As announced by the Argentine authorities, the country has been chosen by some international laboratories, in order to test the effectiveness of vaccines against the coronavirus, which causes the disease known as COVID-19, by carrying out a series of tests on a sample of people, taking as parameters issues such as age, sex, previous disease conditions, among other factors.

In Argentina, there is a specific regulatory framework for conducting tests on the human body, which includes not only common law – civil law – but also specific rules and even provisions of public bodies that regulate issues related to said tests.

The main rules applicable to the development of this type of activities – going from the most general to the most specific – will be succinctly developed, in which are immersed questions about the disposition of the body itself, informed consent, transfer of personal data, sensitive data processing

2.Legal Framework.

a) Law 26,994. Civil and Commercial Code.

The civil and commercial code is applicable to the case of informed consent, regulating the acts of disposition that a person can carry out on the body itself, including investigations in human beings.

Article 58 establishes the requirements that need to be carried out when a person is a study subject or participant in medical research in humans through interventions, such as treatments, prevention methods, diagnostic or predictive tests, whose efficacy or safety are not scientifically proven.

Article 59 for its part, regulates informed consent regarding medical acts and health research.

b) Law 25326. Protection of Personal Data.

The conduct of clinical trials also involves sensitive personal data, by relating such trials to very personal and fundamental issues related to the dignity of the person, which have the status of human rights.

In Argentina, the law that regulates the protection of personal data in general, and sensitive data in particular is Law 25326.

This law establishes that sensitive data is “… Personal data that reveals the racial and ethnic origin, political opinions, religious, philosophical or moral convictions, affiliation, and information regarding health or sexual life.”

Likewise, in its article 7, when dealing with the category of data, and when referring to sensitive data, the law prescribes the following: “ARTICLE 7 – (Category of data). 1. No person can be forced to provide sensitive data. 2. Sensitive data can only be collected and processed when there are reasons of general interest authorized by law. They may also be treated for statistical or scientific purposes when their holders cannot be identified. ”

In section 2, the law refers to the process of data anonymization that consists of dissociating the data itself in relation to the determined or determinable person, holder of that data, through a certain process.

Article 8 of the law also mandates that, regarding health-related data, “Public or private healthcare establishments and professionals linked to the health sciences may collect and process personal data related to the physical or mental health of patients who come to them or who are or have been under treatment by them, respecting the principles of professional secrecy. “

Regarding the consent of the owner of personal data, Article 5 of the Data Protection Law prescribes that “(…) the free, express and informed consent will be required, which must be in writing, or by any other means that allows match it, according to the circumstances. The aforementioned consent given with other declarations must appear expressly and prominently, prior notification to the requested data, of the information described in article 6 of this law. “

Specifically speaking of international personal data transfer –sensitive data in particular-, article 12 exceptionally authorizes the transfer of said type of data only in an epidemiological investigation, as long as it is carried out under the terms of subsection e) of Article 6 –only when an anonymization procedure is applicable to the data collected-.

c) Resolution 1480/2011 and Disposition 6677/2010 from the Health Regulatory Authority –ANMAT-

c.1) Res. 1480/2011, Point A3. provides a definition of what informed consent has to be considered when a clinical trial is being carried out. The rule establishes that “As a general principle, consent must be obtained for all research involving human beings or carried out with biological samples or personal data.” In connection with this, the test subject will have to be informed the measures that will be taken to protect the confidentiality of personal data.

Regarding the confidentiality of the information obtained from the test subjects, point A6 prescribes that personally identifiable data should not be used when a study can be done without it. When it is necessary to record personal identification data, researchers must justify that need. For this purpose the consent has to be obtained. Furthermore, point A8. Regarding the management of the data and the results, prescribes the obligation for the researches to secure the personal data.

c.2) Disposition 6677/2010 from the Argentinean Health Regulatory Authority. Regime of Good Clinical Practices for Clinical Pharmacology Studies.

This provision states:

  1. a) That researchers must ensure the confidentiality of the information in the stages of preparation, execution and completion of the study, as well as the identity of the people incorporated into it;
  2. b) That the protocols contain confidentiality considerations;
  3. c) That it is an indispensable requirement for the approval of a clinical trial, the presentation of an informed consent form in which the person is informed: objectives, methods, advantages, therapeutic alternatives and possible risks inherent in the study and that it is free to withdraw their consent to participate, at any time, without explaining the causes.

3) Conclusions:

  • That the signing of the informed consent does not imply the resignation of the patient to any of the rights provided in the current legal regulations.
