This research proposal consists of a "spin-off" project based on volunteer samples of the Oxford-UNIFESP ChAdOx1 nCoV-19 vaccine trial. The proposal will involve the 1,000 volunteer samples, and corresponding time points, to primarily establish a repository for the whole academic community of the São Paulo State. This repository will be converted in a Biobank after the project is concluded, as is stated in current legislation. In addition, the samples stored in the Biorepository will be used to perform analysis of these samples that do not overlap with the "Primary and Secondary Outcome Measures" as described in the clinical trial documentation available in (National Institutes of Health, ID NCT04400838). This project will be coordinated by Prof. Luiz Mario Janini and will include a team of principal investigators in different areas pertaining to the specific objectives and research track record at FAPESP. The objectives of this project are: (1) to establish a Biorepository containing all samples obtained from volunteers before and after vaccination. This Biorepository will be available, according to legal procedures, to all São Paulo State scientific community as determined by FAPESP guidelines, (2) to evaluate the neutralizing capacity of sera from vaccinated subjects against Brazilian-specific circulating SARS-CoV-2 strains and other Brazilian-specific strains of coronavirus for assessment of cross immunity, (3) to characterize Brazilian specific isolates of SARS-CoV-2 and study the sequence variation and evolutionary patterns of the SARS-CoV-2 Spike protein in to assess the potential of vaccine escape by modification of the target or epitopes, (4) to generate and analyze cytokine profiles of sera from volunteers before and after vaccination to evaluate the inflammatory response and associated effects, (5) To analyze and compare the blood transcriptomes of volunteers, by RNA-seq, before and after vaccination. This analysis will be quantitative and qualitative to evaluate the impact of the vaccine on differential gene expression levels and assess the individual variation in genetic response to the vaccine and (6) To analyze the whole blood secretome profiles of volunteers, before and after vaccination, to assess the predominant type of immune response and priming by another coronavirus.
