Great, under-appreciated point.
Current, authorized only under emergency condition, vaccines are completely new tech with no history.
Good modern vaccines are built on current knowledge. They take time.
The new technologies with vaccines will also develop over time, and may well prove a Godsend in the future.
We'll see. Novavaxx may well do the job, the old heavyweights doing the job in the end, the big boys picked up a tens of billions, and ah, whats next. 'bout due for a asteroid!
