A new study has asked whether aluminum, which is part of some childhood vaccines, can cause childhood asthma. But even if this connection is detected, this component will not be removed from the vaccines.
Scientists from the Children’s Hospital of Philadelphia again wondered whether aluminum, which has been used as an additive to childhood vaccines for decades, plays any role in the development of allergic phenomena and asthma in children. A new study has identified a possible link, but experts say it has important drawbacks and is not a reason to abandon current recommendations on the composition of vaccines. In addition, the study does not claim that it is aluminum that causes breathing problems, so it is necessary to conduct further study of this issue.
But even if this link is discovered, that is, scientists will prove that aluminum-based supplements provoke asthma in some children, the life-saving benefits of vaccines will still outweigh the possible risks. Although, it cannot be excluded that scientists will begin work on redesigning vaccines. The most important thing is that the current study does not scare away some families from long-tested vaccinations.
In order to make extraordinary statements, the same extraordinary evidence is needed. The current study could not explain the effects of some important ways of exposing children to aluminum, for example, through air or food. In addition, its results include difficult-to-explain inconsistencies. For example, why in one subgroup of thousands of fully vaccinated children, greater exposure to aluminum did not seem to lead to a higher risk of asthma.
