I find it interesting and also confusing how invested random people on the internet are about the outcome of vaccination (which could theoretically cause an issue for a small percentage of the population), as opposed to say climate-denial (which will undisputably cause a much bigger issue for the entire population)
I'm invested because I'm planning on having a kid. For the first year of my next kid's life there is no vaccine that can protect him/her from disease, except everybody else getting vaccinated.
Note well: I am not a doctor. I don't even play one on TV.
