How do we then put timelines on something we don't know? You say best case scenario mid-2021, the government says end of 2021, yet we don't know anything. There is literally nothing we know about the vaccines apart from that two of the front-runners have had to be paused because of people getting sick. One of them is still paused world-wide (J&J) and the other is still paused in the US (AZD) because the illness seems pretty severe.
And for the record, regarding phase three trials, ALL those dates have been moved.
Moderna said by september we will know something (not even a peep from them). Pfizer said they think they will have approval by October and AZD+Oxford also we should know results by September - not approval, but we should know something. Yet, absolutely nothing.
Don't get me wrong, I really, really, desperately want a vaccine, therapeutic, mass rapid testing, or anything that can speed up the global recovery and get us back on the road. I really, desperately want to see my family - as I'm sure millions do. But we need to stop living in this fantasy land by putting dates and timelines that are completely redundant until we actually know something for sure.
Furthermore, we need to realise this thing is here to stay. We need to hold the government accountable and ask them the difficult questions, such as: Why they are asleep at the wheel and letting the economy go to sh** instead of trying to find a strategy to live with this?
