It's a good starting point for an introduction. N.D. For a deeper picture, this is excellent. This books gives detailed descriptions of eight different constitutional types of children. Constitutional treatment is deeper acting than just treating colds, aches and pains, etc. Each family must make a personal choice to immunize their children or not.
Bad reactions happen, and some children seem prone to allergies and reactions.
About the only rule of thumb that I've been able to see is that children with known egg allergies should ask about what exactly is in the shot. You can get a lot of information directly from the American Epilepsy Foundation . They will send a large package of general information. I do think these folks have some very knowledgable people who are really dedicated to assisting their patients, particularly children. Their book was open minded about using or avoiding various medications, as well as diet and particularly identifying stress factors that play an important role in triggering seizures.
