...not just against COVID-19 but also other coronaviruses

This seems improbable as coronaviruses are an entire classification of virus which include rhinovirus, the common cold virus, flu, SARS, AIDS, swine flu, etc.

No, they aren't. The Coronavidae family does not include any Rhinoviri, Influenza, HIV, or swine/avian flus. There is no specific "common cold virus"; the common cold can be caused by multiple different viri, which include some variants of Coronaviri, Rhinoviri, or RSV (and others).

There are hundreds of different coronaviri, but only a few that can infect humans: MERS-CoV, SARS-CoV, SARS-CoV-2 (Chinavirus), and four other variants which cause no more than a cold. They are minor enough to where they don't have a fancy name like the other three: 229E, OC43, NL63, and HKU1.

Not to mention they all mutate. Who’s to say what it’ll look like in five years.
