"The average person gets 3 vaccines a year" factoid is actually just a statistical error. The average person gets 1 vaccine per year. Vaccine Georg, who lives in Germany and gets 89 vaccines a year, is a statistical outlier and should not have been counted.
I did the math. He got an average of 7-8 vaccines per month, which came out to about 89 per year for the 29 months he's been doing this.
