Everyone makes mistakes, an hopefully the child will be okay. It is often difficult for a parent, especially an emotional mother, to stand strong when a health care professional is sing persuasive. I certainly don’t feel divorce talk is warranted whether in jest or not. In times like this parents need to support each other and focus on the welfare of the child over the next few days. Hopefully this will be an important lesson regarding health professionals, vaccines and hospitals. It is to soon to sue, but I would contact a malpractice attorney regarding documentation of dates of all prior vaccines, discussions regarding the improper dose given and physician advise, any advise from the Poison Control Center, and carefully document the child’s temperature and behavior for a full 2 weeks. Document conversations thus far: pediatrician’s RSV shot recommendations, anything the nurse or medical assistant said during administration, the phone call from the doctor. Do it while fresh in you memory. Call the doctor back with questions. Any unusual infant behavior, go immediately to the ER, preferably at a large teaching hospital, not a suburban hospital or urgent care. Teaching hospitals have the latest equipment and tend to be more up to date on new procedures.
