Sadly I think we will be stuck with this for a while yet. Vaccines will help, but there will always be those who are against vaccines and I think they will present a great threat to the general population.
Governments are not about to change how they react to outbreaks for some considerable time. The inability of the different governments to harmonize definitions, restrictions and balance between the economy and management options will ensure that not much will change over the short term.
I think it will still be around in various forms. Hopefully we can learn to live with it and maybe have vaccinations every year just as we do now with the flu vaccine.
Three out of four people so far have it right. The new norm will involve better hygene practices (till we get complacent) and annual or bi-annual vaccinations.
