Evidence from global health data, systematic reviews, and economic models consistently supports the safety, efficacy, and cost-effectiveness of hepatitis B vaccination protocols for newborns and infants.
The retrieved literature thoroughly supports the claim that hepatitis B vaccines are safe and cost-effective, particularly in the context of newborn and childhood immunization programs. Papers 1, 2, 4, 5, and 7 provide direct or supportive evidence regarding safety, efficacy, and cost-effectiveness (including modeling and review data). No papers refute the core claim.
