That for Coronavirus has had to be designed from scratch. Not only does this take longer, but more testing is needed for safety before it can be generally released for use.
The major part of the "delay" in releasing drugs is the safety testing, and this is a trade-off between the risks and the benefits. Since the benefits of an effective Coronavirus vaccine are huge, it is considered worthwhile to take a bigger risk that there might be more adverse effects to its use, rather than spending years reducing this risk (and losing the benefits).

Medical scientists began preparing for the generic type of CV (not just CV-19) 3 or 4 years ago. The China wet markets were a CV Pandemic waiting to happen. That is the REASON why they were able to get vaccines for COVID-19 faster than other disease vaccines. Then after some "pulling of teeth" with China, China gave the US and the world the new DNA print of CV-19. Then world-wide SCIENCE went into gear.
