificate 2.
The content of the value set shall include the selection of rapid antigen test as listed in the common and updated list of COVID-19 rapid antigen tests, established on the basis of Council Recommendation 2021/C 24/01 and agreed by the Health Security Committee. The list is maintained by the JRC in the COVID-19 In Vitro Diagnostic Devices and Test Methods Database at: https://covid-19-diagnostics.jrc.ec.europa.eu/devices/hsc-common-recognition-rat
For this code system, relevant fields such as the identifier of the test device, name of the test and manufacturer shall be used, following the JRC structured format available at: https://covid-19-diagnostics.jrc.ec.europa.eu/devices
9.   Result of the test

ANNEX II
Section 3 of Annex III to Implementing Decision (EU) 2021/1073 is replaced by the following:

“3.   General requirements

The following overarching requirements shall be satisfied in relation to the UCI:






(1)


Charset: only uppercase US-ASCII alpha numerical characters (‘A’ to ‘Z’, ‘0’ to ’9’) are allowed; with additional special characters for separation from RFC3986 (1), namely {'/','#',':'};










(2)


Maximum length: designers shall try to aim for a length of 27-30 characters (2);










(3)


Version prefix: this refers to the version of the UCI schema. The version prefix is ‘01’ for this version of the document; the version prefix is composed of two digits;










(4)


Country prefix: the country code is specified by ISO 3166-1. Longer codes (e.g. 3 characters and up (for example, ‘UNHCR’) are reserved for future use;










(5)


Code suffix / Checksum:






5.1


Member States may use a checksum when it is likely that transmission, (human) transcription or other corruptions may occur (that is to say when used in print).










5.2


The checksum shall not be relied upon for validating the certificate and is not technically part of the identifier but is used to verify the integrity of the code. This checksum shall be the ISO-7812-1 (LUHN-10) (3) summary of the entire UCI in digital/wire transport format. The checksum is separated from the rest of the UCI by a '#' character.








Backwards-compatibility shall be ensured: Member States that over time change the structure of their identifiers (within the main version, currently set at v1) shall ensure that any two identifiers that are identical represent the same vaccination certificate/assertion. Or, in other words, Member States cannot recycle identifiers.



(1)  rfc3986 (ietf.org)

(2)  For implementation with QR codes, Member States could consider an extra set of characters up to a total length of 72 characters (including the 27-30 of the identifier itself) may be used to convey other information. The specification of this information is up to the Member States to define.

(3)  The Luhn mod N algorithm is an extension to the Luhn algorithm (also known as mod 10 algorithm) which works for numeric codes and is used for example for calculating the checksum of credit cards. The extension allows the algorithm to work with sequences of values in any base (in our case alpha characters).”
