Mariela Viceconte filed a collective amparo action seeking to force the Argentine State to produce the Candid 1 vaccine. Her case was based on her own right to health and that of other persons exposed to contracting Argentine Hemorrhagic Fever, including in Argentina approximately 3.5 million people. The action specifically alleged a violation of the obligation to prevent, treat and fight epidemic and endemic diseases arising from article 12.2.c) of the International Covenant on Economic, Social and Cultural Rights (ICESCR).
