Scientific Evidence Underpins Public Health Policies in Hong Kong
Recent media inquiries have raised concerns about the use of pharmaceutical products containing acetaminophen (paracetamol) by pregnant women and the need for newborns to receive hepatitis B vaccination. The Department of Health (DH) in Hong Kong has emphasized that public health policies and medical advice must be based on scientific evidence. Rigorous large-scale studies have confirmed that there is no association between paracetamol use during pregnancy and autism or attention deficit/hyperactivity disorder (ADHD).
