I'm glad to hear that. So I guess your daughter's cough did not turn out to be asthma? But if your kids don't have any chronic health problems, they are in the minority (or at least they would be in the United States). "An estimated 43% of US children (32 million) currently have at least 1 of 20 chronic health conditions assessed, increasing to 54.1% when overweight, obesity, or being at risk for developmental delays are included" http://www.sciencedirect.com/science/article/pii/S1876285910002500 And of course the percentage is higher than 54.1%, because the study did not cover every chronic health problem that exists.
Without wanting to change the subject of the thread to this citation, the "chronic health conditions" considered in this paper are not what I would characterize as a chronic condition (e.g. environmental and food allergies; these were the most commonly listed next to obesity). I think one should be careful about reading too much into these numbers. My son might be allergic to bannanas, but has had only one cold in his 19 months. By this evaluation, he has a chronic condition that is solved by avoiding banannas (which are gross anyway). He's vaccinated, although I'm highly doubtful his propensity to vomit when he eats banannas is related to his vaccination status. My daughter is also vaccinated and has none of the chronic health conditions evaluated.
