The reason that there has never been a cold vaccine is because, there are at least 20 types of it that infect people, and about 200 more that are occasionally in circulation.
Covid mutates far faster than a cold virus.
It is probable that in a few months or years that the current vaccines will not work, there will probably be too many mutations to count.
