Christine Clements (December 26, 1979 – August 22, 2023), professionally known as Vaccine, was an American dubstep record producer based in California. She was one of the first women signed to a dubstep related record label (Hotflush Recordings), which was up until then a genre whose producers were almost entirely male.

Before she started producing, Clements promoted other people's music.

Vaccine's style has been recognised as being considerably more melodic and ethereal, with XLR8R magazine noting her "subtle melodies and echoed vocals", as well as stating that "(Vaccine's) constructions aren't necessarily main floor rave fodder, but rather, comedown music for a 6 a.m. all-back-to-mine", as well as mentioning "jittery electronic elements with gothic ambient nuances."

Clements was a self-described Skinny Puppy and Portishead fan. Her influences were "Nine Inch Nails, Dom & Roland, Skinny Puppy, The Prodigy, Technical Itch, Sasha and Digweed, Future Sound of London, Akira Yamaoka, Helios, Harold Budd, Surgeon, Zero 7, Portishead, Massive Attack, Tricky, friends, lovers, label mates, colors, sounds, places, feelings."

In 2014, she released the Decryption EP on ASC's label, Auxiliary Transmissions.

Clements died on August 22, 2023, at the age of 43.
