About Hepatitis -A vaccine
I had got my kid vaccinated last year on 28th March 2025 for first shot of Hepatitis -A vaccine the next due date was in September 2025 but we missed. Can we get her vaccinated now for second dose or we need to restart vaccination again? If we get her vaccinated now will it develop immunity against disease?

You can take the second dose now. No need to start from the beginning. She will get very good immunity against the disease if you take the dose now also

No need to restart the vaccination course. You can give the 2nd dose of Hepatitis A vaccine now itself. Even if delayed, the booster dose will still help develop good long-term immunity.

There is no need to restart the schedule. You can take the second dose now. And it usually provides adequate immunity.

If live conjugated vaccine like biovac given,only single dose is sufficient,not to give second dose,
For inactivated hepatitis A vaccine 2 doses required,
If it is inactivated then give 2nd dose

According to the CDC and most pediatric guidelines, the second dose of the Hepatitis A vaccine is usually given 6 to 12 months after the first. However, if that window is missed, you should simply administer the second dose as soon as possible.
Next Steps
Since it is now May 2026, you are roughly 8 months past the originally scheduled September date. You should schedule an appointment with your pediatrician to receive the second dose.
Once this second shot is administered, the series is considered complete
