CD40LG and infection: The dataset was used to help answer relevant questions, including: (i) do early sub-microscopic infections induce IgM and IgG Ab to the 8 antigens or is parasitaemia detected by microscopy required to induce a response?; (ii) do babies produce both IgM and IgG Abs upon primary infection?; (iii) do infants produce IgM and/or IgG Ab in the presence of maternal IgG Abs?; and, (iv) is the Ab repertoire produced during the initial response the same as that produced during the first clinical malaria episode?
