Study to Evaluate 13 Valent Pneumococcal Conjugate Vaccine (13vPnC) Vaccine Followed by 23-valent Pneumococcal Polysaccharide Vaccine (23vPS) Vaccine in Allogeneic Hematopoietic Stem Cell Transplant Recipients

People who have received an allogeneic hematopoetic stem cell transplant (HSCT) are more likely than other people to get ill from a germ called Streptococcus pneumoniae. Most people who have had a stem cell transplant are offered a vaccine called 23-valent pneumococcal polysaccharide vaccine (23vPS) to help protect against this germ. The purpose of this study is to evaluate the immune response in HSCT recipients who receive a 13 valent pneumococcal vaccine (13vPnC) followed by 23vPS.
