About Hepatitis B Vaccine
Safe and effective vaccines against hepatitis B are available to prevent the illness and its consequences. The dosage and time required to achieve full protection will vary depending on the type of the vaccine. Immunity after vaccination lasts for at least 20 years.
Because hepatitis B virus exposure may occur through contact with blood, other body fluids and unprotected sex, vaccination is generally recommended for persons travelling to countries with intermediate to high levels of hepatitis B in the population.
Hepatitis B vaccine is often provided in combination with hepatitis A vaccine.
If you are unsure about your or your child’s level of protection against hepatitis B, see your health care provider for your personal vaccination records.
It is generally advisable to consult your health care provider at least 4 to 5 weeks before you depart.
Schedule
Hepatitis B vaccine is administered in three doses. The second dose is given 4 weeks after the first dose, and the third dose is given 5 months after the second dose. Immunity develops approximately 1 to 2 months after completion of the vaccine series.
Side Effects
Hepatitis B is a very safe vaccine. Some mild soreness may occur at the injection site and possibly a very mild fever.
