I'm not from a bio-science area but AFAIK mRNA vaccines are robust.
1. The same mechanism of deliver is used so it's already tested and know to be safe/effective.
2. It replicates the same protein(s) found on the virus. So it will not due more damage than getting the virus and it will have a high probability of being effective.
