Background To encourage Covid-19 vaccination, France introduced during the Summer 2021 a ‘Sanitary Pass’, which morphed into a ‘Vaccine Pass’ in early 2022. While the sanitary pass led to an increase in Covid-19 vaccination rates, spatial heterogeneities in vaccination rates remained. To identify potential determinants of these heterogeneities and evaluate the French sanitary and vaccine passes’ efficacies in reducing them, we used a data-driven approach on exhaustive nationwide data, gathering 141 socio-economic, political and geographic indicators. Methods We considered the association between vaccination rates and each indicator at different time points: before the sanitary pass announcement (week 2021-W27), before the sanitary pass came into force (week 2021-W31) and 1 month after (week 2021-W35) and the equivalent dates for the vaccine pass (weeks 2021-W49, 2022-W03 and 2022-W07). Results The indicators most associated with vaccination rates were the share of local income coming from unemployment benefits, overcrowded households rate, immigrants rate and vote for an ‘anti-establishment’ candidate at the 2017 Presidential election. These associations increase over time. Consequently, living in a district below the median of such indicator decreases the probability to be vaccinated by about 30% at the end of the studied period, and this probability gradually decreases by deciles of these indicators. Conclusions Our analysis reveals that factors related to poverty, immigration and trust in the government are strong determinants of vaccination rate, and that vaccination inequities tended to increase after the introduction of the French sanitary and vaccination passes.

“…To improve the representativeness of our sample, we applied survey weights in all the analyses to adjust the sample distribution to the respective young adult population in each country by age, gender, and province/region of residence (see Ref [ 43 ] for more details). To account for this survey design, weighted Chi-square tests using Rao–Scott second-order correction were performed to identify differences in the response distribution between groups of changes in alcohol use (i.e., no change, decrease, and increase) [ 44 ].…”

While the COVID-19 pandemic impacted young adults’ alcohol use patterns, little is known about how changes in alcohol use may differ across different settings. Our objective was to identify and compare factors associated with changes in alcohol use among young adults in Canada and France during the first year of the COVID-19 pandemic. We conducted an online cross-sectional survey in October–December 2020 with young adults aged 18–29 (n = 5185) in Canada and France. In each country, weighted multinomial logistic regressions were performed to identify factors associated with self-reported decrease and increase in alcohol use separately (reference: no change). Respectively, 33.4% and 21.4% reported an increase in alcohol use in Canada and France, while 22.9% and 33.5% reported a decrease. Being 25–29 was a predictor of decrease in Canada, while living away from family was associated with an increase in France. In both countries, participants were more likely to report an increase if they reported depressive symptoms, smoking tobacco, or cannabis use. Conversely, those who had been tested for COVID-19 and those who were highly compliant with COVID-19 preventive measures were more likely to report a decrease. Efforts are needed to develop alcohol use interventions for young adults, including in ways that prioritize those with mental health challenges.

The French sanitary pass led to an increase in vaccination rates in France, but local heterogeneities in vaccination rates remain. To identify potential determinants of these heterogeneities and how the French sanitary pass influenced them, we used a data-driven approach on exhaustive nationwide data, gathering 181 socio-economic and geographic factors. Our analysis reveals that, both before and after the introduction of the French sanitary pass, factors with the largest impact are related to poverty, with the most deprived areas having greater than 10 times the odds of being among the districts with lower vaccination rates.
