My DS (15 months) is soon to start having his single vaccines...I'll be around 23 weeks pregnant when he has the measles jab and then the new baby will be around 8 weeks old when he's due to have the Mumps vaccine. The Rubella will follow 6 months later. I've been given conflicting advice about whether there's risk to my unborn baby, or the baby when it is born. Can anyone advise please?
