Consumer medicine information (CMI) leaflet

Please read this leaflet carefully before you start using Havrix 1440 and Havrix Junior.


This leaflet answers some of the common questions about HAVRIX vaccine. It does not contain all the available information. It does not take the place of talking to your doctor, nurse or pharmacist.

All medicines and vaccines have risks and benefits. Your doctor has weighed the possible risks of you or your child having HAVRIX against the expected benefits.

If you have any concerns about HAVRIX talk to your doctor, nurse or pharmacist.

Keep this leaflet with this vaccine. You may need to read it again.


HAVRIX is a vaccine used to prevent hepatitis A infection. The vaccine works by causing the body to produce its own protection (antibodies) against this disease.

Hepatitis A is an infectious disease, which can affect the liver. This disease is caused by the hepatitis A virus.

The hepatitis A virus can be passed from person to person in food and drink, or by swimming in water contaminated by sewage. Symptoms of hepatitis A begin 3 to 6 weeks after coming into contact with the virus. These consist of nausea (feeling sick), fever and aches and pains. After a few days the whites of eyes and skin may become yellowish (jaundice). The severity and type of symptoms can vary. Young children may not develop jaundice. Most people recover completely but the illness is usually severe enough to keep people off work for about a month.

Hepatitis A is very common in many parts of the world, and the risk of infection is greatest in those areas where hygiene and sanitation are poor. Such areas include Asia, India, Africa, Central and South America, the Pacific Islands, the Middle East, and the Mediterranean basin. HAVRIX is recommended for all travellers to these areas, including people in the armed forces.

Hepatitis A occurs in Australia, but is not common. Some groups of people however, are at risk of exposure to the disease and should be vaccinated. Vaccination is recommended for:

  • healthcare workers
  • day-care centre staff
  • staff and residents of homes for the intellectually disabled
  • sewage workers
  • food handlers
  • abusers of injectable drugs
  • homosexual men
  • people in contact with an infected person
  • and people with some types of liver or blood disorders.

There is no specific treatment for hepatitis A. Therefore vaccination is the best way to protect against infection in the longer term.

HAVRIX will not protect against hepatitis caused by other agents or viruses (such as hepatitis B, hepatitis C or hepatitis E). If a person is already infected with the hepatitis A virus at the time of vaccination, HAVRIX may not prevent the disease in these people.



  • you have/your child has had an allergic reaction to HAVRIX, or any ingredient contained in this vaccine. The ingredients are listed at the end of this leaflet. Signs of an allergic reaction may include itchy skin rash, shortness of breath and swelling of the face or tongue.
    If you have/your child has had HAVRIX before and became unwell, tell your doctor or nurse before the first dose is given.
  • you have/your child has a severe infection with a high temperature. A minor infection such as a cold should not be a problem, but talk to your doctor or nurse about this before being vaccinated.
  • the expiry date printed on the pack has passed
  • the packaging is torn or shows signs of tampering

If you are not sure whether HAVRIX should be given, talk to your doctor or nurse. Do not give this vaccine to anyone else; your doctor has prescribed it specifically for you/or your child.


  • you are or think you may be pregnant or if you intend to become pregnant. Your doctor will discuss with you the possible risks and benefits of having HAVRIX during pregnancy.
  • you are breast feeding. It is not known if HAVRIX passes into breast milk, however the vaccine is not expected to cause problems in breast-fed babies.
  • you have/your child has any medical conditions, such as:
    - a bleeding disorder. Sometimes HAVRIX may need to be given differently in people with bleeding problems.
    - or an immune deficiency condition (eg. are HIV positive)
  • you have/your child has allergies to any other medicines or substances, such as dyes, foods or preservatives.
  • you have/your child has received another vaccine. HAVRIX can be given at the same time as other vaccines including: hepatitis B, typhoid, yellow fever, cholera (injectable) and tetanus. It can also be given at the same time as human immunoglobulin. HAVRIX will always be given separately from other injections.
  • you are /your child is taking any prescription or OTC (over-the-counter) medicines. In particular mention medicines that suppress the immune system, such as steroids or cyclosporin.

Some vaccines may be affected by other vaccines or medicines. Your doctor, nurse or pharmacist will be able to tell you what to do if HAVRIX is to be given with another vaccine or medicine.

