The Maternal Vaccination Act aims to strengthen public health efforts concerning maternal vaccination awareness and equity. It amends the Public Health Service Act to explicitly include pregnant and postpartum individuals in existing campaigns addressing low vaccination rates, broadening the focus to this critical demographic. The bill expands the scope of healthcare providers involved to include obstetric care and mandates additional activities specifically designed to increase vaccination rates among pregnant and postpartum individuals, including those from racial and ethnic minority groups, and their children. Furthermore, it authorizes an increase in funding for these initiatives, allocating $17,000,000 annually for fiscal years 2027 through 2031 to support these expanded efforts.
