News for Parents: Delay the Jabs, Reduce the Risks

Recent research suggests that delaying vaccines for your baby can reduce the risk of asthma and other allergy development. A study of 11,531 children born in 1995 in Manitoba, Canada, where the first vaccine was normally given to children at 2 months of age, showed the following findings:

The risk of a child developing asthma was reduced by 50% if the first Diphtheria + Pertussis + Tetanus (DPT) vaccine was delayed until 5 months of age.

The risk of developing asthma was reduced by 60% if all three doses of the DPT vaccine were delayed by at least 2 months.

Asthma prevalence rates decreased from 13.8% to 5.9% with 2 or more months of delay in giving the DPT (McDonald 2008).

Another study indicated that delaying DPT and polio shots reduces the development of allergic rhinitis (e.g., hay fever) by 40%. Children who were given the DPT later, i.e., completing the primary course of DPT and polio vaccines after 12 months of age, had a significant 40% reduction in the risk of developing hay fever/allergic rhinitis compared to children who received their primary course of vaccines on time (i.e., by 6 months of age) (Bremner 2005).

However, the benefits of delaying vaccinations have to be balanced against leaving a child unprotected during the delay. In Hong Kong, would delaying the DPT and polio vaccinations be risky? In 2010, only five cases of whooping cough (pertussis) were reported, and no diphtheria, tetanus, or polio cases were reported (Hong Kong Centre for Health Protection). These numbers suggests that these conditions have been practically eradicated in Hong Kong.

IMI Homeopath Graeme Bradshaw believes parents may safely delay these vaccines until after 6 months of age, and complete them by 12 months. This benefits the child by most likely reducing the incidence of asthma development up to 60% and of allergic rhinitis, dust allergy, or hay fever by 40%.

Vaccinations are unnecessary if the child's immunity is sustained at high levels.

The top three or four recommended supplements to support your child's immunity and lessen the potential risks of vaccinations (and antibiotics).
