How do you identify those immuno-suppressed 8 weeks olds?
I can answer that one.
You start with the premis that the child is not immuno-suppressed as the vast majority are not.
You take into consideration the family history and any potential sibling histories that are given more than once from the first antenatal appointment.
You take into consideration the birth circumstances and early care which will have been documented and considered by every HCP who has come into contact with that baby.
If there is any triggering issue identified during the eleven month period of pretty continuous HCP involvement from the child's conception until the time it's due it's first vaccinations, appropriateness of vaccinations will be discussed. Otherwise the question will be asked by the HV, 'Are you planning on having your child vaccinated?' (That is exactly how it was phrased with both my children - it was still introduced as a point for discussion so that the parent could discuss their options).
Even then, when you turn up for the vaccination appointment, the administering nurse asks again about any allergies or recent illnesses your baby has had. You are also given a thorough list of potential side-effects and, if you really want to know the incidence of these side effects, the nurse has it on a piece of paper in front of her.
Short of doing a blood test on every baby, I don't know how much more can possibly be done to identify the babies who could potentially have a bad reaction to the vaccines.
A pretty thorough process which you would be familiar with. If you had your children vaccinated.
