I have two sons, neither of which have had the MMR, but both had the other standard childhood vaccinations.
My eldest son (now 9) was due his MMR when the whole autism scare kicked off. My husband has a son from a previous relationship (now 12) who is quite severely autistic, and the risk just seemed too great for our son. We thought long and hard, and at the end of the day both our instinct's were no, no, no. This obviously followed with our second son.
I could not have lived with the thought that I had deliberately taken my son to the doctors and allowed someone to inject him with a substance that could have damaged him so much. (Obviousy I do not blame anyone who did have the MMR and suffered an adverse reaction - you should expect to trust that the information provided is accurate and in your child's best interest, and to be honest I probably would have done if I had not seen autism at first hand with my stepson.)
With hindsight, I am very glad they didn't have the MMR, as my eldest son shows signs of being very mildly autistic anyway, albeit high functioning. I strongly believe that if he had his MMR we would be looking at a totally different child today.
However, I also have to face the fact that either of them could contract measles or mumps at any time and have a bad reaction. I also have to put up with people thinking they have a right to criticise my choice and tell me that I am wrong, especially it seems form within the healthcare profession itself.
Our HV at the time was obviously disapproving, and told me to go to the local hospital for children and babies who had been born to mothers who had contracted rubella whilst pregnant, and see if I still thought I had a right to not have my children vaccinated. Well yes, I do have that right, as my obligation is to my own children's health and wellbeing, and whilst I am terribly sorry that these children have been affected the way they have, it was not my choice to have a child when I have not been vaccinated against rubella and it was not me who withdrew the single rubella vaccine for pre-pubescent girls.
I also believe that the other childhood vaccinations contained mercury, which cannot be passed out through the body and therefore accumulates, and which is also highly toxic. This type of vaccination, I believe, has been banned by moth other countries, but was still widely used in th UK. That has to set alarm bells ringing, surely? I had my boys vaccinated against the other childhood illnesses despite this, as the illnesses themselves seem much more serious.
