These are useful words to know! They come up a lot in conversation, nowadays.
백신
Vaccine
This is the vaccine itself, the medication that you put into your body.
접종
백신접종
Vaccination
This refers to the act of getting vaccinated.
An example sentence can be seen in the news article shared by 리리! It’s also where I found this word.
예방접종
Vaccination
This is the same as 백신접종; they’re both words indicating the act of getting vaccinated. I was informed that 예방접종 carries the nuance of being used for prevention, where 백신접종 is just the vaccination itself in general.
