Vaccination against Hepatitis B is highly efficient when administered at the appropriate time and intervals. The vaccination regimen consists of 2 or 3 vaccines (depending on the brand) given over a period of 6 months. Ideally the vaccine should be administered at birth. However, it is never too late for vaccination (unless an individual has acquired hepatitis B already). Vaccination of those at risk, which includes health-care workers and those living with persons with Hepatitis B should be a priority.
