Determined to make an impact to stem the devastating epidemic of what had become the number one killer of the era, Dr. St. John set about to be, and still remains, a strong advocate for the elimination of HIV in children on the island. This included her being the initiator of the very successful mother-to child HIV/AIDS transmission prevention programme in Barbados and served as consultant for the Paediatric HIV/AIDS surveillance programme in Barbados since 1985, with Barbados achieving a mother to child transmission at 0% in the past 7 years.
