<upd_detl>In the medical sense, this carries the specific nuance of it being from a vaccine and not another kind of medical treatment.</upd_detl>

<upd_detl>Suggest [stat1], well worth learning anyway.

I failed to recognize this term when getting a corona booster shot today in Shinjuku.　Ended up saying something embarrassing (so my judgement here is biased, if you have a better source for current statistics).  It was part of the quick Q&amp;A with a nurse before you get the shot.  Objectively perhaps 1/3rd to 1/2 as common overall in current media vs. 副作用 as far as I can see.

Coronavirus vaccines seems to have wildly increased the commonness of this term since the ngram days(both in direct application and anti-vax movements). I imagine that contributed to the gloss improvements in 2021/2022.</upd_detl>
<upd_refs>副作用, for comparison, is the main "side effect" entry, and is [ichi1,news1,nf06]

~0.5 ~ 2 posts/minute for 副反応. Maybe 1/3rd of 副作用