Fainting can occur following, or even before, any needle injection, therefore tell the doctor or nurse if you/your child fainted with a previous injection.


HAVRIX Junior is recommended for use in children 2 to 15 years of age. HAVRIX is not recommended in children under 2 years of age, as information on use is limited.


Information on use of HAVRIX in the elderly is limited.


The doctor or nurse will give HAVRIX as an injection. If you have any concerns about how this vaccine is to be given, talk to your doctor, nurse or pharmacist.


For adults and children aged 16 years and over: the HAVRIX 1440 dose is 1mL.

For adolescents and children aged 2 to 15 years: the HAVRIX Junior dose is 0.5mL


HAVRIX will be injected into the upper arm muscle in adults and older children, and into the thigh muscle in infants. For some people with bleeding problems, the dose may need to be given under the skin (subcutaneously).

The vaccine should never be given intravenously.


HAVRIX is generally given as a single dose on an elected date.

If travelling overseas, HAVRIX should be given at least 2 weeks before departure. This is so the body has time to respond to the vaccine. If there is a risk of hepatitis A infection occurring before immunity develops, human immunoglobulin may need to be given at the same time as HAVRIX.

After one dose of HAVRIX, protection from hepatitis A lasts for at least 1 year. A second boostering dose, given 6 to 12 months after the first dose, gives longer term protection. It is predicted that protection could last for 20 years. Your doctor will advise on the need for booster dosing.


If a scheduled dose is missed, talk to your doctor or nurse and arrange another visit as soon as possible.



Keep your visits with the doctor or clinic. It is important HAVRIX doses are given at the correct times. This will ensure the best effect of the vaccine in protecting you (or your child) against hepatitis A.


Be careful driving or operating machinery until you know how HAVRIX affects you. HAVRIX should not normally interfere with your ability to drive a car or operate machinery. But in some people vaccination can cause dizziness or lightheadedness. Make sure you know how you react to HAVRIX before you drive a car or operate machinery, or do anything that could be dangerous if you are dizzy or lightheaded.


Tell your doctor, nurse or pharmacist as soon as possible if you (or your child) do not feel well during or after having had a dose of HAVRIX.

HAVRIX helps protect most people from hepatitis A, but it may have unwanted side effects in a few people. All medicines and vaccines can have side effects. Sometimes they are serious; most of the time they are not. Some side effects may need medical treatment.

Ask your doctor, nurse or pharmacist to answer any questions you may have.

Most unwanted effects with HAVRIX are mild and usually clear up within a few days. These effects, as with other vaccines, generally occur around the injection site.


Tell your doctor if you notice any of the following that are troublesome or ongoing after vaccination:

  • redness, swelling, a hard lump, soreness, bruising or itching around the injection site
  • feeling generally unwell, fever, or headache
  • loss of appetite, or feeling sick
  • tiredness, diarrhoea, vomiting, abdominal pain
  • influenza like illness, chills
  • runny or blocked nose
  • stiff joints, aching muscles
  • irritability, drowsiness, dizziness
  • pins and needles, numbness of the skin, rash


As with all vaccines given by injection there is a very small risk of serious allergic reaction. Contact your doctor immediately or go to the casualty department of your nearest hospital if any of the following happens:

  • swelling of limbs, face, eyes, inside of nose, mouth or throat
  • shortness of breath, breathing or swallowing difficulties
  • hives, itching (especially of the hands or feet), reddening of skin (especially around the ears), or severe skin reactions
  • unusual tiredness or weakness that is sudden and severe
  • convulsions

Allergy to HAVRIX is rare. Any such severe reactions will usually occur within the first few hours of vaccination.

Other events that have been reported with HAVRIX include:

  • pain in the joints or muscles, convulsions

Other side effects not listed above, can also occur during or soon after a dose of HAVRIX. Check with your doctor or nurse if you notice any other effects.

Do not be alarmed by this list of possible side effects. You may not experience any of them.


HAVRIX is usually stored at the doctor’s clinic or surgery, or at the pharmacy. But if you need to store HAVRIX always:

  • Keep HAVRIX in the refrigerator stored between +2°C and +8°C. THE PACK SHOULD NEVER BE FROZEN. FREEZING DESTROYS THE VACCINE.
  • Keep the vaccine out of the reach of children.
  • Keep HAVRIX in the original pack until it is time for it to be given.

