Why is aviation being singled out? If there is no vaccine then other elements of existence will be far more challenging.
This current fear mongering is so very remonisant of AIDS all those years ago with experts everywhere shooting their mouths off.
The reality is no one really knows what is the future and these 'experts' are just getting their 5 minutes of fame and too many people are being taken in by them.
I still feel the medicine is worse than the disease but that's only my opinion based upon the same lack of facts as the 'experts'!
Now off for another gin before another 'expert' tells us that is bad for us!!
Cheers
The key is to become an immunologically aware population. This isn't the same a herd immunity, which stops it from transmitting. What is relies on is the most people have had some exposure to the disease or a closely related one. This keeps the R0 down and also tends to lessen the severity. This is what we see for epidemic influenza, and even some pandemic influenza. There is some evidence that recent exposure to 2 of the endemic coronavirus common cold variants this year has reduced the severity of SARS-CoV2 infections, and may in some cases have prevented a small number of people from having any symptoms. Two problems with this, it is likely we will still have 'bad' years, and these could be very bad. Think flu in 2009, and we are nowhere near this point in any large population. For the UK, to get to a natural Rt of less than one right now, assuming R0 was 2.5 would have required nearly 30 million cumulative infections at the beginning of March. With ~30,000 cases then the R0 would have had to have been ~6-10, which is Mumps range.
