That's unrealistically optimistic. The best case scenarios I've heard have it being deployed to healthcare workers late this year, and then hopefully be made available across the globe to approach the herd immunity threshold by the end of 2021, at least in some countries/communities. End of 2021 is an optimistic timeline to be talking about "major relief", and that's assuming no one messes with vaccine availability... Until then, we all need to take this extremely seriously and do everything we can to prevent spread.
