A Third Vaccine Success – Oxford University breakthrough on global COVID-19 vaccine

Very promising news ‚ÄĒ and now some of the key questions for 2021 …

What is the Venn between these candidate vaccines?
Hopefully it is not perfectly overlapping so a patient can take one vaccine if another vaccine proves to be ineffective.

Where is the testing regime to allow folks to explore the efficacy at the personal level?
While it is helpful to offer a characterization of the mean-field performance of a vaccine, we cannot expect folks to ‘get back to normal’ unless they have some personal assurance that the vaccine has actually worked for them.

How long does immunity last ?
This is still unknown. 6 months, 1 year, etc. Also, even if the vaccine ‘fails’ or wanes how much does it reduce the severity of COVID-19?

What about Children?
Trials for Children have yet to begin (or have only recently started). While Children appear to have had less issues with COVID-19 (perhaps because of exposure to other coronaviruses, etc.), there is still the question of how well the vaccine will perform on Children.
