Answer a few questions to get personalized guidance on catch-up hepatitis A vaccine timing for kids, including missed first doses, missed second doses, and uncertain vaccine records.
Missing a hepatitis A vaccine dose does not usually mean your child has to start the series over. In many cases, the next step is simply to continue with the recommended catch-up schedule. Because the right timing can depend on your child’s age, how long the dose has been delayed, and whether any previous dose was given, it helps to review the details before deciding what to do next.
If your child never got the first hepatitis A vaccine dose, the next step may be to begin the series now based on age and vaccine history.
If your child missed the second hepatitis A shot, catch-up is often possible without restarting the series, but timing still matters.
If records are unclear, guidance may depend on your child’s age, past visits, and whether you can confirm any prior hepatitis A immunization.

A missed hepatitis A vaccine dose often means your child may need a catch-up dose rather than restarting the series. The next step depends on your child’s age, whether any previous dose was given, and how long the schedule has been delayed.
If your child missed the second hepatitis A shot, they may still be able to complete the series with a catch-up dose. In many cases, restarting is not necessary, but the exact recommendation should be confirmed with a clinician.
A delayed hepatitis A vaccine schedule does not usually mean the series must be restarted. Catch-up guidance is often based on continuing from the last valid dose, but your child’s clinician should confirm the plan.
