To assess the impact of the SARS-CoV-2 booster dose on the immune response against COVID-19, we conducted a cross-sectional study in the Casablanca-Settat region of Morocco. The study included 2,802 participants from 16 provinces, all of whom had received three doses of a SARS-CoV-2 vaccine. IgG antibodies targeting the S1 RBD subunit of the SARS-CoV-2 spike protein were quantified using the SARS-CoV-2 IgG II Quant assay and measured on the Abbott Architect i2000SR instrument.

- - The study identifies the JN.1 variant of SARS-CoV-2 in Morocco through genomic sequencing.
- - Four clinical samples were analyzed, including nasopharyngeal swabs from one female and three male patients.
- - The Illumina COVIDSeq Test was utilized for a thorough genomic analysis of the samples.
Article Synopsis
- SARS-CoV-2 symptoms range from none to severe, with some cases involving serious complications and death, and genetic factors may impact infection risk and severity.
- The study focuses on specific IL-6 gene variants (rs1800795 and rs1800797) in a Moroccan population to assess their link to virus susceptibility and COVID-19 severity.
- While no significant links were found between the gene variants and susceptibility, specific haplotypes (GC* and AG*) were associated with a reduced risk of SARS-CoV-2 infection.
Assessing the prevalence of SARS-CoV-2 IgG positivity through population-based serological surveys is crucial for monitoring COVID-19 vaccination efforts. In this study, we evaluated SARS-CoV-2 IgG positivity within a provincial cohort to understand the magnitude of the humoral response against the SARS-CoV-2 vaccine and to inform evidence-based public health decisions. A community-based cross-sectional seroprevalence study was conducted, involving 10,669 participants who received various vaccines (two doses for BBIBP-CorV/Sinopharm, Covishield vaccine, and Pfizer/BioNTech, and one dose for Johnson & Johnson's Janssen COVID-19 vaccine).

Consequently, their populations have long been controlled using insecticides, in response to which different resistance mechanisms have been selected. Moreover, their ecological preferences and broad adaptability allow C.
