The best way to prevent hepatitis A is through vaccination with the hepatitis A vaccine. Vaccination is recommended for all children age 12 months or older, for travelers to certain countries, and for people at high risk for infection with the virus. The hepatitis A vaccine is given as two shots, six months apart. The hepatitis A vaccine also comes in a combination form, containing both hepatitis A and B vaccine, that can be given to persons 18 years or older. This form is given as three shots, over a period of six months or as three shots over one month and a booster shot at 12 months.
The recommended schedule for the hepatitis B vaccine is to receive the first shot, followed in one month by the second shot. Six months following the first shot, you should receive your third and final shot of the series.
