      [CLS]A country's Vaccine Alliance (GAVI) eligibility is indictivate of
      accelerated adoption of the Hub vaccine.[SEP]Accelerating Policy Decisions
      to Adopt Haemophilus influenzae Type b Vaccine: A Global, Multivariable
      Analysis BACKGROUND Adoption of new and underutilized vaccines by national
      immunization programs is an essential step towards reducing child
      mortality. Policy decisions to adopt new vaccines in high mortality
      countries often lag behind decisions in high-income countries. Using the
      case of Haemophilus influenzae type b (Hib) vaccine, this paper endeavors
      to explain these delays through the analysis of country-level economic,
      epidemiological, programmatic and policy-related factors, as well as the
      role of the Global Alliance for Vaccines and Immunisation (GAVI Alliance).
      METHODS AND FINDINGS Data for 147 countries from 1990 to 2007 were
      analyzed in accelerated failure time models to identify factors that are
      associated with the time to decision to adopt Hib vaccine. In
      multivariable models that control for Gross National Income, region, and
      burden of Hib disease, the receipt of GAVI support speeded the time to
      decision by a factor of 0.37 (95% CI 0.18-0.76), or 63%. The presence of
      two or more neighboring country adopters accelerated decisions to adopt by
      a factor of 0.50 (95% CI 0.33-0.75). For each 1% increase in vaccine
      price, decisions to adopt are delayed by a factor of 1.02 (95% CI
      1.00-1.04). Global recommendations and local studies were not associated
      with time to decision.CONCLUSIONS This study substantiates previous
      findings related to vaccine price and presents new evidence to suggest
      that GAVI eligibility is associated with accelerated decisions to adopt
      Hib vaccine. The influence of neighboring country decisions was also
      highly significant, suggesting that approaches to support the adoption of
      new vaccines should consider supply- and demand-side factors.
