Thankful Day #17

Thankful Day #17: I am thankful for vaccines. We have forgotten, in the affluent Western world, what it is like to suffer epidemics of polio (which paralyzed children), diphtheria (which choked victims to death) and measles (which caused brain damage, seizures and death). In my career so far, epiglottitis, a killer of infants, has become rare due to vaccination. The hero pictured here is Jonas Salk, who developed the killed polio vaccine, rendering this once-common disease almost unheard of.
