2021.09.11 Due to the COVID-19, I went to inject Oxford-AstraZeneca (AZ) vaccine, which is the first dose for me, in the clinic with my mom today. After the vaccination at about 15:30, I was told to wait for 15 minutes to observe there was a discomfort by the nurses. I also told my mom to wait outside for preventing gathering, because there were lots of people in the clinic. After a few minutes, I got a COVID-19 Vaccination Record. About 15 minutes later, we go to the nearby pharmacy to buy some Panadol (普拿疼) caplets. When the side effects come, it could treat fever and pain. Why I choose AZ? For me, I could choose inoculate Medigen (高端) vaccine few weeks ago, but I am not sure if Medigen vaccinated people could successfully entry other countries. In my opinion, the AZ vaccinated people could have more chance to entry other countries. There are some brands of vaccine could be inoculated in Taiwan, like AZ, Pfizer–BioNTech (BNT), Medigen, Moderna (莫德納). Maybe we could get United Biomedi
