COVID-19 Vaccine Survey, Survey 1 2021 - South Africa

Abstract
---------------------------

The COVID-19 Vaccine Survey (CVACS) is a South African national panel study of individuals initially unvaccinated against COVID-19. CVACS is implemented by the Southern Africa Labour and Development Research Unit (SALDRU) based at the University of Cape Town. The same respondents are interviewed twice, a few months apart, in 2021 and then 2022, to gather information about their attitudes, beliefs and intentions regarding COVID-19 vaccination. The purpose of CVACS is to collect high quality, timely, and relevant information on facilitators and barriers to COVID-19 vaccine uptake - including vaccine hesitancy and access constraints - to contribute to the development of data-driven campaigns and programmes to increase COVID-19 vaccination uptake in South Africa.

Geographic coverage
---------------------------

CVACS was not designed to be, and should not be used as a prevalence study. The data cannot be considered to be nationally representative of all unvaccinated individuals in South Africa.

Computer Assisted Telephone Interview [cati]

Research instrument
---------------------------

A single survey instrument was administered for CVACS Survey 1 using computer-assisted telephone interviews (CATI). The CVACS questionnaire was translated into all South African languages and interviews were conducted in the preferred language of the respondent. The realized Survey 1 sample consisted of 3510 individual interviews, all of whom self-reported that they were unvaccinated for COVID-19. Most of the survey questions collected individual-level data, with some household level data also collected through the individual questionnaire.

摘要
---------------------------
COVID-19 疫苗调查 (CVACS) 是一项针对最初未接种 COVID-19 疫苗的南非全国性面板研究。CVACS 由位于开普敦大学的南部非洲劳动与发展研究单位 (SALDRU) 实施。相同的受访者于 2021 年和 2022 年分两次接受访谈，间隔数月，以收集有关他们对 COVID-19 疫苗接种的态度、信仰和意图的信息。CVACS 的目的是收集高质量、及时且相关的信息，关于促进和阻碍 COVID-19 疫苗接种的因素——包括疫苗犹豫和获取限制——以促进数据驱动的宣传活动和项目的发展，从而提高南非的 COVID-19 疫苗接种率。
地理覆盖范围
