Is there a collection, meta analysis or review of significant, independent studies that prove the efficacy of vaccinations? I am in discussion with a anti-vaccinationist who claims that the efficacy has not been proven. She does not trust in studies commissioned by vaccine manufacturers because she believes that they are in a conflict of interest. I have no expertise in this field, but I would like to show her that she is wrong and that the efficacy (as well as the effectiveness) of vaccinations is sufficiently proven. Can you recommend good literature?
Thanks a lot!
