This is an old post, but thought I would give input anyway, just in case you are still checking. I would get Dr Sears book. I would split them up. I would do a lot of research about vaccines rather than just doing them blindly like I did....see my daughter's blog, at juliagrimesjourney.blogspot.com. She had a severe reaction to her MMR-V vaccine at one year of age and is now permanently brain damaged. A rare, but documented side effect of the vaccine is encephalitis 5-15 days post vaccination. Just do your research....
