Several inactivated virus vaccines exist for COVID-19. SinoVac/CoronaVac.[1] Sputnik-V.[2] Janssen.[3] (The Johnson and Johnson vaccine.) None are as effective as the messenger RNA vaccines at preventing symptomatic illness, although they're pretty good at preventing death.
All three are easier to store and transport than the mRNA vaccines, as well as being one-shot vaccines. There's a political problem - they're seen as inferior vaccines for poor people, at least in the US.
