覚え方のコツ Memory Tip
原形 vaccinate の語末 e に -d を付けた過去分詞で、/t/ の後なので語尾は /ɪd/ と発音します。形容詞では vaccinated children や vaccinated dogs のように「接種済みの人・動物」を修飾します。vaccine、vaccination と語族でまとめ、接種という行為より完了後の状態に注目しましょう。
Vaccinated is the past participle of vaccinate. Because vaccinate ends in silent e, add only -d; after the /t/ sound, the ending is pronounced /ɪd/. Link it with the familiar word vaccine and picture a completed medical record: a vaccinated child or vaccinated dog has already received the relevant shot or dose. The adjective emphasizes the resulting status, while vaccination names the procedure or program. Also remember that vaccinated does not automatically mean completely immune; it specifically states that a vaccine has been administered.

vaccinated の語源・成り立ち Etymology
ラテン語 vacca（雌牛）に由来。18世紀にジェンナーが牛痘（cowpox）を用いて天然痘予防法を開発したことから、vaccine（ワクチン）が生まれた。関連語：vaccine, vaccination。牛が語源という意外な由来が印象的。
Vaccinate belongs to the same family as vaccine and vaccination. These words ultimately derive from Latin vacca, meaning “cow,” because Edward Jenner's early method of protection against smallpox used material associated with cowpox. The scientific term was later broadened to cover immunization against many diseases. Vaccinated is formed from vaccinate by adding -d to the final e and functions both as a past participle and as an adjective describing vaccination status.
