Have a look at the Discussion
section from one of the article's own
sources. The authors do not sound too convinced about the association between vaccinations and allergies.http://www.ncbi.nlm.nih.gov/pmc/articles/PMC1448377/Vaccination and Allergic Disease: A Birth Cohort Study

In summary, although our results in an observational cohort study demonstrated a positive association between vaccination and allergic disease, this association can be explained by ascertainment bias. These data, together with other published evidence, suggest that current vaccination practices do not have an adverse effect on the incidence of allergic disease.
What surprised me was that they could find so many un-vaccinated people as a control group in this day and age.
If there does
turn out to be a link, then it will be interesting to see how many people will be willing to pay a minor chronic insurance penalty against possible death.
