I've read reports which suggest a vaccine is a very long way off, if its even possible to create. I suspect more accurate testing with faster results is more likely though you could test negative on departure and turn out positive on arrival. It may get to a point where the economy can suffer no more and everything opens, we stop counting and life goes on for most. Parts of Europe are already open for travel without the need to isolate and they're still receiving consistently higher daily infections, same with the UAE and Qatar for example. Are we just delaying the inevitable?
The current thinking is that:
- A vaccine for this virus has never been created previously
- There are very 'good' results in the Oxford trials to date
- The thinking around timeframe is the very very optimistic result would be 12-18 months (from now)
- Very few scientists (actual researchers, biology and virology) that I've directly talked to have any confidence that timeframe is 'real' because it would be years faster than anything ever achieved before - but it isn't actually impossible. Just improbable
- The effectiveness of any vaccine is still being debated - e.g. 40% effectiveness (like cold/flu now) compared to 97% effective (for MMR).
When you make a statement about the 'economy' can suffer no more - please keep in mind it isn't a real person. It doesn't actually suffer like a real person. It can't actually die either. The people aren't ever coming back (after they have died) and some of there will be very severely damaged even when they have survived.
To put it in prosaic terms, the US has already shown the way around putting their economy first. ~150K dead people so far is the price paid and it will be a lot more.
I don't suggest there are any easy answers to this (and to tie this back to the question about when international flights resume) but I am always reminded of one of the most power ads I have seen about reducing the road toll in NSW. 50 people a year dying was seen as reasonable by an average guy in NSW until the 50 people were made of his own family and friends. And at that point zero deaths was much more palatable.
I can't wait to be able to travel overseas again but I can't think of anyone I am willing to have die to let me do that. I can think of a few people that we might be better off without on this planet and may be willing to trade them for my ability to have a job and work.. but even that requires some thought..
