Hello, complete vaccination include three doses, at (0 , 1month and at 6month). Ideally, hepatitis B vaccination should begin ≥6 months before travel so the full vaccine series can be completed before departure. Because some protection is provided by 1 or 2 doses, the vaccine series should be initiated, if indicated, even if it cannot be completed before departure. Optimal protection, however, is not conferred until after the final vaccine dose is received, and travelers should be advised to complete the vaccine series. An approved accelerated vaccination schedule can be used for people traveling on short notice who face imminent exposure or for emergency responders to disaster areas. The accelerated vaccination schedule calls for vaccine doses administered at days 0, 7, and 21–30(days) ; a booster should be administered at 12 months to promote long-term immunity. So please get your first dose of hepatitis today itself.
