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.
Three hepatitis B vaccine schedules have been shown to induce levels of seroprotection of greater than 95% in infants. One schedule uses an initial dose administered at birth, followed by doses at 1 and 6 months of age. The next schedule has doses given at 2, 4, and 6 months of age.The third schedule is for vaccine given at 6, 10, and 14 weeks of age.nce again, the vaccine schedule of doses given at 6, 10, and 14 weeks has seroconversion rates identical to schedules with longer intervals between doses. There are limited data supporting long-term protection for the schedules with shorter intervals, but existing data do support this approach.
