- There is a 0-10.5 in 1,000,000 risks of encephalitis from DTaP; Comparatively, there is a 1 in 20 risk of death from diphtheria; 2 in 10 risks of death from tetanus; and 1 in 20 risks of Encephalitis /1 in 1,500 risks of death from pertussis.

The risk of pneumonia from measles: 6 in 100
The risk of death from measles: 2 in 1,000
