4. Clinical Particulars
4.1 Therapeutic Indications
ViATIM is indicated for simultaneous active immunisation against typhoid fever and hepatitis A virus infection in subjects from 16 years of age.
ViATIM should be given in accordance with official recommendations.
4.2 Posology And Method Of Administration
Posology
The recommended dosage for subjects of at least 16 years of age is 1 millilitre of the mixed vaccine.
Initial protection is achieved with one single dose of ViATIM. Protective levels of antibody may not be reached until 14 days after administration of the vaccine.
In order to provide long-term protection against infection caused by the hepatitis A virus, a second dose (booster) of an inactivated hepatitis A vaccine should be given. ViATIM may be be used to provide one or both doses of hepatitis A vaccine as follows:
• In subjects who have received one dose of ViATIM:
- either a dose of monovalent hepatitis A vaccine should be given within 36 months and preferably within 6 to 12 months (see section 5.1)
- or, if continued protection against typhoid is also required, a second dose of ViATIM may be given provided that approximately 36 months have elapsed since the first dose.
• In subjects who have received one dose of monovalent hepatitis A vaccine:
- ViATIM may be used to provide the second dose (booster) of hepatitis A vaccine if protection against typhoid fever is also desirable. It should be given within 36 months of the hepatitis A vaccine and preferably within 6 to 12 months.
It is predicted that HAV antibodies persist for many years (beyond 10 years) after the second dose (booster).
In subjects who remain at risk of typhoid fever, revaccination against typhoid fever should be carried out with a single dose of a purified Vi polysaccharide typhoid vaccine every 3 years, (see section 5.1).
Method of administration
ViATIM should be administered by slow intramuscular injection in the deltoid region.
ViATIM must not be administered intravascularly.
ViATIM should not be administered into the buttocks due to the varying amount of fatty tissue in this region, nor by the intradermal route, since these methods of administration may induce a weaker immune response. ViATIM may be administered by the subcutaneous route in patients with thrombocytopenia or in those at risk of haemorrhage.
See section 6.6 for instructions for preparation.
4.3 Contraindications
Hypersensitivity to the active substance(s) or to any of the excipients or to neomycin (present in trace amounts as a residual of the manufacturing process).
Vaccination should be delayed in subjects with an acute severe febrile illness.
4.4 Special Warnings And Precautions For Use
As with all vaccines, appropriate facilities and medication such as epinephrine (adrenaline) should be readily available for immediate use in case of anaphylaxis or hypersensitivity following injection.
Immunogenicity of ViATIM could be impaired by immunosuppressive treatment or in immunodeficient subjects. It is recommended to delay vaccination until the completion of any immunosuppressive treatment. Subjects with chronic immunodeficiency such as HIV infection may be vaccinated if the underlying immunodeficiency allows the induction of an antibody response, even if limited.
Because of the incubation period of hepatitis A disease, infection may be present but not clinically apparent at the time of vaccination. It is not known whether ViATIM will prevent hepatitis A in this case.
ViATIM does not protect against infection caused by other known liver pathogens including hepatitis B, hepatitis C and hepatitis E viruses.
ViATIM does not protect against infection by Salmonella enterica other than serotype typhi.
As with any vaccine, a protective immune response may not be elicited in all vaccinees.
4.5 Interaction With Other Medicinal Products And Other Forms Of Interaction
ViATIM must not be mixed with any other vaccine in the same syringe.
ViATIM is a combination of purified Vi polysaccharide typhoid vaccine and inactivated hepatitis A vaccine. Although concomitant administration with other inactivated vaccines using different syringes and at different injection sites has not been specifically studied, it is anticipated that no interaction will be observed.
Concomitant administration of yellow fever vaccine with ViATIM has not been specifically assessed. However, based on data obtained from the concomitant administration of the monovalent vaccines (purified Vi polysaccharide typhoid vaccine and inactivated hepatitis A vaccine) with yellow fever vaccine, no interference with the immune responses to any of these antigens would be expected.
