One notable area of focus has been the investigation of existing drugs for potential repurposing as treatments. Among these, chloroquine and hydroxychloroqine gained significant attention, largely due to early endorsements by high-profile figures. However, rigorous clinical trials conducted in Brazil and globally have since shown limited to no efficacy in treating COVID-19, with potential risks of side effects such as cardiac arrhythmias. Despite this, the debate around these drugs highlights Brazil’s proactive approach to exploring treatment options, even if some paths proved unfruitful.
Another key aspect of Brazilian COVID-19 treatment research has been the emphasis on monoclonal antibodies. The country has participated in international trials and collaborated with global pharmaceutical companies to test these therapies. For instance, the use of regdanvimab and sotrovimab has been studied in Brazilian hospitals, particularly for high-risk patients. These antibodies, administered via intravenous infusion, aim to neutralize the virus and prevent severe disease progression. While not a cure, they represent a targeted approach to managing the infection, especially in the early stages. Patients eligible for this treatment typically include those over 65 or with comorbidities such as diabetes, obesity, or cardiovascular disease.
Brazil has also explored the potential of convalescent plasma therapy, a treatment that uses blood plasma from recovered COVID-19 patients to provide antibodies to those currently infected. Early studies in Brazilian hospitals showed mixed results, with some patients experiencing improved outcomes, particularly when administered within the first week of symptom onset. However, larger randomized controlled trials have since suggested that the benefits may be modest and inconsistent. Practical considerations, such as the need for compatible blood types and the risk of transfusion reactions, have also limited its widespread adoption. Despite this, the research underscores Brazil’s commitment to investigating diverse treatment modalities.
In addition to pharmaceutical interventions, Brazil has invested in traditional and complementary medicine research, particularly in the Amazon region. Studies have examined the antiviral properties of plants like Andiroba and Açaí, though these remain in the early stages of scientific validation.

Brazil's role in vaccine trials
Brazil played a pivotal role in the global race to develop COVID-19 vaccines, serving as a critical testing ground for several leading candidates. Its large and diverse population, coupled with high virus circulation, made it an ideal location for phase III clinical trials, which require thousands of participants to assess vaccine efficacy. Notably, Brazil hosted trials for AstraZeneca, Sinovac, and Pfizer vaccines, contributing significantly to their approval and global distribution. For instance, the University of São Paulo’s partnership with Sinovac led to the development of CoronaVac, which became a cornerstone of Brazil’s vaccination campaign. This involvement not only accelerated vaccine availability but also positioned Brazil as a key player in pandemic response.
One of the most striking examples of Brazil’s contribution is the Butantan Institute’s collaboration with Sinovac. By late 2020, over 12,000 volunteers across six Brazilian states participated in CoronaVac trials. The results, showing 50.7% efficacy in preventing symptomatic COVID-19 and 100% effectiveness against severe cases, were pivotal in securing regulatory approval. This vaccine was particularly advantageous in Brazil due to its ease of storage (2°C to 8°C), making it accessible in remote areas with limited infrastructure. The institute’s ability to produce 100 million doses locally further underscored Brazil’s self-sufficiency in vaccine distribution.
However, Brazil’s role in vaccine trials was not without challenges. The country faced political interference, logistical hurdles, and public skepticism, which delayed trial enrollment and vaccine rollout. For example, the AstraZeneca trial was temporarily halted in late 2020 following a participant’s death, though it was later determined to be unrelated to the vaccine. Such incidents highlight the complexities of conducting large-scale trials during a global health crisis. Despite these obstacles, Brazil’s scientific community persevered, ensuring that trial data remained robust and transparent.
Practical lessons from Brazil’s experience offer valuable insights for future pandemic responses.

Local remedies tested for COVID-19
During the COVID-19 pandemic, Brazil, like many countries, explored local remedies as potential treatments. One widely discussed example was the use of chloroquine and hydroxychloroqine, antimalarial drugs promoted by some Brazilian officials despite limited scientific evidence. These drugs were prescribed off-label, often in combination with azithromycin, an antibiotic. However, studies later showed no significant benefit and highlighted risks such as cardiac arrhythmias, leading health authorities to caution against their use.
Another local remedy tested in Brazil was green propolis, a bee-derived resin with purported antiviral and anti-inflammatory properties. Researchers investigated its active compound, artepillin C, for its potential to inhibit viral replication. While preliminary lab studies showed promise, clinical trials were limited in scope, and no definitive conclusions were drawn. Propolis supplements, typically taken as 500 mg capsules twice daily, remain popular in Brazil but are not officially endorsed as COVID-19 treatments.
Herbal remedies also gained attention, with Andiroba oil, extracted from the seeds of the *Carapa guianensis* tree, being tested for its anti-inflammatory effects. Traditionally used to treat skin conditions and pain, Andiroba was explored as a supportive therapy for COVID-19 symptoms. However, its efficacy remains unproven, and its use is largely anecdotal. Practical application involves topical application or oral consumption in small doses, though specific guidelines are lacking.
A more structured approach was taken with serotherapy, using convalescent plasma from recovered COVID-19 patients. Brazilian hospitals conducted trials to assess its effectiveness in reducing disease severity. While some patients showed improvement, results were inconsistent, and the treatment’s feasibility was limited by donor availability and logistical challenges. This method underscores the importance of evidence-based medicine over unproven remedies.
In contrast to these efforts, Brazil’s reliance on unproven treatments highlights the risks of bypassing rigorous scientific validation. While local remedies may offer cultural or historical significance, their use in a global health crisis must be guided by clinical trials and peer-reviewed data. As the pandemic evolves, Brazil’s experience serves as a cautionary tale about balancing tradition with scientific rigor in the pursuit of effective treatments.
