Vax has been chosen as the word of the year by lexicographers at the Oxford English Dictionary, OED.
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.
OED senior editor Fiona McPherson says vax was an obvious choice as it has made “the most striking impact”.
Vax and vaxx are both accepted spellings but the form with one x is more common. Use of the word pandemic has also increased by more than 57,000% this year.
Oxford Languages and Collins each decide their own word of the year, and in 2020 Collins chose “lockdown”.