Ask your pharmacist what to do with any left over HAVRIX that has expired or has not been used.



HAVRIX comes in glass prefilled syringes. It is a white, slightly milky liquid.


The active ingredient of HAVRIX is the killed hepatitis A virus. Two different vaccine strengths are available:

  • HAVRIX 1440: 1440 ELISA units of killed hepatitis A virus in 1mL of liquid
  • HAVRIX Junior: 720 ELISA units of killed hepatitis A virus in 0.5mL of liquid

Inactive ingredients in the vaccine are: aluminium hydroxide hydrate, polysorbate 20, amino acids for injection, phosphate salts, sodium chloride, and water. Very small amounts of neomycin sulfate and formaldehyde may also be present.

The vaccine is not infectious, and will not give you hepatitis A.

HAVRIX does not contain human blood or blood products, or any other substances of human origin.

The manufacture of this product includes exposure to bovine derived materials. No evidence exists that any case of vCJD (considered to be the human form of bovine spongiform encephalopathy) has resulted from the administration of any vaccine product.


HAVRIX is only available if prescribed by a doctor.

Active ingredient

Hepatitis A child/adolescent vaccine




1 Name of Medicine

Inactivated hepatitis A virus vaccine.

2 Qualitative and Quantitative Composition

Havrix, hepatitis A vaccine, is a sterile suspension containing formaldehyde - inactivated hepatitis A virus (HM 175 hepatitis A virus strain) adsorbed onto aluminium hydroxide hydrate.
The virus is propagated in MRC5 human diploid cells. Before viral extraction, the cells are extensively washed to remove culture medium constituents. A virus suspension is then obtained by lysis of the cells followed by purification using ultrafiltration techniques and gel chromatography. The virus is then inactivated with formalin. Residual formaldehyde in the vaccine should be not more than 0.01%.
One dose (1.0 mL) of Havrix 1440 Adult contains: hepatitis A virus (inactivated)1,2 1440 ELISA units.
1Produced on human diploid (MRC-5) cells, 2adsorbed on aluminium hydroxide hydrate.
Total: 0.50 milligrams Al3+.
One dose (0.5 mL) of Havrix 720 Junior contains: hepatitis A virus (inactivated)1,2 720 ELISA units.
1Produced on human diploid (MRC-5) cells, 2adsorbed on aluminium hydroxide hydrate.
Total: 0.25 milligrams Al3+.
The manufacture of this product includes exposure to bovine derived materials. No evidence exists that any case of vCJD (considered to be the human form of bovine spongiform encephalopathy) has resulted from the administration of any vaccine product.
Havrix meets the World Health Organization requirements for biological substances.

3 Pharmaceutical Form

Suspension for injection.
Turbid liquid suspension. Upon storage, a fine white deposit with a clear colourless supernatant can be observed.

4 Clinical Particulars

4.1 Therapeutic Indications

Havrix is indicated for active immunisation against hepatitis A virus (HAV) infection in susceptible subjects at risk of exposure to HAV. Havrix Junior is indicated in subjects aged 2 to 15 years and Havrix 1440 is indicated in subjects aged 16 years and older.
In areas of low prevalence of hepatitis A, immunisation with Havrix is particularly recommended in the following subjects.
Travellers: persons travelling to areas of intermediate or high endemicity for hepatitis A. These areas include Africa, Asia, India, the Pacific Islands, the Mediterranean basin, the Middle East, Central and South America.
Armed forces: armed forces personnel who travel to higher endemicity areas or to areas where hygiene is poor, have an increased risk of HAV infection.
Persons for whom hepatitis A is an occupational hazard or for whom there is an increased risk of transmission. These include: employees in daycare centres, particularly in situations where children have not been toilet trained; teachers and other close contacts of the intellectually disabled; staff and residents of residential facilities for the intellectually disabled; health workers and teachers in remote Aboriginal and Torres Strait Islander communities; nursing staff and other healthcare workers in contact with patients in paediatric wards, infectious diseases wards, emergency rooms and intensive care units; sewerage workers; food handlers, since food hygiene procedures and food processing methods are not always adequate to protect from contamination from food handlers.
Homosexual men: increased incidence of hepatitis A infection among homosexual males suggests that the disease may be sexually transmitted in this group.
Contacts of infected persons: since virus shedding from infected persons may occur for a prolonged period, active immunisation of close contacts is recommended. The use of vaccine in outbreak control has been shown to be more effective than the use of immunoglobulin.
Specific population groups known to have a higher incidence of hepatitis A: e.g. Australian Aboriginals, recognised community-wide HAV epidemics.
Individuals with chronic liver disease and recipients of liver transplants, as hepatitis A infections is likely to be more severe in these groups. Many injecting drug users will have pre-existing liver disease from hepatitis B or hepatitis C infection.
Recipients of blood products, such as factor VIII e.g. haemophiliacs.
Havrix will not prevent hepatitis infection caused by other agents such as hepatitis B virus, hepatitis C virus, hepatitis D virus, hepatitis E or other pathogens known to infect the liver.

