Delaying vaccination may reduce risk of asthma

Posted in children, vaccines by Kathy on December 19, 2008

A study was recently released (in April) that showed a much reduced risk of asthma when the first dose of the DTP vaccine was delayed by two months. Now, this was with the older DTP vaccine, not the newer DTaP vaccine. It remains to be seen whether the effect is similar with the current vaccine, but it shows that at least one vaccine has potentially serious side effects. Parents should use caution, then, and not just assume that vaccines have no risk. The study group began with infants and checked them for asthma occurrence by the age of seven. Most “adverse reactions” that are technically blamable on vaccines have a short window of opportunity for their appearance — say a few days or at most a couple of weeks. Developing asthma several years after the initial vaccination does not fit in that window. But it doesn’t mean it doesn’t happen, nor isn’t a problem.
