ß-thalassemia Major Clinical Trial
Official title:
Study of the B Memory Cell Response to Vaccination With the 13-valent Pneumococcal Conjugate Vaccine in Asplenic Individuals With Beta-thalassemia Major
The purpose of this study is to determine whether one dose of the 13-valent pneumococcal conjugate vaccine (PCV13) induces immunological memory in asplenic adults and whether previously administered immunizations with the 23-valent polysaccharide pneumococcal vaccine influence the cellular immune response to PCV13 in this group.
