How did sinovac develop an inactivated vaccine faster than the the new rna vaccines?

If one of the main advantages of rna/vector vaccines is faster rollout how did sinovac develop a traditional inactivated vaccine faster or at least almost the same rate?

Do you have a citation for the "mRNA vaccines have faster rollouts?"  They can be fast, but production differences are not incredibly significant. 

The covid-19 vaccines are the first widescale rollouts for mRNA vaccines, so there's no real historical precedent.

The sinovac route I'd argue is faster. Grow up virus, UV/fornalin/whatever inactivate, assure inactivation, package and inoculate.