The effect of concomitant administration of immunoglobulins on the immunogenicity of ViATIM has not been assessed. Therefore, interference with the immune response of ViATIM cannot be ruled out. Data obtained from concomitant administration of immunoglobulins with the monovalent inactivated hepatitis A vaccine showed that anti-HAV seroconversion rates were not modified whereas anti-HAV antibody titres could be lower than after vaccination with the monovalent vaccine alone.
4.6 Pregnancy And Lactation
Pregnancy
Data on a limited number (more than 150 cases with monovalent Vi polysaccharide typhoid vaccine, more than 40 cases with monovalent inactivated hepatitis A vaccine and more than 10 cases with ViATIM or the two components given simulatenously) of exposed pregnancies indicate no adverse effects of ViATIM on pregnancy or on the health of the foetus/new born child. To date no other relevant epidemiological data are available. Animal studies do not indicate direct or indirect harmful effects with respect to pregnancy, embryonal/foetal development, parturition or post-natal development (see section 5.3).
Caution should be exercised when prescribing to pregnant women.
When the patient is considered to be at risk of only one of hepatitis A or typhoid fever, the monovalent vaccine should be used.
Lactation
It is unknown whether ViATIM is excreted in human breast milk. The excretion of ViATIM in milk has not been studied in animals. A decision on whether to continue/discontinue breast-feeding or to administer or not administer ViATIM should be made taking into account the benefit of breast-feeding to the child and the benefit of ViATIM to the woman.
4.7 Effects On Ability To Drive And Use Machines
No studies on the effects on the ability to drive and use machines have been performed. Dizziness has been observed as an uncommon reaction (>1/1000, <1/100) following administration of this vaccine (see section 4.8).
4.8 Undesirable Effects
Adverse event data are derived from clinical trials and worldwide post marketing experience.
Within each system organ class the adverse events are ranked under headings of frequency, most frequent reactions first, using the following convention:
Very common (>1/10), Common (>1/100, <1/10), Uncommon (>1/1000, <1/100), Rare (>1/10000, <1/1000), Very rare (<1/10000), including isolated reports.
Within each frequency grouping, adverse reactions are ranked in order of decreasing seriousness.
Clinical Studies
The safety profile of ViATIM was evaluated in nearly 1100 subjects included in 5 clinical studies. The most commonly reported reactions were those occurring at the injection site.
The adverse reactions observed with ViATIM were as follows:
Nervous system disorders
Very common: headache.
Uncommon: dizziness.
Gastrointestinal disorders
Common: nausea, diarrhoea.
Skin and subcutaneous tissue disorders
Uncommon: pruritus, rash.
Musculoskeletal and connective tissue disorders
Very common: myalgia.
Common: arthralgia.
General disorders and administration site conditions
Very common: malaise, asthenia, injection site disorders (pain, induration, oedema, erythema).
Common: fever.
Pain at the ViATIM injection site was reported in 89.9% of subjects (severe in 4.5%). For subjects who received the two monovalent vaccines concomitantly at separate injection sites, pain was reported in 83.2% of subjects (severe in 5.0%) for both vaccine sites combined. Pain was reported by 79.3% of subjects (severe in 5.0%) at the Vi vaccine site and by 50.3% of subjects (severe in 0.6%) at the hepatitis A vaccine site.
Pain at the injection site lasting more than 3 days was reported by 17.4% of subjects after ViATIM, by 2.8% of subjects for the monovalent Vi vaccine site and by 0.6% of subjects for the monovalent hepatitis A vaccine site.
Severe oedema/induration (> 5 cm) was reported in 7.9% of subjects at the ViATIM site. For subjects who received the two monovalent vaccines concomitantly at separate injection sites, severe oedema/induration was reported in 1.7% of subjects for both vaccine sites combined (in 1.1% of subjects at the Vi vaccine site and in 0.6% of subjects at the hepatitis A vaccine site).
The overall incidence of systemic reactions was similar between subjects who were vaccinated with ViATIM and subjects who received the two monovalent vaccines concomitantly at separate injection sites.
All reactions resolved without any sequelae.
