Does the COVID-19 epidemic need a COVID-19 vaccine to completely end it?

It should be necessary. After all, the new coronavirus is mutating too fast and it is global. The first is to improve the body's own immunity, so that the virus will not defeat humans so easily. Second: Get vaccinated in advance to prevent viruses in advance and prevent virus outbreaks and infections. Third: Everyone should practice good personal hygiene, wear a mask when going out in densely populated areas, and wash hands in time after touching dirty items.
