The other day, my wife and I went to a pharmacy for the shingles shots apiece. All we had to do was making an appointment online and proceeded to the pharmacy on time to get the shots, nothing else. It was "free of charge".

It seems a good service here to get the vaccine of shingles free, when compared with the expensive charge TWD8,000 per shot in Taiwan. Actually, it is not "free of charge" for any vaccine shot here in the States. Because the pharmacy has to cheek your health insurance in addition to the medicare and ID. I think the pharmacy will claim the charge to the insurance companies, and the later will get reimbursed from your premium. Well, it is a business, not a free lunch at all. The "difference" is the insurance premium has been paid, no matter you got shot or not, while the fee for the people in Taiwan is an addtional charge out of their pockets. 

FYI, the reaction after shot is not light. My arm, where the vaccine was shot, had been sore for several days, and I also experienced fatigue and inertia for two days.
