What is vax short for?

Where does vax come from?

While vax's origins are unclear, the abbreviation most likely traces back to the early-2000s, when the anti-vaccination movement gained steam. Instead of typing out or saying "vaccination," people began shortening the word to "vacc" or "vax" as they talked about the dangers (real and imagined) of vaccines. Since "vax" is the easiest "vaccination" abbreviation to type, it grew in popularity as Internet and smartphone usage increased.
