It's not really how long the vaccine works, that's not how it works. It's how long until the disease, virus or infection mutates to a new strain and you can be re-infected again at that time, which means you need another dose that has also changed with the mutation. The common flu for instance is 1 year. Some other viruses/diseases/infections are a few months, some are several years...others never mutate.