4.2 Dose and Method of Administration

Havrix is administered by intramuscular injection. The vaccine should never be administered intravenously.
Each dose consists of ready-to-use sterile suspension. The vaccine should be inspected visually for any foreign particulate matter and/or variation of physical aspect prior to administration. Before use of Havrix, the syringe should be well shaken to obtain a slight opaque white suspension. Discard if the contents of the syringe appear otherwise.
The pre-filled syringe is for use in a single patient only and any residue must be discarded.

Adults (16 years and older).

A single dose of Havrix 1440 (1 mL) is used for primary immunisation.
To prolong the protective effect, a single booster dose of Havrix 1440 is recommended at any time between 6 and 12 months after the primary dose. Long-term persistence of serum antibodies after vaccination with Havrix is under evaluation. Data available after five years show persistence of antibodies which is consistent with a projected 20 years persistence (based on mathematical calculations). Further measurement of antibody titres are needed to confirm these mathematical projections.

Children and adolescents (aged 2 years up to and including 15 years).

A single dose of Havrix Junior (0.5 mL) is used for primary immunisation.
To prolong the protective effect, a single booster dose of Havrix Junior is recommended at any time between 6 and 12 months after the primary dose. The exact duration of this protection subsequent to the booster dose is unknown.
Havrix should be injected intramuscularly into the deltoid region of the upper arm in adults and older children or the antero-lateral aspect of the thigh in infants. The vaccine should not be administered intramuscularly in the gluteal region or subcutaneously/ intradermally since administration by these routes may result in a less than optimal anti-HAV antibody response.

4.3 Contraindications

Havrix should not be administered to subjects with known hypersensitivity to any component of the vaccine, or to subjects having shown signs of hypersensitivity after previous Havrix administration.
As with other vaccines, the administration of Havrix should be postponed in subjects with severe febrile illness. The presence of a minor infection, however is not a contraindication.

4.4 Special Warnings and Precautions for Use

Havrix should never be administered intravenously.
As with all injectable vaccines, appropriate medical treatment and supervision should always be readily available in case of anaphylactic reactions following the administration of the vaccine.
Syncope (fainting) can occur following, or even before, any vaccination as a psychogenic response to the needle injection. It is important that procedures are in place to avoid injury from faints.
The antibody response to Havrix may be impaired in subjects whose immune system is compromised by either disease or drugs.
Havrix should be administered with caution to subjects with thrombocytopenia or a bleeding disorder since bleeding may occur following an intramuscular administration to these subjects.
It is possible that the subjects may be in the incubation period of hepatitis A infection at the time of immunisation. It is not known whether Havrix will prevent hepatitis A in such cases.

Use in the elderly.

Clinical experience with Havrix 1440 in the elderly is also limited.

Paediatric use.

See Section 4.4 Special Warnings and Precautions for Use.

Effects on laboratory tests.

No data available.

4.5 Interactions with Other Medicines and Other Forms of Interactions

No data are available concerning concomitant administration of ISG with Havrix 1440 or Havrix Junior. Clinical experience with Havrix 720 ELISA suggests that the concomitant administration of ISG with the first dose of Havrix does not influence the seroconversion rate, but may result in a relatively lower anti-HAV antibody titre than when the primary course of vaccine is given alone. Havrix and ISG should be administered at separate injection sites.
Since Havrix is an inactivated vaccine its concomitant use with other inactivated vaccines is unlikely to result in interference with immune response. Havrix can be given concomitantly with any of the following vaccines: typhoid, yellow fever, cholera (injectable), tetanus, or with monovalent and combination vaccines comprised of measles, mumps, rubella and varicella.
Clinical experience of the concomitant administration of Havrix 720 ELISA units and the recombinant hepatitis B virus vaccine (Engerix-B) suggests no interference in the respective immune responses to each of the antigens. When given concomitantly, Havrix and Engerix-B should be administered in separate syringes at separate sites.
If another vaccine needs to be administered concurrently, the vaccines must be administered using separate syringes at separate sites.
Havrix must not be mixed with other vaccines.

