Here you will find the raw data (RawData.RData) and code (CHIVAS_SEROLOGY_Code.Rmd, an R Markdown file) for generating the analysis and figures for the following publication: Streptococcus pyogenes pharyngitis elicits diverse antibody responses to key vaccine antigens influenced by the imprint of past infections.

Each timepoint and isotype for each antigen as seperate column) "data_long": Data equivalent to "data" file but in long format, i.e. One column for each antigen, timepoint and isotype as factors. "data.melt" : Data equivalent to "data" file but in longer format , i.e. timepoint, isotype and antigen as factors, 'value' as ELISA AU. "luminex" : IgG responses to 6 antigens analysed by luminex bead-based assay in human challenge participants. "luminex.children" : IgG responses to 6 antigen analysed by luminex bead-based assay in children Vectors: "pharyngitis" : participant "id" for the 19 individuals that developed pharyngitis. "Antigen.Order" : relates to "Main" antigen classification used in Figure 2 'additional" : relates to "Additional Function: "custom_theme" : used as a theme when using ggplot to graph. Adobe Illustrator or Inkscape were used to generate the final image files for publication, with some graph editing to axes labels, font size, adding p-values etc. Additional files: 3 .csv files have been included for download "ELISA_data_wide_format.csv", a wide format data table of 25 human challenge individuals and 219 variables. Equivalent to the 'data' dataframe in the RData file "CHIVAS_luminex.csv", a long format data table of 25 human challenge participants at 1 week, 1 month, and 3 months. Equivalent to the 'luminex' dataframe in the RData file. "Luminex.children.csv", a datatable of 6 luminex variables for 39 children (healthy and post pharyngitis). Equivalent to the 'luminex.children' dataframe in the RData file.
