PP_ - It is a form of the Rhogam shot for RH- women.
DD was never vaxxed, no antibiotics. She has mild asthma(viral-induced, maybe 5 attacks per year, NOT like daily issues), which runs in dh's family, his entire sibling group, his father, and his other kids all have it, and they all outgrow it by about puberty. Not really a big deal - it looked like dd might not get it, but then she caught RSV at about 6 months, which our ped said might have damaged her lungs, thus bringing on the asthma, or it just might have been that she was asymptomatic for the first 6 months of her life and would have developed asthma anyway, without the RSV. (She didn't really have risk factors for the RSV - born at 41.5 weeks, at almost 9 pounds, NOT a preemie, lol, was BF, etc.....)
Otherwise, very healthy, never an ear infection, or any illness requiring medicine/doctor visit, etc, hit all milestones early, etc.
