My guess is it’s between the two of us.
While on active duty ALONE I’ve had the Japanese encephalitis vaccine, both the Hep A and Hep B series, annual flus for 16 years, yellow fever, typhoid, meningiococcus, smallpox, six anthraxes, four MMRs, one polio, two TDaPs, and I’m sure a partridge in a pear tree. That’s what I can remember off the cuff.
Plus all my vaccines as a kid. And flu vaccines in those civilian years between my enlisted and commissioned time.
The worse ones were typhoid, yellow fever, and JEV.
