Highly pathogenic avian influenza: Pandemic preparedness for a scenario of high lethality with no vaccines
Highly Pathogenic Avian Influenza (HPAI) viruses, particularly H5N1 and H7N9, have long been considered potential pandemic threats, despite the absence of sustained human-to-human transmission. However, recent outbreaks in previously unaffected regions, such as Antarctica, suggest we may be shifting from theoretical risk to a more imminent threat. These viruses are no longer limited to avian populations. Their increasing appearance in mammals, in…

Vaccines for neglected and emerging diseases in Brazil by 2030: The "valley of death" and opportunities for RD&I in Vaccinology 4.0
We examine the implications of the very low competitiveness of the Brazilian vaccine RD&I system, which precludes the development of all the important vaccines required by the National Immunization Program (NIP), severely impacting the healthcare of the population. In a country dramatically affected by COVID-19 pandemic and by an exponential increase in emerging and neglected diseases, particularly the poor, these RD&I constraints for vaccines be…
Emerging Issues: Pharmaceuticals and Patents in Developing Countries
This article analyses the Intellectual Property Rights (IPR) debateon pharmaceuticals, an issue introduced by TRIPS, a World TradeOrganization(WTO) Agreement on Trade Related Aspects of Intellectual PropertyRights which included pharmaceuticals as subject to patents, equivalent toany other product in the market. Available research results indicate that patentinglife saving products, such as antiretroviral (ARV) drugs, is controversial, since itcr…
Debate on the paper by David Waltner-Toews
Disease and health outcomes occur within a complex socio-ecological context characterized by feedback loops across space and time, self-organization, holarchies, and sudden changes in organization when thresholds are reached. Disease control programs, even if they are successful, may undermine health; conversely, programs in agriculture and economic development designed to improve health may simply alter disease patterns. A research and developme…
Social ecosystem health: Confronting the Complexity and Emergence of Infectious Diseases
The emergence and re-emergence of infectious diseases and their rapid dissemination worldwide are challenging national health systems, particularly in developing countries affected by extreme poverty and environmental degradation. The expectations that new vaccines and drugs and global surveillance would help reverse these trends have been frustrated thus far by the complexity of the epidemiological transition, despite promising prospects for the…
Estado, movimentos sociais e reformas na América Latina: Uma Reflexão Sobre a Crise Contemporânea
Este artigo discute os sistemas de proteção social na América Latina e as perspectivas para reformas sociais na região, tomando como referência os padrões existentes de relacionamento entre a sociedade e o Estado. Duas abordagens presentes na literatura sobre o tema são analisadas e questionadas: a primeira diz respeito à adoção de tipologias referidas às diferentes modalidades de Welfare State na classificação dos distintos sistemas de proteção …
Oferta tecnológica para o desenvolvimento em saúde: O caso da Fiocruz
O presente trabalho apresenta a proposta metodológica e os resultados consolidados do levantamento realizado, de modo descontínuo, ao longo de período de 6 meses (outubro de 86 a março de 87) da oferta tecnológica da FIOCRUZ. As definições conceituais e os procedimentos utilizados são apresentados de modo detalhado, por tratar-se de trabalho inédito na área de saúde. Também são apresentadas as 76 ofertas mapeadas, tecendo-se breves comentários, s…
