So to increase vaccination rates, Brewer sees three possible approaches. To boost vaccination rates, some health insurance companies offer financial incentives to doctors and other providers. This can decrease vaccination rates in some locations to below the necessary herd immunity percentage. Canada lacks a national immunization registry and wide variation exists across provinces, so Dubé noted the nation's vaccination rates may be underestimates. "Traditionally, most of the interventions to increase vaccination rates were aimed at enhancing access to vaccination services (reducing distance to vaccination clinics, offering vaccination during home visit, sending reminders, etc.)."
