End of the day, if everyone and that's including young kids are vaccinated, then vaccine based travel will probably go ahead with many countries sometime next year
I'm less optimistic. If delta is 2x as transmissible as alpha, and the vaccines seem to reduce risk of infection by about half, then delta is going to spread at about the same rate amongst the vaccinated as alpha did before vaccines.
We could maybe accept that (and might have no choice), but there's a high risk that the virus will mutate to become more resistant to the vaccines and past infection and treatments faster than our our ability to counter that - because it's a numbers game, the mutations are random, but millions of people infected at any point in time, well... We shouldn't have let that happen.
Edit: aaargh - that's depressing. There's always the possibility that the next mutation might make the virus more transmissible and better at escaping immunity, but that mutation might also make it less virulent - there's no advantage to the virus in harming people, so causing less harm isn't a disadvantage. That's what generally happens with new contagious diseases - but it takes a long time. Maybe that's what happened with "Spanish Flu", or part of the story anyway. Millions were infected, then it became "seasonal flu".
I don't disagree. The trial will give a lot of data. Anti-virals, booster, young kids jabbed, and whatever we learn from here will all help.
