Which is more common, inoculation or vaccination?

We are ライズONE,Oita,Japan.

We’re the strongest in letting the students get high scores


get them in the 10% in the test. My nickname is ER.

do you know the word “inoculation” or “vaccination” ?

If you inject it, it’ll prevent you from getting worse when you catch the flu.

We, ライズ, are supposed to inject it because we must not give the flu to our students,

especially not to the students for entrance exam.

By the way which is common in English?

“Vaccination” is more common than “inoculation”

“Inoculation” seems to be a technical word doctors or nurses use.
