Data from Qatar: Pfizer COVID vaccine protects against worrying coronavirus variants

2. Better news is the ease with which this technology can be adapted for a case...

...where the existing vaccine is no longer effective.

As I understand it, for as much as I've looked into it, it basically involves small changes to a computer code, followed by scale up.

The scale up part is well understood now. We can do this.

With an intelligent population, we can beat this disease, to the extent that a subpopulation insists on a displaying a lack of intelligence, Darwin will offer a correction. Infection with this disease is something like polio; it involves long term effects, meaning that even if one refuses the vaccine, survives infection, one can expect reduced life expectancy, probably from cardiac disease.

Evolution at work, both viral and mammalian.
