Vaccines Contribute to Allergies

There is abundant evidence that vaccines contribute to the rising incidence of allergies, eczema, and asthma in children. Several studies have shown a dramatic difference in the incidence of allergic disease, including eczema and asthma, between vaccinated and unvaccinated children. One explanation for this is the effect of vaccines on the immune system.  According to this theory, the stimulation of antibody production by vaccines causes a shift in the immune system to an overactive mode of antibody reactions to foods and environmental exposures.

Delaying vaccines results in less allergic disease

A recent study looked at whether delaying vaccines could help prevent allergic disease in children. The researchers found that delaying the DTaP (Diphtheria-Tetanus-Pertussis) vaccine for only one month in infants significantly reduced the incidence of eczema (Kiraly, 2015).

This study confirmed previous studies that found similar reductions in allergies from delaying vaccines. For example, a study published in 2008 found that delaying the initial DTaP vaccine in infants by at least 2 months reduced the incidence of asthma by half at age 7 years. Delaying  all three DTaP doses resulted in even less children with asthma (McDonald, 2008).


Imagine how much suffering could be prevented if vaccines were routinely delayed for even longer. Many countries already limit and delay vaccines for babies in order to prevent the adverse effects that occur  in young infants with their delicate and undeveloped immune systems.
