Despite that there are still controversies about whether people should take second booster, the fourth shot, or not, still my wife and I took the injection of the fourth injection of BNT(Pfizer) this afternoon at NTU hospital.  

Unlike previous three easy-to-get shots in the States, the injection we received in NTU Hospital seems a little complicated in procedure, partly because of its drones of patients and workers.  But we got some awards like we did in the States: a TWD500 coupons of some convenient store for each senior over 65, and two boxes of self-testers.

Next thing we need to worry about is any adverse reaction after injection.  But so far so good.
