Ah, thanks for clearing that up for me. Yes, I made a mistake in my last comment. The control group was given an established vaccine for rabies so they wouldn't know they were in the control group. An even better approach than what I originally thought.

It sounds like you generally don't trust the safety of vaccines. Is that true? Are there any vaccines other than rabies you would consider safe for use as a comparator?

Thanks for structuring your argument with a thesis, supporting evidence, and a conclusion. Even though I don't agree with your conclusion, you have my upvote because you framed your comment in a way that moves the debate forward.
