Effectiveness of ChAdOx1 nCoV-19 and BBIBP-CorV vaccines against COVID-19-associated hospitalisation and death in the Seychelles infected adult population.

Background: The Seychelles COVID-19 vaccination campaign was initiated using two different vaccines during the first wave of the pandemic in 2021. This observational study estimated vaccine effectiveness against severe outcomes (hospitalisation and/or death) from individuals infected with COVID-19 in the Seychelles adult population during Beta and Delta variant transmission.

Methods: This nationwide retrospective cohort study included all Seychellois residents aged ≥ 18 years who tested positive by RT-PCR or rapid antigen test for COVID-19 between January 25, 2021, and June 30, 2021.

Erratum to: The prevalence of HIV, HBV, HCV, and HIV-related risk-taking behaviors among Palestinian injecting drug users in the East Jerusalem Governorate.

The objective of the study was to determine HIV, HBV, HCV seroprevalence and to assess HIV risks among Palestinian injecting drug users (IDUs) in the East Jerusalem Governorate. Following formative research, a bio-behavioral survey using respondent-driven sampling was carried out in 2010 among 199 IDUs aged 19-56 years (M = 41.33, SD = 8.

HIV type 1 diversity in the Seychelles.

Subtype determination and drug resistance-associated mutations (DRM) detection were performed on 40 HIV-1 Western blot-positive sera detected, obtained from consecutive patients resident in the Seychelles and consulting the Communicable Disease Control Unit, HIV reference center, in Victoria Hospital (Mahe) from October 2005 to June 2006. Amplification and sequencing of at least two of the partial reverse transcriptase, protease, and partial envelope genes were successful for all strains. All three genes sequences were obtained for 39 strains.
