As per the Singapore National Childhood Immunisation Schedule (NCIS), it is recommended that all children receive three doses of the Hepatitis B vaccine at appropriate intervals. The vaccination series typically begins with the first dose administered at birth, and children usually complete the series by 6 months of age. However, in certain circumstances, it may take longer than 6 months to finish the entire series.
Under the Singapore National Adult Immunisation Schedule (NAIS), adults aged 18 years or older who have not received the Hepatitis B vaccine previously, or lack evidence of past infection or immunity, are advised to undergo a three-dose regimen. This entails the administration of the first dose, followed by the second and third doses at one month and six months after the initial vaccination, respectively.
Adhering to these recommended vaccination schedules is crucial in providing comprehensive protection against Hepatitis B, both in childhood and adulthood. It contributes to individual health and well-being while also playing a key role in public health efforts to control the spread of Hepatitis B.
