All vaccines carry a risk. (All medications carry a risk.)
New vaccines carry a greater risk.
These vaccines have been rushed, so the risk is even greater.
These vaccines have been approved for emergency use, reinforcing the previous point.
This is a fundamentally different type of vaccine, so the risk is even greater (especially the long-term risk).
Taking all that into account, great caution should be observed in using these vaccines. The risk must be balanced against the benefit. Covid-19 IS deadly. It is like a bad flu, probably even a VERY bad flu. But it is not comparable to the 1918/1919 pandemic. It is therefore highly questionable whether it is justifiable for large numbers of people to be vaccinated, especially the young and healthy. And even more questionable whether vaccination should be compulsory.
I would suggest a slower vaccination program - voluntary, health workers, the elderly and those with comorbidities - and then closely monitor for adverse reactions, increasing the speed of vaccination if these are relatively few and minor.
Except when, as in the vast majority of cases, it's more like a slight cold.
