Yes... Modern form of inactivated vaccines have been used probably since 1950s. It's the most simple to manufacture. Start from a virus isolate, then grow it in Vero cell-lines. Then the supernatant of the infected cells are deactivated for around two days using β-propiolactone. Then after ultrafiltration, a second time deactivation is done using β-propiolactone. Then various fillers are added and the product is bottled.
