Does a vaccine offer a way out?

It is fascinating that a possible vaccine is announced as producing good test results shortly after the US election. Apparently there needs to be more time to evaluate it, with a possible appeal for Regulatory approval starting before the end of this month. The method used is new, and the team developing it will need approval to go to accelerated production and roll out as the request will be before usual testing procedures are exhausted.

The company will need to file details of side effects and the results of their safety tests, as well as latest evidence on how effective it is at preventing people catching CV 19. Apparently people need to be vaccinated twice over a 3 week period to gain reasonable immunity. No-one yet knows how long the beneficial effects will last.

I have some questions about this. How willing would you be to take such a vaccine if approved soon? Should the early doses available go to the most vulnerable and to health workers at risk, as is suggested?

At what point can governments then relax their controls and allow us to return to more normal lives? As it has been the wish of many of the scientific and medical advisers of governments to use vaccines to end this crisis they should now spell out to us how long we have to wait for them to be satisfied that enough vaccine has been administered to fulfil their wishes. They have been reluctant to offer us a Plan B, so the least they can do is to tell us what are the timings and trigger points for declaring success on the vaccine route.