4.6 Fertility, Pregnancy and Lactation

Effects on fertility.

No data available.
(Category B2)
Adequate human data on use during pregnancy and adequate animal reproduction studies are not available. Although there is no convincing evidence of risk to the foetus from immunisation of pregnant women using inactivated virus vaccines, Havrix should be used during pregnancy only when clearly needed.
Adequate human data on use during lactation and adequate animal reproduction studies are not available. Havrix should therefore be used with caution in breastfeeding women.

4.7 Effects on Ability to Drive and Use Machines

The vaccine is unlikely to produce an effect on the ability to drive and use machines.

4.8 Adverse Effects (Undesirable Effects)

Clinical trials.

Solicited and unsolicited events occurring during clinical trials are listed below. The safety profile presented below is based on data from more than 5300 subjects. Events are listed within body systems and categorised by frequency according to the following definitions: very common events ≥ 10%, common events reported at a frequency of greater or equal to 1% but less than 10% patients; uncommon events reported at a frequency of less than 1% but greater or equal to 0.1% patients; rare events reported at a frequency of less than 0.1%, but greater or equal to 0.01%, very rare events reported at a frequency of less than 0.01% patients.

Local reactions at injection site.

Very common: soreness, redness.
Common: induration, swelling.

Body as a whole.

Very common: headache, fatigue.
Common: fever (> 37.5°C), malaise.
Uncommon: influenza-like illness.
Rare: chills.


Uncommon: rash.
Rare: pruritus.


Uncommon: pharyngitis, other upper respiratory tract infections, rhinitis.


Common: nausea, diarrhoea, vomiting, appetite lost.
Uncommon: abdominal pain.


Uncommon: myalgia, musculoskeletal stiffness.


Rare: lymphadenopathy.

Central nervous system.

Very common: irritability.
Common: drowsiness.
Uncommon: dizziness.
Rare: hypoaesthesia, paraesthesia.
When ISG was given concurrently with Havrix 720 ELISA units, the incidence but not severity of the adverse events were higher, this being largely due to more reports of local adverse events.

Postmarketing data.

Since marketing of the product, elevations of serum liver enzymes (usually transient) have been reported rarely. However a causal relationship with the vaccine has not been established. Neurological manifestations occurring in temporal association have been reported extremely rarely with the vaccine and include transverse myelitis, Guillain-Barre syndrome and neuralgic amyotrophy. No causal relationship has been established.
Very rarely, allergic reactions including anaphylactic reactions, and convulsions have been reported.
Anaphylaxis and mimicking serum sickness, vasculitis, angioneurotic oedema, urticaria, erythema multiforme, arthralgia have also been reported.

Reporting suspected adverse effects.

Reporting suspected adverse reactions after registration of the medicinal product is important. It allows continued monitoring of the benefit-risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions at

4.9 Overdose

Cases of overdose have been reported during post-marketing surveillance. Adverse events reported following overdosage were similar to those reported with normal vaccine administration.
For information on the management of overdose, contact the Poisons Information Centre on 13 11 26 (Australia).

5 Pharmacological Properties

5.1 Pharmacodynamic Properties

Mechanism of action.

Havrix confers immunity against hepatitis A virus (HAV) infection by inducing the production of specific anti-HAV antibodies in normal healthy individuals.
The mean titre of anti-HAV antibodies induced by Havrix is higher than that observed after passive immunisation using specific HAV immune serum globulins (ISG). Vaccine-induced anti-HAV antibodies have been shown to be qualitatively indistinguishable from those of the specific HAV ISG.
A booster dose may be administered at any time between 6 and 12 months after the primary dose, to induce a rise in antibody titres. Long-term persistence of serum antibodies has been predicted using mathematical modelling of data obtained after vaccination of adults (17-40 years age) with Havrix 1440.
Data available after 17 years allows prediction that at least 95% and 90% of subjects will remain seropositive (≥ 15 mIU/mL) 30 and 40 years after vaccination, respectively (see Table 1).

