Pneumococcal Infections Clinical Trial
Official title:
An Open, Multicenter Clinical Trial to Investigate the Immunogenicity and Safety of the Pneumococcal 7-Valent Conjugate Vaccine (PREVENAR) in Sickle Cell Disease Infants.
The primary objectives of this study were to assess the immunogenicity and the tolerance of the heptavalent pneumococcal conjugate vaccine (Prevenar) in young infants (2 months of age) with sickle cell disease when administred at 2,3, and 4 months of age.
