I’m not sure what you mean by ‘personal agenda.’ I’m legitimately trying to have a productive conversation so please don’t take anything said as a personal affront. We’re just trying to express the importance of herd immunity as it stands from expert consensus on the subject.

If you have any studies on herd immunity not being as important, I would love to read through them.

I understand why you trust your advisor. I’m lucky enough to be friends with someone who was a professor of infectious disease, has a PhD in virology and created a vaccine. They are my go to for anything on the subject matter. Again, anything you can share on the topic is greatly appreciated.

They shouldn’t have made a personal attack like that, but they’re not wrong. Herd immunity is needed. Individual vaccination, while helpful, isn’t fool proof. Especially for highly infectious diseases like measles.
