No economic analyses were found in India, Russia or Taiwan. Even among the published economic studies, data gaps remain. Of the two cost-effectiveness studies in Chile [54] and [55] respondents noted the studies are missing the cost of illness for a patient with buy IPI-145 hepatitis A, and that they were suspicious of economic studies sponsored by pharmaceutical companies. We also found that neither models used Chilean cost data, and instead relied on US and European costs of hepatitis A. The 2010 economic model published by the South Korean Centers for Disease Control
did not include detailed data on incidence by severity of hepatitis A cases and only reported per unit costs
for different services, leaving gaps in costs of hepatitis A in South Korea [56]. While economic data are important, respondents cautioned that it is not the sole decision maker. A vaccine PR-171 supplier manufacturer in India noted that economic data are “not the only issue as India looks at several other impact factors such as infant and maternal mortality.” In Mexico, a government official noted: “The introduction of the vaccine could be more costly than the disease itself. For example, pneumococcal vaccine was controversial at one time because of the cost. One study showed that it wasn’t cost-effective, but it was still introduced because of the number of deaths and cases reported. We identified 14 barriers and facilitators to adopting the hepatitis A vaccine by comparing those discussed in the literature with those described in interviews by country. Fig. 2 presents these barriers/facilitators and whether each was discussed in the literature and/or interviews. In general we found a large gap between barriers
and facilitators for adoption perceived by stakeholders compared to those discussed in policy papers. The importance of political support from government leaders and the role of elections were brought Electron transport chain up as a barrier or facilitator in interviews in every country (e.g. “this is an election year and it is not good to introduce anything that costs money.”), but were not mentioned in the literature. The interviews also discussed the priority for this vaccine vis-à-vis other vaccines and mentioned global or local recommendations on vaccine adoption, which were rarely discussed in the literature. A Mexican government official noted, “There are many other needs for the country and the [Ministry of Health] spends large sums of money on immunization. It is the money that is the problem, it is not available.
