Dear Editor:
The COVID-19 pandemic has strongly affected the Brazilian indigenous population, with over 45,000 people infected, an incidence of 5,782 cases/100,000 people and more than 600 deaths11. Ministério da Saúde (MS). Secretaria de Vigilância em Saúde. Sistema Nacional de Vigilância em Saúde. Boletim Epidemiológico COVID-19: Situação dos casos Distrito Sanitário especial Indígena de Mato Grosso do Sul. Brasília: MS; 2021.. Despite efforts to contain the spread of this disease, the number of cases continues to increase. The second largest indigenous reserve in the country, which is located in the city of Dourados, Mato Grosso do Sul State, saw 445 new cases in January 2021 among its approximately 18,000 indigenous inhabitants-an incidence of 2,472 cases/100,000 inhabitants in 1 month, which is 14% higher than the incidence for the entire year of 2020. Among all indigenous people, 753 were diagnosed with COVID-19 in the first trimester of 2021 alone11. Ministério da Saúde (MS). Secretaria de Vigilância em Saúde. Sistema Nacional de Vigilância em Saúde. Boletim Epidemiológico COVID-19: Situação dos casos Distrito Sanitário especial Indígena de Mato Grosso do Sul. Brasília: MS; 2021.. These findings indicate that massive vaccination of this population is needed to control the disease.
In mid-January 2021, an immunization campaign began among indigenous people over 18 years old-approximately 410,000 people. A comprehensive search of the number of indigenous people vaccinated per unit of the federation (UF) was performed using the vaccination monitoring system of the Brazilian health system. By April 28, only 32.44% of the total indigenous population (249,291/774,024 people) and 60.91% of the adult population (249,291/409,883 people) had received the booster dose (Figure 1 and Table 1)22. Ministério da Saúde (MS). Secretaria de Vigilância em Saúde. Sistema Nacional de Vigilância em Saúde. Imunização Indígena: COVID-19. Brasília: MS ; 2021.. Of the 18 states evaluated, six had not vaccinated more than 30% of the total population with the booster dose, and only two states-Ceará (68%) and Paraíba (62%)-had achieved a 60% vaccination rate among the total indigenous population (Figure 1 and Table 1).
Percentage of COVID-19 vaccine doses in the total Brazilian Indigenous population of each Indigenous Special Sanitary District federative headquarters until April 28, 2021.
The Indigenous Special Sanitary District (ISSD) of Mato Grosso do Sul hosts the second largest indigenous population in the country (83,434 people) (Table 1), and it features villages that are geographically accessible to an urban center33. Brasil. Instituto Brasileiro de Geografia e Estatística: Mapa de distribuição da população indígena no Brasil. Brasil: IBGE;2010. https://indigenas.ibge.gov.br/
https://doi.org/https://indigenas.ibge.g...
. For these reasons, several vaccination sites were created inside this ISSD and, in specific cases, health teams were dispatched to patients’ homes. Unfortunately, even with these strategies, the percentage of vaccinated people 2 months later was still below that expected. Prior to April 28, only 35,790 indigenous people had received the first dose of the CoronaVac™ vaccine in ISSD/MS, which corresponds to 43.3% of the total population and 78% of adults. Similarly, 29,613 people had received the booster dose (35.6% of the total population and 64% of adults) (Figure 1 and Table 1)22. Ministério da Saúde (MS). Secretaria de Vigilância em Saúde. Sistema Nacional de Vigilância em Saúde. Imunização Indígena: COVID-19. Brasília: MS ; 2021.. Because the vaccination uptake was low, the unused doses were distributed to other groups of non-indigenous individuals, such as health professionals and the elderly.
In 2019, before the coronavirus pandemic and the flood of anti-vaccine news, only three states had an influenza vaccination coverage below 90% among the indigenous population (Amapá: 88.93%, Paraíba: 89.31%, and Mato Grosso do Sul: 82%)44. Ministério da Saúde (MS). Secretaria de Vigilância em Saúde. Sistema de Informação do Programa Nacional de Vacinação. Brasil: MS; 2021.. On the other hand, these states had lower rates of vaccination for COVID-19. In addition, the rates of vaccination in Acre, Roraima, and Santa Catarina states, did not reach 30% of the total indigenous population (Figure 1 and Table 1)22. Ministério da Saúde (MS). Secretaria de Vigilância em Saúde. Sistema Nacional de Vigilância em Saúde. Imunização Indígena: COVID-19. Brasília: MS ; 2021.. The low vaccination uptake among indigenous populations is a public health emergency as it may lead to an increase in the number of cases, especially cases of the new Brazilian SARS-CoV-2 Gamma variant55.

