Journal ArticleDOI
Burden of disease caused by Streptococcus pneumoniae in children younger than 5 years: global estimates
Katherine L. O'Brien,Lara J. Wolfson,James P. Watt,Emily Henkle,Maria Deloria-Knoll,Natalie McCall,Ellen Lee,Kim Mulholland,Orin S. Levine,Thomas Cherian +9 more
TL;DR: The burden of pneumococcal pneumonia is measured by applying the proportion of pneumonia cases caused by S pneumoniae derived from efficacy estimates from vaccine trials to WHO country-specific estimates of all-cause pneumonia cases and deaths, using disease incidence and case-fatality data from a systematic literature review.
Journal ArticleDOI

Thomas Cherian,E. Kim Mulholland,John B. Carlin,Harald Østensen,Ruhul Amin,Margaret de Campo,David Greenberg,Rosanna Lagos,Marilla G. Lucero,Shabir A. Madhi,Katherine L. O'Brien,Steven Obaro,Steven Obaro,Mark C. Steinhoff +13 more
TL;DR: Using standardized definitions and training, it is possible to achieve agreement in identifying Radiological pneumonia, thus facilitating the comparison of results of epidemiological studies that use radiological pneumonia as an outcome.
Journal ArticleDOI
Burden of disease caused by Haemophilus influenzae type b in children younger than 5 years: global estimates.
James P. Watt,Lara J. Wolfson,Katherine L. O'Brien,Emily Henkle,Maria Deloria-Knoll,Natalie McCall,Ellen Lee,Orin S. Levine,Rana A. Hajjeh,Kim Mulholland,Thomas Cherian +10 more
TL;DR: Global burden of Hib disease is substantial and almost entirely vaccine preventable, and expanded use of Hib vaccine could reduce childhood pneumonia and meningitis, and decrease child mortality.
Journal ArticleDOI
Serotype-specific changes in invasive pneumococcal disease after pneumococcal conjugate vaccine introduction: a pooled analysis of multiple surveillance sites.
Daniel R. Feikin,Eunice W. Kagucia,Jennifer D. Loo,Ruth Link-Gelles,Milo A. Puhan,Thomas Cherian,Orin S. Levine,Cynthia G. Whitney,Katherine L. O'Brien,Matthew R. Moore +9 more
TL;DR: In a pooled analysis of data collected from invasive pneumococcal disease surveillance databases, Daniel Feikin and colleagues examine serotype replacement after the introduction of 7-valent pneumococCal conjugate vaccine (PCV7) into national immunization programs.
Journal ArticleDOI
