I don't know if that's the exact dollar amount, but one thing that's clear--not only in Canada, not only in Quebec, but around the world--is that world experts fully agree that vaccination and immunization are by far the most cost-effective medical interventions that exist. The only exception might be the purification of water. Vaccines have been proven as the most cost-effective medical intervention around the world.
It's sad that today we sometimes have to defend and debate the importance of vaccine and immunization programs. To me it should not be an issue.
