Streptococcus pneumoniae is a major cause of morbidity and mortality in children less than 5 years of age. Prevention of pneumococcal disease and death in children in the developing world through vaccination with recently developed, highly efficacious pneumococcal conjugate vaccines (PCVs) is now possible. Schedules combining PCV with 23-valent pneumococcal polysaccharide vaccine (PPV23) have b...
CONTEXT A conjugate vaccine targeting 7 pneumococcal serotypes was licensed for young children in 2000. In contrast to the 23-valent polysaccharide vaccine used in adults, the 7-valent conjugate vaccine affects pneumococcal carriage and transmission. Early after its introduction, incidence of invasive pneumococcal disease declined among older adults, a group at high risk for pneumococcal diseas...
Streptococcus pneumoniae is a major cause of severe disease worldwide, particularly in the elderly population. Due to increasing life expectancy in Japan and elsewhere, an effective vaccine which offers the possibility of prolonged protection is required. Protein conjugated pneumococcal vaccines, which have the ability to boost immunity (immunologic memory) on natural exposure or revaccination,...
A new conjugate 7-valent vaccine to prevent pneumococcal infection (Prevenar, Wyeth) has recently received a European licence for use in young healthy children. The vaccine is not currently included in the universal immunisation schedule in the UK or elsewhere in Europe, although it is being used widely in the USA. Its availability for purchase raises the question whether paediatricians should ...
INTRODUCTION S. pneumoniae can cause a wide spectrum of diseases, including invasive pneumococcal disease and pneumonia. Two types of pneumococcal vaccines are indicated for use in adults: 23-valent pneumococcal polysaccharide vaccines (PPV23) and a 13-valent pneumococcal conjugate vaccine (PCV13). OBJECTIVE To systematically review the literature assessing pneumococcal vaccine effectiveness ...
Diabetes mellitus is associated with increased risk of pneumonia, and 23-valent pneumococcal polysaccharide vaccine (PPV23) is recommended for prevention of pneumonia. However, the effectiveness of PPV23 remains unclear in the older diabetic patients who usually have compromised immune function.We used data extracted from the Taiwanese National Health Insurance Research Database (NHIRD) from 20...
CONTEXT Pneumococcal polysaccharide vaccine is recommended for elderly persons and adults with certain chronic illnesses. Additionally, a recently licensed pneumococcal 7-valent conjugate vaccine has been recommended for use in young children and could dramatically change the epidemiology of pneumococcal disease. OBJECTIVES To assess pneumococcal disease burden in the United States, estimate ...
