Hepatitis A Vaccine for Children: What Parents Should Know
The short version: the hepatitis A vaccine protects children from the most common cause of “dirty water jaundice”, and it can usually be given from the first birthday. It isn’t part of the free routine schedule in Pakistan or India at present, so parents have to ask for it; your paediatrician will tell you which brand, how many shots and when.
At a glance for parents
- What it protects against: hepatitis A, a liver infection spread through contaminated water, food and hands.
- From what age: usually from 12 months. Not given to babies under 1 in routine practice.
- Schedule: depends on the brand; the paediatrician sets it.
- Where: private clinics and hospitals; ask whether your area has any government programme.
- Still needed: boiled water, soap handwashing and safe food, because the vaccine doesn’t cover hepatitis E, typhoid or cholera.

A school sends a note home: three children in class 2 have jaundice; another parent says the hepatitis A shot is “extra, not needed”. A third says it’s essential. Confusing. Both miss something. This guide lays out the facts so you can have a clear conversation with your child’s doctor.
Hepatitis A in children, explained simply
The liver is like a big kitchen inside the body; it cleans the blood and makes bile. The hepatitis A virus gets into that kitchen and inflames it for a few weeks. It travels from one person’s stool to another person’s mouth, through water, ice, raw food or hands that weren’t washed with soap. Floods and barsaat make that far easier.
Surprise. In children under 6, hepatitis A is often so mild that parents never notice; there may be a tummy ache and some tiredness, or nothing at all. Older children and adults get sicker, with more jaundice and weeks off school or work. Rarely, the liver fails, and that risk rises with age. For the desi jaundice fixes worth skipping, see jaundice at home and the sugarcane myth.
What the vaccine does, and by age
A vaccine is a practice drill. Nothing more mysterious. The hepatitis A vaccine shows the body a harmless version of the virus, so if the real one arrives in a glass of water, the body already has its defence ready.
| Age | What parents should know |
|---|---|
| Under 6 months | Not given. Breast milk or formula only, and safe hands for anyone preparing feeds. |
| 6 to 12 months | Not usually given. |
| 1 to 3 years | The usual time to start. Ask at the 12 or 15 month visit. |
| 3 to 6 years | Catch-up is fine. |
| Over 6 years | Still worth asking; older children get sicker from hepatitis A. The doctor may suggest a blood test first in some cases. |
Two kinds are used in South Asia. One is an inactivated (killed) vaccine given as a short course of injections; another is a live, weakened vaccine that some brands give as a single shot. Both work. The paediatrician will choose based on availability and your child’s health, and will write the dates on the vaccine card.
Did you know? Once a child has had hepatitis A, they’re protected for life, which is why many adults who grew up in South Asia already have antibodies without ever knowing they were ill.
Is it in the free EPI or routine schedule?
Not at the moment. Pakistan’s EPI and India’s routine programme give free vaccines for polio, measles, hepatitis B and more, but hepatitis A is usually bought privately. Programmes change. Check locally. Our children’s vaccination schedule guide covers the free EPI teeke, and hepatitis B, which is in the schedule, is explained in hepatitis B and C in Pakistan.
Worried about cost? Say so; doctors can tell you which option is more affordable and whether a single-shot brand suits your child.
Before the appointment: a parent’s checklist
- Bring the vaccine card so the doctor can fit the new shot around the other teeke and write the next date in the right place, because a lost card is the most common reason a second dose gets missed.
- Mention illness: a child with a high fever usually waits until well. A runny nose? Normally fine.
- Mention allergies to any earlier vaccine, and any illness or long-term medicine that affects your child’s immunity, because the live, weakened type of hepatitis A vaccine is not given to children whose immune system is weakened and the doctor will pick the killed type instead.
- Ask three things. Brand, number of injections, next date.
- Afterwards: a sore arm or thigh, a mild fever or a fussy, clingy child for a day is common and usually settles on its own, so offer extra feeds or fluids, lots of cuddles and an early night.
- Fever medicine: if the doctor advises it, the amount goes by the child’s weight from the pack or the pharmacist. Don’t combine syrups that contain the same drug.
Rare but urgent after any vaccine: swelling of the face or lips, difficulty breathing, a widespread rash or collapse in the first hour, which is why clinics ask you to wait 15 to 30 minutes. See a doctor the same day for fever of 39 °C or more with the child unwell, fever lasting over 3 days, a fit, or a child who is floppy or hard to wake. For hepatitis itself, go the same day for yellow eyes, dark urine, pale stool, or vomiting everything; go now for drowsiness, confusion or bleeding. Your local emergency number is 1122 in Pakistan and 112 in India.
Why hygiene still matters after the vaccine
One vaccine, one virus. Barsaat brings several others through the same dirty water: hepatitis E, typhoid, cholera and rotavirus diarrhoea.
- Water: boil it. A full rolling boil for at least 1 minute, cooled covered.
- Hands: soap and water for 20 seconds before eating and after the toilet. Sing it.
- School lunch: send boiled water from home in a bottle your child knows is theirs, and skip gola ganda, cut fruit and the street drinks made with raw ice for as long as the flood season lasts, even when friends are buying them.
- Diarrhoea: ORS (1 litre clean water, 6 level teaspoons sugar, half a level teaspoon salt, or a pharmacy sachet) in small sips, and keep breastfeeding.
Myth: children don’t need it because hepatitis A is mild in kids
Partly true, mostly misleading. Young children often have mild illness, but they pass the virus to parents, grandparents and pregnant relatives, who can get much sicker. Older children miss school, too. The vaccine is a decision for each family with their doctor, not a luxury and not a must at any price.
Still unsure? Ask. More barsaat health guides for families are on our Barsaat and Flood Season hub.
Hepatitis A vaccine questions parents ask
At what age is the hepatitis A vaccine given?
Usually from 12 months onwards. Older children and teenagers can still have it as catch-up; your paediatrician will pick the timing around the other teeke.
How many doses of hepatitis A vaccine does a child need?
It depends on the brand. Some are a course of injections months apart and some are a single shot; the paediatrician will tell you and write the next date on the card.
Is the hepatitis A vaccine free in Pakistan?
Not yet. It isn’t part of the routine free EPI schedule at present, so it’s usually given at private clinics; ask your local health centre in case a programme runs in your area.
Is the hepatitis A vaccine safe for children?
It has a long safety record worldwide. A sore arm, mild fever or fussiness for a day is common; serious allergy is rare, which is why the clinic asks you to wait briefly after the shot.
What are the side effects of the hepatitis A vaccine?
Pain or redness where the needle went, mild fever, tiredness or a slightly upset tummy for a day or two; call the doctor for a high fever, a fit or a child who seems very unwell.
Can the hepatitis A vaccine be given with other vaccines?
Usually yes, at the same visit in a different limb; the paediatrician will plan it with the rest of the schedule.
Does a child need the vaccine if they already had jaundice?
Maybe not. If the jaundice was confirmed as hepatitis A by a blood test, the child is protected for life; if the cause was never tested, ask the doctor whether to vaccinate anyway.
Does the hepatitis A vaccine protect against hepatitis B or E?
No. Hepatitis B has its own vaccine in the EPI schedule; there’s no widely available hepatitis E vaccine in Pakistan or India, so safe water is the protection.
How long does the hepatitis A vaccine protect?
Decades, likely. A completed course is expected to protect for many years; boosters aren’t routinely needed for healthy children.
Should the family be vaccinated if one child has hepatitis A?
Ask the doctor quickly. Sometimes unvaccinated household contacts are offered the vaccine soon after exposure; soap handwashing and separate towels help in the meantime.
