• [Pre-print, not peer-reviewed] A SIR model simulating the impact of vaccine passes or passports on SARS-CoV-2 dynamics found that different restrictions for passholders and unvaccinated individuals can result in a wide variety of epidemic trajectories, some of which may introduce new waves of infections. For example, while passholders may have fewer restrictions initially compared to the rest of the population, the authors assumed that immunity would wane over time, necessitating re-vaccination or further restrictions among vaccinated persons. The authors concluded that lowering restrictions for vaccine passholders would only be effective in the context of strict restrictions for other members of the population.
