Impact of Vaccination Time on Anti-SARS-CoV-2 Antibody Levels in Adults: A Quasi-experimental Study.

Background And Aim: Vaccination time may provide an opportunity to advance immunogenicity in terms of the immune system's circadian nature. This analytical study was planned to determine the impact of forenoon and afternoon administration of the COVID-19 vaccine to adults on the magnitude of antibody response.

Method: A total of 33 healthy adults with no history of COVID-19 infection or any other disease participated in the study.

Automatic segmentation of layers in chorio-retinal complex using Graph-based method for ultra-speed 1.7 MHz wide field swept source FDML optical coherence tomography.

The posterior segment of the human eye complex contains two discrete microstructure and vasculature network systems, namely, the retina and choroid. We present a single segmentation framework technique for segmenting the entire layers present in the chorio-retinal complex of the human eye using optical coherence tomography (OCT) images. This automatic program is based on the graph theory method.

Adverse events following COVID-19 immunisation (AEFI) at a COVID-19 vaccination centre: An observational analytical study.

Objectives: The aim of this study was to determine the adverse events following immunisation (AEFI) in various age groups after coronavirus disease 2019 (COVID-19) vaccination and assess the association of comorbidities with AEFI.

Methods: An observational analytical study was conducted among the general population who had received both doses of the COVID-19 vaccine. A total of 389 participants from the 18-44 years age group, 380 participants from the 45-60 years age group and 373 participants from the 60 plus age group were enrolled in the study after verbal and written consent.
