That's true, vaccines and chemical drugs can have detrimental effects. vaccinations are really harmful, WHO needs to investigate this subject in depth urgently.
Fortunately there are ways you can help your child if he has suffered from the vaccines. Homeopathy is very effective, and can do wonders - the thing is, you need to find a good homeopath, otherwise the results will be poor.
I'd suggest you visit http://www.vithoulkas.com to get an idea about homeopathy, there are a lot of interesting articles there, eg about how healthier children can be born, and more on vaccines and drugs.
