Since you ask, Atenco (I picked diptheria because i happened to remember 2 of my grandmother's 7 siblings died in a diptheria epidemic - but I'm sure it would be easy to find similar information for other diseases for which we routinely vaccinate).
Taken from a pdf produced by the Centre for Disease Control (US federal department, AFAIK).
"Death
The overall case-fatality rate for diphtheria is 5%–10%, with
higher death rates (up to 20%) among persons younger than
5 and older than 40 years of age. The case-fatality rate for
diphtheria has changed very little during the last 50 years."
In contrast, the complication rate for the vaccine is given as CDC website again:
"Moderate Problems (Uncommon)
Seizure (jerking or staring) (about 1 child out of 14,000)
Non-stop crying, for 3 hours or more (up to about 1 child out of 1,000)
High fever, over 105°F (about 1 child out of 16,000)
Severe Problems (Very Rare)
Serious allergic reaction (less than 1 out of a million doses)
Several other severe problems have been reported after DTaP vaccine. These include:
Long-term seizures, coma, or lowered consciousness
Permanent brain damage."
So, bit of a no-brainer really. Overall death rate in a diptheria epidemic 5 to 10% (higher in small children), rate of moderate complications 1 in 14,000 (seizures), rate of severe complications less than 1 in a million.
Thing is, I'm sure your average anti-vaxxer would simply start squawking about a government cover-up at this point and claiming the CDC statistics were because they were hand-in-glove with big pharma.
