Microbiologist / Virologist here:
Dig no further, here's the interpretation.
- The vaccine is a new style of vaccine, a new way to get your immune system to better fight the virus itself. When they say it "works perfectly" they mean the new style seems to be making the immune system do exactly what we want it to do. We didn't know if the new method would really work in the real world, and it seems that it is working exactly as we had hoped.
That doesn't mean it protects you perfectly though. Basically we've given our immune system the big guns, and they seem to be laying waste to the virus, but ultimately you can never kill it all and some will survive and potentially make you sick/symptomatic.
- To that same end, the scientists working on the vaccine are clarifying that we will not fully rid ourselves of the virus. What the vaccine will do is turn Covid-19 into a yearly recurring thing like the flu (endemic), low enough numbers that we don't need to wear masks and social distance, but still present annually and some people will still get sick from it every year.
(EDIT: Listen to this
RadioLab (start at 54:30) to better understand how today's Flu is actually a version of the Spanish Flu from 1918, it's an insane story and worth the listen... basically that pandemic never really ended and Covid-19 is unlikely to go away completely either)
- Putting on my epidemiology hat, the final takeaway is that the vaccine will be available earliest Spring 2021, and then there is the massive public health challenge of administering the vaccine to the world. They don't quote timelines for that phase, but my educated guess is 6 months.
- Final Personal Opinion: Trust the Oxford team and their messaging. They have already shown that they will slow things down in order to make sure they get it right. They're following globally accepted processes for developing safe and effective vaccines and are being transparent and objective regardless of whether the news is good or bad. This could certainly change, there's a looooong way to go, but for now my assessment is that they are very trustworthy at this stage.
