“…A variação de suas infl uências pode ser observada na Figura 4, em que, sobretudo divulgadores científi cos, veículos jornalísticos, jornalistas e políticos disputam relevância. Todavia, a categoria de políticos vence o confronto em todos os estágios, cenário preocupante haja visto o papel que líderes políticos ocupam na profusão dos conteúdos capazes de suscitar, ou aprofundar, a polarização acerca das vacinas (PASCHOALOTTO et al, 2021).…”

Resumo A presente pesquisa é infodemiológica e visa caracterizar a conversação pública acerca da vacina e da vacinação contra a COVID-19 no Brasil sucedida no Twitter. Para mapear os tópicos latentes nos dados coletados (13.2 milhões de tweets), fez-se uso da modelagem de tópicos. Foram identificados 50 tópicos debatidos ao longo do período de análise, 11 dos quais com potencial direto de promoção à hesitação vacinal, categorizados em grupos temáticos, nomeadamente a Accountability, Políticas Públicas, Conflitos, Bioética, Relatos de Experiência, Aspectos Econômicos, Teorias da Conspiração; e Segurança, Eficácia e Importância das Vacinas. Destaca-se o caráter político da conversação, traduzido pelos perfis mais influentes e hashtags acionadas. Todavia, trata-se não apenas de uma política partidária, mas sobretudo cívica, representada pela participação de usuários(as) através do controle social em saúde.

“…The variation in their infl uences is shown in Figure 4, where science communicators, news agencies, journalists and politicians, in particular, argue over relevance. However, politicians won this confrontation at all stages, which is a worrying scenario given the role that political leaders play in the profusion of contents capable of arousing, or deepening, the polarization around vaccines (PASCHOALOTTO et al, 2021).…”

The present research is infodemiological and aims to characterize the public conversation about the vaccine and vaccination against COVID-19 in Brazil that took place on Twitter. To map the latent topics in the collected data (13.2 million tweets), topic modeling was used. since the effectiveness of public vaccination policies is conditioned by its population adherence. From the results, 50 topics were identified and discussed over the period of analysis, 11 of which have direct potential to promote vaccine hesitancy, categorized into thematic groups, namely Accountability, Public Policies, Conflicts, Bioethics, Experience Reports, Economic Aspects, Conspiracy Theories; and Safety, Efficacy and Importance of Vaccines. There was a strong politicization translated by the most retweeted profiles and hashtags used, not only partisan, but mostly civic, represented by users’ participation through the manifestation of social control in health.

BACKGROUND The emergence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants has become a major concern contributing to increased morbidity and mortality worldwide. OBJECTIVES Here we describe the replacement of the Gamma variant of concern (VOC) with Delta in the western Brazilian Amazon. METHODS In this study, we analysed 540 SARS-CoV-2 positive samples determined by qualitative real-time RT-PCR selected in the state of Rondônia between June and December 2021. The positive cohort was sequenced through next-generation sequencing (NGS) and each sample was quantified using real-time RT-qPCR, the whole genome sequence was obtained, SARS-CoV-2 lineages were classified using the system Pango and the maximum likelihood (ML) method was used to conduct phylogenetic analyses. FINDINGS A total of 540 high-quality genomes were obtained, where the Delta VOC showed the highest prevalence making up 72%, with strain AY.43 being the most abundant, while the Gamma VOC was present in 28%, where the P.1 strain was the most frequent. In this study population, only 32.96% (178/540) had completed the vaccination schedule. MAIN CONCLUSIONS This study highlighted the presence of Gamma and Delta variants of SARS-CoV-2 in RO. Furthermore, we observed the replacement of the Gamma VOC with the Delta VOC and its lineages.
