Chicago Health Officials Urge Timely Hepatitis B Vaccination for Newborns, Citing Lifelong Risks of Infection
CHICAGO, IL – Chicago Department of Public Health officials are reinforcing the critical importance of hepatitis B vaccination for newborns, emphasizing the substantially higher risk of chronic illness in young children infected with the virus. with decades of data demonstrating safety and effectiveness, the vaccine is routinely administered within the first 24 hours of life to provide crucial early protection.
Hepatitis B is a viral infection that attacks the liver and can cause both acute and chronic disease. While often asymptomatic in adults, infection in infancy carries a far graver prognosis. “Young children who become infected are at a much higher risk of becoming chronically ill compared to adults,” explains Megan Gretsch, senior epidemiologist with the Vaccine Preventable Diseases Program at the Chicago Department of Public Health. ”up to 90% of infants with hepatitis B go on to develop chronic, lifelong infection, and 25% die prematurely of liver cirrhosis or liver cancer.”
The hepatitis B vaccine schedule begins so early in life for several key reasons, according to healthcare professionals. Physicians Pinsky and grant highlight that early administration: prevents transmission from mother to child during birth (perinatal transmission); acts as a safeguard when a parent’s hepatitis B status is unknown; protects against potential spread from infected household members or caregivers; and increases the likelihood of completing the full three-dose vaccine series.
“An infant infected at birth is infected for life,” stresses Dr.Chatterjee. “Waiting even a month or two from birth allows the virus to take hold.”
Despite concerns some parents may have, experts consistently maintain that the benefits of vaccination far outweigh the minimal risks.”Most side effects are mild, such as pain at the injection site,” say Pinsky and Grant. Severe adverse reactions are exceedingly rare, and no deaths have ever been linked to the hepatitis B vaccine itself.Dr. Chatterjee adds reassurance,noting the vaccine’s extensive study in newborns to ensure safety,even regarding potential fever or other reactions.
As its introduction in the early 1980s, over 1 billion doses of the hepatitis B vaccine have been administered globally.Ongoing monitoring,along with rigorous pre-approval testing,continues to confirm the vaccine’s safety and efficacy.
Parents with questions about the hepatitis B vaccine are encouraged to consult with their child’s pediatrician or another trusted healthcare professional, avoiding information from unreliable social media or politically motivated sources.
