Vax has been chosen as the word of the year by lexicographers at the Oxford English Dictionary (OED).Vax被《牛津英語詞典》評為年度詞匯。
Words related to vaccines have spiked in frequency in 2021 due to Covid, with double-vaxxed, unvaxxed and anti-vaxxer all seeing a surge in use.由於新冠肺炎疫情，2021年與疫苗相關的詞匯更加頻繁出現，“接種過兩劑疫苗的”、“未接種疫苗的”和“反對疫苗人士”這些詞匯的使用頻率驟增。
OED senior editor Fiona McPherson says vax was an obvious choice as it has made "the most striking impact".《牛津英語詞典》高級編輯菲奧娜·麥克弗森稱，“VAX”是最合適的選擇，因為這個詞的“影響是最大的”。
"It goes back at least to the 1980s, but according to our corpus it was rarely used until this year," she said.她說：“Vax至少可以追溯到20世紀80年代，但根據我們的語料庫，直到今年人們才開始大量使用它。”
"When you add to that its versatility in forming other words, it became clear that vax was the standout in the crowd."“再加上vax還能組成很多詞匯，顯然它就在眾多詞匯中脫穎而出了。”
Vax and vaxx are both accepted spellings but the form with one x is more common.Vax和vaxx這兩種拼寫都可以使用，但vax更常見。
