Because the choices of one greatly impact everyone else. Hep A can pass when dealing with less sanitary condition combined with food, which sounds like every campout cooking situation. Measles can spread very quickly with even casual contact, and is pretty bad.
"The first leg of a July 2017 trip from Andrews Air Force Base to West Virginia was likely for a Boy Scouts event, where Tillerson, an Eagle Scout, was being honored."

It is the right of the citizen to decide whether to vaccinate their children or not.
In Scouting, this is going to be the decision of the camp owners (presumably the council) so most of us are not involved in these decisions anyway. Also, I'm sure there are laws related to how these issues should and should not be handled.
When we want to encourage participation in Scouting, it is not a great idea to take on a controversial issue such as vaxing or not vaxing. Why open the can of worms? Parents can and should decide their preferences. Why make it even harder for people to enjoy camp, when there have been no instances of issues at Scout camps? (that I know of, have there been?) Why operate on fear?
Are there nurses at camp? I am sure there are health officers, but the ABC forms are what we use.
Sorry about the misquote, I tried to find the original but was struggling. I don't think it's bad to seek out a hardworking spouse, but I think it's wrong to assume that the woman will be the cook, or that one spouse should pull more of the weight so the other can go play in the woods. There is a ton of sexism out there and it is something we need to be careful to avoid as Scouters.
I also think it's wrong to push our ideologies on Scouts. The Scout Oath and Law are the most important lessons. Live those, associate with people with similar values and that's not a bad way to live your life.
If you fail to see how mistreatment of women in other countries is a more barbaric example of some of the viewpoints of some old fashioned men in the US, well, then you're missing the connection. There are different flavors and presentations of sexism. Are we going to pretend there is no verbal abuse and domestic violence towards women the US? There is a lot of it. Some of the attitudes about what women are responsible for and should be doing play into that violence.
The religious exemptions may be involved in the outbreaks in Rockland County and Brooklyn, as they are primarily impacting the orthodox Jewish communities there; non-immunized people recently returned from Israel, where an outbreak is occurring. Apart from this, anti-vax people are increasingly using the religious exemptions for their children.
