Vaccine effectiveness against onward transmission of SARS-CoV2-infection by variant of concern and time since vaccination, Belgian contact tracing, 2021.

a re-assessment. METHODS: We estimated VE against transmission of infection (VET) from Belgian contact tracing data for high-risk exposure contacts between 26/0½021 and 14/12/2021 by susceptibility (VE s) and ...

Poor antibody response to BioNTech/Pfizer COVID-19 vaccination in SARS-CoV-2 naïve residents of nursing homes.

death and may respond poorly to vaccination because of old age and frequent comorbidities. METHODS: Seventy-eight residents and 106 staff members, naïve or previously infected with SARS-CoV-2, were ...

Controlled Human Infection Studies: Proposals for guidance on how to design, develop and produce a challenge strain.

followed by use of qualified methods to test critical steps in the manufacturing process, or the final product itself. These activities are complementary: GMP rules, which intervene only at the time of the ...

Development of vibrational spectroscopic methods combined with chemometrics for the detection and quantification of nicotine in e-liquids.

be respected (< 20mg/ml). The main objective of this paper is to develop a handheld NIR, Raman or SERS spectroscopic method combined with chemometrics (PLS and PCA) for detection and quantification ...

CBD oils on the Belgian market: A validated MRM GC-MS/MS method for routine quality control using QuEChERS sample clean up

CBD content not always corresponds to the label claim. There is a pressing need to develop new analytical methods specifically developed to the assay of such oily samples. Analytical issues are, ...

Deepening of In Silico Evaluation of SARS-CoV-2 Detection RT-qPCR Assays in the Context of New Variants

Abstract: For 1 year now, the world is undergoing a coronavirus disease-2019 (COVID-19) pandemic due to the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The most widely used method for ...

Use of Whole Genome Sequencing Data for a First in Silico Specificity Evaluation of the RT-qPCR Assays Used for SARS-CoV-2 Detection.

RT-qPCR methods were developed in January 2020 for initial in silico specificity evaluation and to verify whether the targeted loci are highly conserved. Now that more whole genome data have become ...
