Childhood asthma is different from late or adult onset asthma in one major way. IF there's no family history of asthma or allergy in the family,it WILL go away by itself. Since allergy is a major cause of asthma,no pathy is CURATIVE,in the sense that meds will NOT make it vanish,when (and IF)it has to go,it will,irrespective of treatment. But YES,we can help in REDUCING the frequency and severity of the disease through vaccines and long term meds.
