I feel you should be aware of the following.
Your child's eczema will have been brought on by the first vaccinations. Wat usually happens is that the child is taken to the Doctor who prescribes something that suppresses the eczema - like a steroid/cortisone cream. The eczema is suppressed so the dis-sease now goes on a deeper level - to the lungs and this is what starts the asthma/wheezing.
My suggestion to you would be to think very carefully about whether the next lot of vaccinations that you talk about are really necessary in a child who is already suffereing from the effects of them. You may wish to become more informed by reading some of the stuff on

Lycopodium may or may not be the correct remedy.We don't have the full case history so it is difficult to tell. As Dr Leela suggests - Do discuss your concerns with your homeopath. That is what we are there for. My patients know that they can always phone me with their queries.
