Which vaccines are more promising in terms of longer term immunity? Bloomberg reports CanSino one seems to be better than Moderna on that and it only requires one shot.
The Oxford vaccine is the front runner. They're doing several Phase III trials right now, and people are taking that to be a good sign - that they want to present plenty of evidence of efficacy.
The downside is that it's two doses and you're still going to get COVID-19. It's just that the effects are far less severe.
I think we're at about "vague hunch" certainty on how well these vaccines will work in the field.
That breaks the site guidelines, and we ban accounts that do that, so please don't. Your comment would be just fine with the link and the second sentence.

In places with good contact tracing, they should mostly be able to keep it at near zero after that point by tracing and self-quarantine, occasionally needing to use the vaccine on a whole city if you find that you had a super-spreader event.
In places without good contract tracing, it would be similar except the threshold at which you need to vaccinate the city would be lower.
This point never came for influenza anywhere, why would you think it will come for COVID19, a much more contagious and invisible in many more cases virus?
They are anti-vaxxers, yes, so no wonder that they could technically get measles, but where did it come from? It was completely irradicated because most people had the immunity. The virus should have died off and disappeared from the face of the planet. And yet here were are. There must mechanisms for viruses to survive this.
We’ve had a measles vaccine for three generations, we still have the measles.
We’ve had a polio vaccine for three generations, polio is not eliminated.
Seriously, though, i wonder why would Russia be developing coronavirus vaccine if most people these days die there from "atypical pneumonia" and not from coronavirus ... at least if one is to believe the official info.
