The baby, the baby, the baby!!!!
If we can force a medical procedure to, maybe, save a life of someone down the line, certainly we can deny an elective medical procedure to definitely save the life of a child.
Or, likewise, individual medical autonomy trumps the and health of those who may be directly (the unborn child) or indirectly (the theoretical persons with pre existing conditions who may catch the disease from someone who caught the disease from someone who caught the disease from you) affected by your medical choice.
