What would happen if the vaccination programme for diphtheria was cancelled?
If the vaccination program for diphtheria was halted, we would see a resurgence of the disease. Corynebacterium diptheriae is the causative organism (a bacteria) of diphtheria which affects mostly young people. Before the advent of vaccination, an estimated 15,000 people died every year in the U.S. After the vaccination program was implemented, the fatalities dropped to less than one every year.
