Final answer:
The CDC recommends that newborns receive the first dose of the hepatitis B vaccine at birth, the second at one to two months old, and a third dose between six and eighteen months of age.
Step-by-step explanation:
The Centers for Disease Control and Prevention (CDC) recommends a schedule for the hepatitis B immunizations for a newborn. The first dose of the Hepatitis B vaccine should be given at birth, followed by a second dose typically at one to two months of age, and a third dose between six and eighteen months of age. Vaccination protects infants from Hepatitis B, a potentially serious liver disease, with the risk of becoming a chronic condition being significantly higher in infants than in adults. The vaccination series is crucial for preventing the spread and long-term complications of the disease, which is transmitted through exposure to infectious blood or body fluids.
