Social inequalities in hostility toward vaccination against Covid-19

Spire, A.; Silberzan, L.; Bajos, N.; group, The EpiCov study

In recent decades, France has appeared as a country particularly hostile to vaccination in general. When asked in November 2020 about the intention to take the Covid-19 vaccine, the French public showed, once again, reluctance. Therefore, France appeared as an ideal case study to analyze whether the hostility toward the Covid-19 vaccine has its own reasons or whether it is related to the reluctance to the principle of vaccination itself. Our objective was to determine the specificity of the social determinants of the intention to get the Covid-19 vaccine. Thanks to the use of a large random sample of the general population in France (86,000 individuals), the reluctant to Covid-19 vaccine could be clearly distinguished from the hesitant and the convinced, and thereby thoroughly analyzed. Our analysis highlighted a gendered reluctance toward vaccination in general but even more so regarding vaccination against Covid-19. It might refer to women being more concerned about the possible effects of an injection in their body, especially at the age of maternity and a differentiated socialization making them more sensitive than men to long-term risks and more apprehensive toward rapid technological change. We also found that people at the bottom of the social hierarchy, in terms of level of education, financial resources, and immigration status, were more likely to refuse the Covid-19 vaccine. Nevertheless, this reluctance was less prominent than for vaccination in general, reflecting the actual spread of the epidemic in various social milieux. Finally, our analysis showed that trust in the government's actions was significantly associated with reluctance toward the Covid-19 vaccine, even more than toward vaccination in general. Specific campaigns should be thought beforehand to reach women and people at the bottom of the social hierarchy to avoid furthering social inequalities in terms of morbidity and mortality.
