Uma terapia com anticorpos monoclonais, já aprovada no Brasil para tratar casos leves e moderados de COVID-19, revelou agora uma capacidade preventiva expressiva: uma única dose reduziu em 81,6% o risco de doença sintomática ao longo de oito meses. O estudo, conduzido com quase 2.500 pessoas em situação de alto risco, reacende o debate sobre como sistemas de saúde pública podem incorporar inovações científicas quando a logística e os custos impõem seus próprios limites. No Brasil, onde a aprovação regulatória existe mas o acesso pelo SUS permanece incerto, o caso do Regn-Cov2 coloca em relevo

Strengthens Roche/Regeneron's market position in emerging markets; enhances Brazil's regulatory credibility (Anvisa); reduces dependency on vaccines alone for vulnerable populations; positions Brazil as potential regional pharmaceutical hub for preventive treatments.
Similar to early monoclonal antibody approvals in developed nations (2020-2021), but Brazil's approval signals shift toward preventive therapeutics in middle-income countries, potentially fragmenting global COVID response strategies.

High-risk individuals (household contacts of COVID patients, immunocompromised) gain access to preventive treatment option, reducing infection risk and potential healthcare costs. May reduce demand for alternative preventive measures but increases out-of-pocket costs if not covered by public health system.
Anvisa likely to expand authorization from emergency therapeutic use to preventive indication, potentially increasing public procurement costs. Government may need to evaluate coverage under SUS (Unified Health System) for high-risk populations. Regulatory pathway clarification needed for preventive monoclonal antibody use in Brazil.
