Worldwide, medical doctors and lawyers cooperate in health justice projects. These professionals pursue the ideal that, one day, every individual on Earth will be equally protected from the hazards that impair health. The main hindrances to health justice are discrimination, poverty and segregation, but we know that beyond concrete, quantifiable barriers, symbolic elements such as beliefs and fears also play a significant role in perpetuating health injustice. So, between March 2020, when the World Health Organization declared COVID-19 a global pandemic, and June 2021, when vaccines against the virus were globally available, we collected original information about the ways in which four Colombian Indigenous communities confronted COVID-19. Knowing that Colombian Indigenous communities often face health injustices, our goal was to understand the role of symbolic elements in the situation. Our main insight is that historical genocidal processes, in which the powerful have betrayed the trust of Indigenous communities, have created a trauma in the latter, resulting in reluctance and suspicion regarding the acceptance of ‘gifts’ from external sources, including potentially beneficial health treatments.
