Vaccine-preventable diseases (VPD) are responsible for a significant portion of mortality across the life course in both low-income countries and in medium- and high-income countries. Yet, countries are consistently below the adult influenza vaccination targets, with rates in recent times even falling in some areas. (1) The study Towards Ending Immunization Inequity seeks to understand the various factors that contribute to the accessibility and effectiveness of vaccine-related messages and campaigns including the effects of social determinants, with the knowledge that these opportunities for communication represent a unique policy lever to improving uptake rates of vaccination in the most at-risk communities. (2) To address this knowledge gap, a 3-phase mixed-methods study was conducted including a preliminary scan of existing vaccine schedules and NITAG recommendations, focus groups and a cross-sectional survey. (3) Study results indicated that social determinants play a key role in an individual's knowledge of vaccine-related information including types of vaccines available, vaccination gateways, vaccine recommendations and vaccine safety. (4) However, knowing that social determinants can influence uptake rates does not readily create opportunities and entry points for governments to implement tangible actions. An accessible entry point to reducing and ending immunization inequity is through changes in public health messaging to reach those who are currently unreachable.
疫苗可预防疾病(VPD)在低收入国家以及中高收入国家的全生命周期死亡中占很大比例。然而,各国始终未达到成人流感疫苗接种目标,近期一些地区的接种率甚至还在下降。(1)《迈向消除免疫不平等》这项研究旨在了解促成疫苗相关信息和宣传活动的可及性与有效性的各种因素,包括社会决定因素的影响,因为人们知道这些沟通机会是提高最脆弱社区疫苗接种率的一项独特政策杠杆。(2)为填补这一知识空白,开展了一项分三个阶段的混合方法研究,包括对现有疫苗接种计划和国家免疫技术咨询小组建议进行初步梳理、焦点小组讨论以及横断面调查。(3)研究结果表明,社会决定因素在个人对疫苗相关信息的了解方面发挥关键作用,这些信息包括可用疫苗类型、接种途径、疫苗建议以及疫苗安全性。(4)然而,虽然知道社会决定因素会影响接种率,但这并不能轻易为政府创造实施切实行动的机会和切入点。减少并消除免疫不平等的一个可及切入点是通过改变公共卫生宣传,以覆盖目前无法触及的人群。
