Two-Dose Protection 0 & 6 Months Provides long-term, often lifelong, immunity against Hepatitis A.
👥 Who Should Get HAVshield
Hepatitis A vaccination is recommended for several groups, especially in regions with variable food and water hygiene:
👶
Children from 1 Year of Age
Hepatitis A vaccination is part of many private/IAP-recommended schedules for children starting at 12 months, given as 2 doses 6 months apart.
🧒
Adolescents Without Prior Vaccination
Catch-up dosing is recommended for teenagers who missed childhood Hepatitis A vaccination, especially in areas with lower sanitation standards.
🧑
Adults at Occupational or Lifestyle Risk
Food handlers, healthcare and sanitation workers, and those in hostels/shared housing benefit from vaccination. Adults typically need the adult 1 mL formulation — consult your physician.
✈️
International & Domestic Travellers
Recommended for travel to regions with poor sanitation or active Hepatitis A outbreaks, ideally 2–4 weeks before departure.
🍽️
Food & Hospitality Industry Workers
Chefs, caterers and hospitality staff have higher exposure risk to faecal-oral transmitted infections like Hepatitis A.
🏥
Household Contacts of Hepatitis A Patients
Vaccination is recommended for close contacts to help prevent secondary spread of infection within families.

⚙️ How Does HAVshield Work?
1
Inactivated Antigen Injected
0.5 mL of HAVshield, containing chemically killed (inactivated) TZ84-strain hepatitis A virus antigen adsorbed onto an aluminium hydroxide adjuvant, is injected into the muscle. Because the virus is inactivated, it cannot replicate or cause Hepatitis A infection.
2
Immune System Recognition
The adjuvant helps immune cells recognise the viral antigen and mount a protective response, producing antibodies against hepatitis A virus surface proteins.
3
Antibody & Memory Cell Formation
Over several weeks the body builds protective antibody levels and immune memory cells — this is why a second dose 6 months later is needed for durable, long-term immunity.
4
Long-Term Protection
Studies indicate that a completed 2-dose Hepatitis A vaccination schedule provides protection lasting 20+ years, and possibly lifelong, against Hepatitis A infection.
✅ Because HAVshield is an inactivated (killed) vaccine, it cannot cause Hepatitis A infection — unlike live vaccines, it is generally considered suitable for a wider range of individuals, including many with weakened immunity, subject to physician advice.
⚠️ HAVshield Side Effects
HAVshield has a well-established safety profile. Most reactions are mild and self-limiting.
Common (Injection Site)
Pain, redness, swelling or induration at the injection site; mild fever; headache; loss of appetite in young children.
Difficulty breathing, facial/throat swelling, rapidly spreading hives, high fever above 104°F/40°C, or unusual drowsiness — contact your VacciHub nurse or a doctor immediately.
ℹ️ Most side effects resolve within 1–2 days. A cold compress can ease injection-site soreness; paracetamol may be used for fever/pain as advised by your physician.

🚫 Precautions and Contraindications

Currently experiencing moderate to severe acute illness or high fever — defer until recovered
Known hypersensitivity to any excipient in the formulation
Below the minimum age recommended for this paediatric presentation — consult your physician for infants
⚠️ HAVshield is an inactivated vaccine and contains no live virus, so it can generally be co-administered with other inactivated or live vaccines at different injection sites — but always confirm current spacing guidance with your physician or VacciHub nurse.