The COVID-19 pandemic has exposed the constant social vulnerability of indigenous peoples in Brazil, such as the precariousness of health services, housing conditions, and education66.

. This scenario, along with fake news about vaccines, must have contributed to the low vaccine roll-out88.

. Many fake news attempts to disparage the vaccine have made false assertions about its effects, claiming that the vaccine contains monitoring chips or that it leads to genetic alterations1010. Peet C. Aljazira [Internet]. COVID rumours hamper Brazil’s efforts to vaccinate Indigenous. Alzajera;2021 [updated on February 18, 2021; cited on May 21, 2021].

https://www.aljazeera.com/news/2021/2/18...
. The fake news spread on social media, which is the main source of information for indigenous people, has been buttressed by discourse from important Brazilian politicians1111. Hallal PC. SOS Brazil: science under attack. The Lancet 2021; 397:373-4.. While most world leaders gathered to discuss the vaccine, Brazil, which was once a world example with its National Vaccination Program88. Domingues CMAS, Maranhão AGK, Teixeira AM, et al. 46 anos do Programa Nacional de Imunizações: uma história repleta de conquistas e desafios a serem superados. Cad Saúde Pública 2020;36:e00222919., saw its leaders discussing and instigating the use of drugs without scientific evidence1111. Hallal PC. SOS Brazil: science under attack. The Lancet 2021; 397:373-4.,1212. Shalders A. BBC News [Internet]. “Tratamento precoce”: governo Bolsonaro gasta quase R$ 90 milhões em remédios ineficazes, mas ainda não pagou Butantan por vacinas.

.
Unfortunately, the anti-vaccine rhetoric and misinformation circulated throughout the country also reached Brazilian indigenous reserves, thus discouraging vaccination1010. Peet C. Aljazira [Internet]. COVID rumours hamper Brazil’s efforts to vaccinate Indigenous. Alzajera;2021 [updated on February 18, 2021; cited on May 21, 2021]. Available from: Available from: https://www.aljazeera.com/news/2021/2/18/covid-rumours-hamper-brazils-efforts-to-vaccinate-indigenous .
https://www.aljazeera.com/news/2021/2/18...
. In addition, some indigenous deaths at the beginning of the vaccination process caused insecurity within this population, even though the incidents were not associated with SARS-CoV-2 vaccination66. Articulação dos povos indígenas do Brasil/APIB [Internet]. Relatório: Emergência Indígena. APIB; 2021 [updated on May 21, 2021; cited on May 21, 2021]. Available from: Available from: https://apiboficial.org/emergenciaindigena/
https://apiboficial.org/emergenciaindige...
. These factors, in addition to the ever-present lack of educational material produced in indigenous languages, may have contributed to the low vaccination coverage. In a joint effort, universities and some non-governmental organizations have been producing educational material in native indigenous languages since the beginning of the pandemic, trying to clear doubts about COVID-1966. Articulação dos povos indígenas do Brasil/APIB [Internet]. Relatório: Emergência Indígena. APIB; 2021 [updated on May 21, 2021; cited on May 21, 2021]. Available from: Available from: https://apiboficial.org/emergenciaindigena/
https://apiboficial.org/emergenciaindige...
. These efforts need to be encouraged by the federal government and health agencies to broaden the amount of correct information about this disease and effective ways to reduce its spread. Higher vaccine uptake, extensive testing, use of masks, social isolation, and hand hygiene need to be intensified to reduce the number of new deaths due to COVID-19 among Brazilian indigenous populations.
