US Centers for Disease Control and Prevention (CDC)

The US Centers for Disease Control and Prevention (CDC) is a US federal agency responsible for public health and safety. Recently, the CDC has been the subject of controversy due to changes in its vaccine recommendations, specifically regarding the hepatitis B vaccine for newborns. An advisory panel voted to limit the universal recommendation, now advising vaccination only for newborns whose mothers test positive or have unknown status for hepatitis B. This decision reverses a long-standing policy. The move has sparked alarm among experts, who fear it could lead to increased infection rates. Furthermore, the CDC's messaging on flu shots has been criticized as mixed and confusing, occurring during a severe flu season. These changes have prompted international concern, with Hong Kong health authorities warning parents against blindly following the US's revised immunization schedules. The CDC's actions are significant because they impact public health policy and influence vaccination practices both domestically and internationally.
