Abstract:
Although B19 erythrovirus infection may be associated with severe clinical outcomes, especially in early infancy, pregnancy, and in immunocompromised or hemolytic subjects, no vaccine is currently available. Using the concept that effective immune responses to an infectious agent may be restricted to the specific peptidome unique to that agent, we analyzed primary amino acid sequence of B19 erythrovirus, searching for peptide motifs to be used in vaccine formulations. Here, we identify and describe a set of unique viral peptides that may guarantee both high efficacy and practically no cross-reactive autoimmune responses in anti-B19 immunotherapeutic approaches.
