If we had infinite time and resources and pecpuld pause disease for the duration of the trial, then I'd agree with you.

Without that we delay treatment, increase costs, and slow research. And people die while we wait.

Test what's most likely to be a problem, and avoid wasting resources proving what we already know.

This is for new vaccines: we're not halting administration of existing vaccines. And the time taken for testing new vaccines seems reasonable for safety purposes, as it would be for any other medicine.

"New vaccines" in this case includes, as an example, influenza vaccines that use the same mechanism that has already been proven safe and effective and which need to be developed and deployed in the (short) time between determining the most likely influenza strains for the year and the beginning of flu season.

If annual influenza vaccines cannot be approved in time for flu season and flu deaths increase significantly over the years to come, would you consider that justifiable?
