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.
1 Protection begins four to six weeks after the first shot. 2  The CDC has an information sheet about the Hepatitis A vaccine. 3  The Hepatitis B and combined Hepatitis A/B vaccines usually are given in a series of three shots, with the second shot a month after the first, and the third shot six months after the first. For example, at the Cerro Gordo County Department of Public Health in Iowa, there is no consultation fee, and a Hepatitis A vaccination costs $30 to $35 per dose for a total of $60 to $70.
