### Cohort description


The repository contains metadata for the 30 study participants recruited among health-care workers at the University hospital of Örebro, Sweden. At the start of the study, 14 individuals had a previous Covid-19 infection and 16 were infection naïve. Among the infection naïve group, 75% were female (12 out of 16 participants), with a mean age of 41 years, ranging from 25 to 66 years. In the group with previous Covid-19 infection, 71.4% were female (10 out of 14 participants), with a mean age of 44.6 years, spanning from 29 to 63 years. Study participants were sampled adjacent to each vaccine dose according to the schedule shown in Fig. 1A.


For a more detailed overview of the baseline characteristics please see Table 1 attached in the manuscript.


### Dataset description


Antibody titers measured by ELISA, Percentages of Immunophenotyping of studied cell subsets, and serum protein measurements were compiled into Excel sheets and fully anonymized. This data was provided as supplemental material with the original article. 

RNA-sequencing data: RNA-seq analysis of 99 samples was performed using Illumina sequencing. Preprocessing of FASTQ raw reads was done with the nf-core/rnaseq v3.8 pipeline, with results saved in TSV format. The human genome was appended with vaccine and SARS-CoV-2 related genes prior to read alignment using STAR and gene expression quantification with Salmon.
