Is Higher Viral Load in SARS-CoV-2 Associated with Death?

There is no proven prognostic marker for patients hospitalized with COVID-19. We conducted a retrospective cohort study of patients hospitalized with COVID-19 from March 14, 2020 to June 17, 2020, at São Paulo Hospital, in São Paulo, Brazil. SARS-CoV-2 viral load was assessed using the cycle threshold (Ct) values obtained from a reverse transcription-PCR assay applied to the nasopharyngeal swab samples.

Enhances the Immunogenicity of HIVBr18 Human Immunodeficiency Virus-1 Vaccine.

Immunization of BALB/c mice with HIVBr18, a DNA vaccine containing 18 CD4 T cell epitopes from human immunodeficiency virus (HIV), induced specific CD4 and CD8 T cell responses in a broad, polyfunctional and persistent manner. With the aim of increasing the immunogenicity of this vaccine, the effect of as an adjuvant was evaluated. The adjuvant effects of this bacterium have been extensively demonstrated in both experimental and clinical settings.
