U.S. Senator Bill Cassidy, M.D., posted a series of messages on September 1, 2025, addressing issues related to Hepatitis B vaccination and recognizing the contributions of Louisiana workers.
In his first post, Cassidy referenced his background as a liver doctor serving poor and underserved patients. He stated, “As a liver doctor who spent his life’s work treating poor and underserved patients, I can tell you that many patients do not get tested at birth, and it can lead to a debilitating, life-altering condition for the rest of their life. It could have been prevented by a proven safe” (September 1, 2025).
Later the same day, Cassidy responded to misinformation about the duration and purpose of the Hepatitis B vaccine. He wrote, “Completely inaccurate. I have taken care of these patients throughout my medical career. The vaccine lasts decades, not a few years. And we give it to newborns because Hepatitis B is often transmitted from mothers to babies, which gives a child a 95% chance of becoming” (September 1, 2025).
Cassidy also took time to highlight the role of Louisiana’s workforce in supporting the national economy: “From shrimpers and alligator farmers to teachers, doctors, drillers, and beyond, Louisiana workers keep our nation’s economy strong.” (September 1, 2025).
Hepatitis B is an infectious disease that can be passed from mother to child during childbirth if preventive measures are not taken. According to health authorities such as the CDC and WHO, administering the Hepatitis B vaccine shortly after birth significantly reduces this risk by providing long-term immunity against the virus.
Senator Bill Cassidy is both a physician specializing in hepatology and an elected official representing Louisiana in the U.S. Senate.
