To truly prove the efficacy of a vaccine you would have to intentionally give a test subject the virus to see if the vaccine actually works.
It's not been done once by modern western medicine because it would be unethical by modern medical practices to intentionally infect a person.
- crusso 6y agoEfficacy is still tested with vaccines because there is a statistical expectation of contracting a given disease. If you give 40,000 people a random mix of placebo and vaccines and then monitor whether or not they contract the target disease, you get an indication of efficacy by comparing the vaccinated group to the placebo group.

- yreg 6y agoWhat, why would you need to do that? That's not how preventive medicine is tested. Please explain how would your proposal be any more valid than a proper controlled study where you do the treatment on portion of your participants and wait how it works out for them.
