Using cross-country data on gross domestic product and national expenditure on vaccines, we estimate and compare the income elasticity of vaccine expenditure and general curative healthcare expenditure. This study provides the first evidence on the national income elasticity of vaccination spending. Both fixed and random effects models are applied to data from 84 countries from 2010 to 2011. The income elasticities for healthcare expenditure and vaccine expenditure are 0.844 and 0.336, respectively. Despite vaccines' high cost-effectiveness, the national propensity to spend income on vaccines as income increases lags behind general health care. The low income elasticity of vaccine spending means that relying on economic growth alone will provide an unacceptably slow trajectory to achieving high vaccine coverage levels.

利用国内生产总值和国家疫苗支出的跨国数据，我们估算并比较了疫苗支出和一般治疗性医疗支出的收入弹性。本研究首次提供了有关疫苗接种支出国民收入弹性的证据。固定效应模型和随机效应模型均应用于2010年至2011年来自84个国家的数据。医疗支出和疫苗支出的收入弹性分别为0.844和0.336。尽管疫苗具有高成本效益，但随着收入增加，国家将收入用于疫苗的倾向落后于一般医疗保健。疫苗支出的低收入弹性意味着仅依靠经济增长来实现高疫苗接种覆盖率的轨迹将慢得令人无法接受。版权所有© 2015约翰·威利父子有限公司。
