Ds will be 13 months on Saturday. He has received an appointment for his MMR and the combined diptheria,tetanus,whooping cough, polio and hib jab for tomorrow. After much deliberation we have decided not to go ahead with the MMR and to have the single jabs instead. My question is Is it right that they have the combined dipteria, polio etc jab at this age. He received the new mercury free one at 8,12 and 16 weeks and I was told that he would receive a booster when he was free. I have also checked the NHS 0-5 book and that also says it is given at 2, 3 and 4 months and then again when they are 3. Has anyone else been invited to have one at 13 months?
