They absolutely are.
I agree T&T is vital for future viruses - and for understanding community transmission and mutations of the current one - but sorry, what you've said there in bold is nonsense. The vaccines are clearly our best defence against COVID-19.
Vaccines are going to become an annual, or at least regular thing for a lot of the population so surely the vaccine boosters will adapt over time to counter changes to the virus.
We need to wait a bit longer, but once we have a lot more people vaccinated then we need to open up most of the economy. If everything goes to plan then there's no reason for big restrictions come the summer, and the general public won't understand it either.
