This December 2021 article reports that several dictionary publishers selected different words for that year, including “vaccine,” “vax,” “perseverance,” and “NFT.” It explains that search activity and cultural attention can influence selections. “Vax” is an informal shortening used as a noun or verb; the article is a historical report, not medical guidance.

Cultural note: The word choices and search statistics are tied to 2021. “Vax” is informal; “vaccine” and “vaccinate” suit more formal or medical contexts. A word-of-the-year label reflects a publisher’s criteria and does not settle debates about a word’s meaning or importance.

Keep exploringTwo dictionaries can choose different words for one year. The contrast between “vaccine” and “vax” also shows how formal terms get shortened in casual speech.
