Brief Summary

Asthma is a major health problem in preschool children. Infections by pneumococci a the most frequent cause of airway infections, which tend to cause worsening of asthma. Vaccination against pneumococci is recommended by scientific boards and the medical community, in order to reduce the burden of disease. Data on the immunogenicity and safety of pneumococcal immunization in preschool asthmatics are scarce.
