Government-issued vaccine passports convinced a minimal number of people to get COVID-19 shots, accounting for less than 1 percent of people in Quebec and Ontario, according to a peer-reviewed study.
The effect on vaccine uptake in the vulnerable elderly group of those over age 60 was even lower; only 0.1 percentage points got a shot following vaccine passports. The study noted that this was the most vaccinated age group.
Quebec and Ontario, the largest, most populated provinces, were among the first to announce vaccine passports in September 2021. The study notes that provincial governments said the policy was to “reduce SARSCoV-2 transmission,” but adds that the “evidence on their effectiveness at incentivizing” COVID vaccination uptake “remains limited.”
The study considered vaccinated numbers before vaccine passports were made mandatory for non-essential activities in Quebec and Ontario and simulated what the results would have been if passports had not been implemented.
Among young people aged 12 to 17, the least likely group to get COVID shots in both provinces, the study said passports increased the rate of vaccination by 2.3 percentage points in Quebec and 1.3 percentage points in Ontario.
