Communicating what “vaccine effectiveness” essentially means

vaccine effectiveness

what was never communicated to the public was that these mRNA vaccines are experimental in every way that matters.  A necessary experiment under the circumstances, but an experiment nevertheless, on a very large population.  This does not mean, however, that the molecular, cellular, and technical details of the production of the vaccines are experimental.  These are standard in every molecular biology research laboratory.

Relative risk reduction is not well intuited.
