Oh please! Drug trials with paid volunteers happen all the time and mRNA vaccines were invented and used on people prior to Covid so the safety risks were minimal. Those people are not heroes. You might have called them heroes if they participated in a challenge trial (i.e. were deliberately infected with the virus) but that never happened.
