Private demand for cholera vaccines in Beira, Mozambique

Social and cultural determinants of anticipated acceptance of an oral cholera vaccine prior to a mass vaccination campaign in Zanzibar

“…Other studies highlight the problem of cost as a barrier to use of desired OCVs. [24][25][26] If free vaccination becomes possible for cholera control in Zanzibar, findings from this study of high community demand for a free OCV suggest it will be effective. This demand for an accessible vaccine complemented demand for classical preventive interventions, such as improved infrastructure, better services and health education from the government.…”

“…23 This study aimed to assess social and cultural determinants of anticipated oral cholera vaccine acceptance prior to a mass vaccination campaign in a peri-urban and a rural community of Zanzibar. Because of the reported high awareness of cholera in the study communities, 23 it was hypothesized that anticipated acceptance of the free vaccine would also be high, and that determinants of anticipated acceptance would not only include sociodemographic and economic characteristics, especially for high-priced vaccines, [24][25][26] but also socio-cultural features of illness. Social and cultural determinants of anticipated OCV acceptance were investigated with regard to the OCV at no cost, and at three distinct price levels.…”

Giving Stated Preference Respondents “Time to Think”: Results From Four Countries

“…Although some respondents had experience with older, less effective versions of these vaccines, the improved "next generation" cholera or typhoid vaccines were generally unavailable in these countries except in limited trials designed to evaluate the vaccines' protective effectiveness, during which they were distributed free of charge (Jeuland et al 2009c). Because of this unavailability of "next generation" vaccines, we relied on stated preference techniques to measure household demand (Canh et al 2006, Lucas et al 2007, Islam et al 2008, Kim et al 2008. This information was then used to evaluate the economic attractiveness of investments in these vaccines using both benefit-cost and cost-effectiveness techniques , Cook et al 2009b, Jeuland et al 2009b.…”

“…Although exact multivariate modeling specifications differed somewhat between field sites (see Cook et al 2007, Lucas et al 2007, Islam et al 2008 for more details), our approaches were similar. We analyzed respondent demand from the BC exercise (Kolkata and Matlab) using a probit model, and analyzed PC data using both OLS and an interval regression model (Cameron and Huppert 1989).…”

“…Although the research designs differed somewhat, all four studies used the same general split-sample approach to examine the effect of time to think on both single binary discrete choice (India, Bangladesh, Mozambique) and a sequence of multinomial choice (Vietnam) responses 2 . Although the full results from these studies have recently appeared in the literature (Cook et al 2007, Lucas et al 2007and Islam et al 2008, these papers were not focused on the examination of the effect of TTT (with the exception of Cook et al 2007). Furthermore, because of their public health and development focus, they may not have come to the attention of many SP practitioners, many of whom are environmental economists.…”
