Lack of access to COVID-19 vaccines could be a greater threat than vaccine hesitancy in low-income and conflict nations: the case of Yemen

Abstract

Background

Vaccine hesitancy and vaccine inequity are two major hurdles towards achieving population immunity to COVID-19. Although several studies have been published on vaccine hesitancy among numerous populations, there is inadequate information on any potential correlation between vaccine acceptance and lack of access to vaccines. Our cross-sectional study in a low-income country aimed to fill this gap.

Methods

We conducted a nation-wide cross-sectional survey among the general population in Yemen, a low-income conflict country. Participants from all the provinces in Yemen were included in the study. We evaluated factors influencing agreement to accept a COVID-19 vaccine and any potential correlation between vaccine hesitancy and lack of access to vaccines.

Results

Overall, 50.1% of the 5329 respondents agreed to accept a COVID-19 vaccine. Only 39.9% of the participants agreed to having access to a COVID-19 vaccine, with females indicating lower access than males. Potential determinants of vaccine acceptance included being male, updating self on the development of vaccines against COVID-19, opinion about severity of COVID-19, anxiety about contracting COVID-19, concerns about the safety of COVID-19 vaccines and lack of access to vaccines.

Conclusions

our results indicate that the immediate threat in Yemen towards achieving population immunity is the severe shortage and lack of access to vaccines, rather than vaccine hesitancy.
