Like the methods needed to make inactivated vaccines have been in use for many years — as with the polio vaccine, hepatitis A, rabies, etc. It wasn't therefore that difficult to apply these platforms and create an inactivated COVID-19 vaccine. So the quickness of the vaccine development isn't an issue here, since every COVID-19 vaccine has undergone the necessary trials to ensure its safety and efficacy. Examples of an inactivated vaccine are Sinovac's CoronaVac, as well as Bharat Biotech's Covaxin, which recently received its EUA from the FDA.
