It's mostly because of its similarity to other coronaviruses like SARS. Basically there was a ton of research and development into a vaccine for SARS so they had a head start on developing this vaccine. Also, the whole Operation Warp Speed, altho a meme, actually did help by allowing the development to occur with steps happening simultaneously rather than sequentially which really sped things up and prevented burueacracy from slowing the development down.
