The comparative docility of infectious diseases like smallpox has contributed to a degree of complacency about the magnitude of the risks of refusing vaccination. When an epidemic actually begins, people quickly change their minds, and demand the rapid production and distribution of vaccines.
天花等传染病不温不火助长了人们的自满情绪，导致对拒绝接种后果认识并不充分。疫情爆发时人们迅速改变想法，要求快速完成疫苗生产和流通。这或许是件好事，但这并不现实。
