    Attenuated virus vaccines have been tested for over 50 years.

    mRNA vaccines have been tested and trialled for over 20 years before covid. the only difference between the uses of mRNA as cancer treatment delivery and covid is the minute amount of RNA that is used by the immune system to identify the virus and to deliver appropriate antibodies.

    your arguments are deeply erroneous and uninformed.
