The only way to ensure escape from a disease is to eradicate or contain it. A vaccine helps tremendously in that regards, but alone doesn't guarantee eradication; as we have flu vaccines since the 1930s, yet the flu still remains amongst us. However, this is arguably just a result of vaccination rates; if more people took the flu seriously and were regularly vaccinated, we may have eradicated the flu by now.
Same for COVID-19. If people don't ever take this seriously enough, then I doubt we'll eradicate it. The virus is on every continent in ~120/195 of the world's countries, all of which happened in a few months, despite travel bans and quarantines setup to initial outbreak areas. To me that sounds like people need to take it more seriously and put more effort into containing this. Otherwise it looks like it'll end up being endemic just like the flu, and we may never eradicate it despite having a vaccine - as what evidence do we have that enough people will vaccinate themselves when we do have a vaccine, if people keep equating it to the flu...
