So I'm homeschooling, or filing an exemption for my child to attend public school...but what about going on a mission? The church wants missionaries to have a bunch of vaccinations too...
Again there are a couple of options.
Firstly, there are some people who truly cannot be vaccinated. If they have certain allergies (dairy or eggs for example) then they are healthy enough to serve a mission, but cannot receive vaccinations because there is dairy and/or egg in most vaccines. For these individuals, they can still serve missions, but will most likely stay in the USA for their mission. A non-allergic individual who has simply opted-out of vaccinations would have this same option--to just stay 'stateside.' Many people are entirely comfortable with this.
If you are comfortable with vaccination, and simply didn't want to inject too much into a small child, then you have the option to get the vaccines at an older age. This is the route I intend to go with my children. I think that getting a whole bunch of shots in the last 6 months before a mission is equally inappropriate to getting a whole bunch of shots at once with an infant, so I would again spread it across a few years. When each child is in their mid-teens, I will discuss with them about missions and vaccines and inquire as to how they want to proceed. If they are comfortable with being limited in where they might go, I'm ok with that. If they want to keep the foreign/third world country door open, then we would set up a schedule to get the remaining 'required' vaccinations over the high school years. (And another reminder--keep your own records of all the vaccines your kids get and when they get them!)
