BWC confidence-building measures: Increasing BWC assurance through transparency and information sharing.

In the absence of a treaty protocol or verification regime, the Biological and Toxin Weapons Convention (BWC) instituted confidence-building measures (CBMs) as a mechanism to increase confidence in compliance by enhancing transparency and mitigating ambiguities regarding states parties' biological activities. While a promising tool to support treaty compliance, low participation, concerns regarding the completeness and accuracy of CBM submissions, a dearth of analysis, and restricted access to many submissions have limited CBMs' value. Through interviews with 53 international experts-38 from BWC delegations and 15 independent experts-we identified concrete opportunities to increase CBMs' value while mitigating the burden on states parties.

Group-based trajectory models of integrated vaccine delivery and equity in low- and middle-income countries.

Background: Integrated vaccine delivery - the linkage of routine vaccination with provision of other essential health services - is a hallmark of robust primary care systems that has been linked to equitable improvements in population health outcomes.

Methods: We gathered longitudinal data relating to routine immunization coverage and vaccination equity in 78 low- and middle-income countries that have ever received support from Gavi, the Vaccine Alliance, using multiple imputation to handle missing values. We then estimated several group-based trajectory models to describe the relationship between integrated vaccine delivery and vaccination equity in these countries.

Post-epidemic health system recovery: A comparative case study analysis of routine immunization programs in the Republics of Haiti and Liberia.

Large-scale epidemics in resource-constrained settings disrupt delivery of core health services, such as routine immunization. Rebuilding and strengthening routine immunization programs following epidemics is an essential step toward improving vaccine equity and averting future outbreaks. We performed a comparative case study analysis of routine immunization program recovery in Liberia and Haiti following the 2014-16 West Africa Ebola epidemic and 2010s cholera epidemic, respectively.
