Despite the well-documented life-saving potential of pneumococcal conjugate vaccines (PCV) and global efforts to widen vaccine availability, access PCV in middle-income countries (MICs) has remained suboptimal due, part, pricing limited external funding opportunities. To understand gaps opportunities for improving equality, this qualitative study engaged leaders from governments, medical institutions, health agencies who were based MICs that did not currently have their national immunization...

Abstract Pneumonia remains the leading infectious cause of global childhood deaths, despite availability World Health Organization (WHO)-prequalified pneumococcal conjugate vaccine (PCV) products and evidence their safety efficacy for over two decades, along with financial technical support from Gavi The Vaccine Alliance (Gavi). There are 39 remaining “last-mile” countries (33 low- middle-income [LMICs] six high-income countries) that haven’t fully included PCV in National Immunization...
