All children should be vaccinated and must be at least 12 months old to get the first shot. Discuss the hepatitis A vaccine with your child's doctor.
Adults at higher risk of getting hepatitis A and people with chronic liver disease should also be vaccinated.
If you are traveling to countries where hepatitis A is common, including Mexico, try to get both shots before you go. If you don't have time to get both shots before you travel, get the first shot as soon as possible. Most people gain some protection within 2 weeks after the first shot.