Clinical trials.

Immunogenicity in adults.

In clinical studies involving over 400 subjects, 16 to 50 years of age, specific humoral antibodies against HAV were elicited in 88% of vaccinees after 15 days and in approximately 99% of vaccinees 1 month after the administration of a single dose of Havrix 1440 ELISA units. GMTs of seroconverters ranged from 264 to 339 IU/L at day 15 and increased to a range of 335 to 637 IU/L at 1 month following vaccination. In two clinical trials in which a booster dose was given 6 months following the initial dose, 100% of vaccinees were seropositive 1 month after the booster dose, with GMTs ranging from 3318 to 5925 IU/L.

Immunogenicity in children.

In clinical studies involving subjects 2 to 19 years of age (N = 314), specific humoral antibodies against HAV were elicited in 93% of vaccinees after 15 days and in approximately 99% of vaccinees 1 month after the administration of a single dose of Havrix Junior. The GMTs 1 month after the initial dose ranged from 194 to 305 IU/L. One month following the booster dose at month 6, all subjects were seropositive with GMTs ranging from 2495 to 3644 IU/L.
In one additional study in which the booster dose was delayed until 1 year following the initial dose, 95.2% of all subjects were seropositive just prior to administration of the booster dose. One month later, all subjects were seropositive with GMTs of 2657 IU/L.

Protective efficacy.

Protective efficacy with Havrix has been demonstrated in a double-blind, randomized controlled study in school children (age 1 to 16 years) in Thailand who were at high risk of HAV infection. A total of 40,119 children were randomized to be vaccinated with either Havrix 360 ELISA units or Engerix-B at 0, 1, 12 months. 19,037 children received a primary course (0, 1 months) of Havrix and 19,120 children received a primary course (0, 1 months) of Engerix-B. 38,157 children entered surveillance at day 138 and were observed for an additional 8 months. Using the protocol-defined endpoint (≥ 2 days absence from school, ALT level > 45 IU/mL, and a positive result in the HAVAB-M test), 32 cases of clinical hepatitis A occurred in the control group; in the Havrix group, two cases were identified. These two cases were mild both in terms of biochemical and clinical indices of hepatitis A disease. Thus the calculated efficacy rate for prevention of clinical hepatitis A was 94% (95% confidence intervals 74% to 99%).
In outbreak investigations occurring in the trial, 26 clinical cases of hepatitis A (of a total of 34 occurring in the trial) occurred. No cases occurred in Havrix vaccinees.
Using additional virological and serological analyses post hoc, the efficacy of Havrix was confirmed. Up to three additional cases of very mild clinical illness may have occurred in vaccinees. Using available testing, these illnesses could neither be proven nor disproven to have been caused by HAV. By including these as cases, the calculated efficacy rate for prevention of clinical hepatitis A would be 84% (95% confidence intervals 60% to 94%).
The benefit of post-exposure vaccination has been studied in an animal model. Primates exposed to the virulent heterologous hepatitis A strain were vaccinated with either a single dose of 360 or 1440 ELISA unit vaccine 2 days after exposure. Only partial protection was observed in the animals vaccinated with the lower dose, with three of four animals developing hepatitis A. Post-exposure vaccination with 1440 ELISA units provided complete protection against disease and HAV transmission, although 2 of the four animals had evidence of infection.

Impact of mass vaccination on disease incidence.

A reduction in the incidence of hepatitis A was observed in two countries where a two-dose Havrix immunization program was implemented for children in their second year of life. The two countries had intermediate A hepatitis virus endemicity before the program:
In Israel, two retrospective database studies showed 88% and 95% reduction in hepatitis A incidence in the general population 5 and 8 years after the implementation of the vaccination program, respectively. Data from national surveillance also showed a 95% reduction in hepatitis A incidence as compared to the pre-vaccination period.
In Panama, a retrospective database study showed a 90% reduction in reported hepatitis A incidence in the vaccinated population, and 87% in the general population, 3 years after implementation of the vaccination programme. In paediatric hospitals in Panama City, confirmed acute hepatitis A cases were no longer diagnosed 4 years after implementation of the vaccination programme.
The observed reductions in hepatitis A incidence in the general population (vaccinated and non-vaccinated) in both countries demonstrate herd immunity.
