vaccine stamp

(名詞/可數) 疫苗戳記 - 蓋在護照上以示護照持有人已打過或接種過新冠病毒疫苗的戳記。

引句:
The new "vaccine stamps" would allow tourists to avoid being held up at borders if the international travel industry starts to pick up in the middle of next year as the pandemic subsides. The stamps are being considered by ministers at the Department for Transport (DfT) as a significant way to boost the aviation industry by giving a degree of certainty to travellers planning overseas holidays next summer.
