1. Name of the medicinal product

TYPHIM Vi Solution for Injection

Typhoid Polysaccharide Vaccine

2. Qualitative and quantitative composition

Each dose of 0.5 ml contains:

Purified Vi capsular polysaccharide of Salmonella typhi (Ty2 strain) - 25 micrograms

For a full list of excipients, see section 6.1.

3. Pharmaceutical form

Solution for injection

TYPHIM Vi is a clear, colourless solution.

4. Clinical particulars
4.1 Therapeutic indications

TYPHIM Vi is indicated for active immunisation against typhoid fever caused by Salmonella enterica serovar typhi, S.typhi in adults and children 2 years of age or older.

4.2 Posology and method of administration

Adults and Children over 2 years of age: A single dose of 0.5 millilitre.

The preferred route of administration for this vaccine is intramuscular although it may be given subcutaneously.

Do not administer by intravascular injection. Ensure that the vaccine does not penetrate a blood vessel.

Vaccination should occur at least 2 weeks prior to potential exposure to infection with Salmonella typhi (see section 5.1)

Children under 2 years of age: As with other polysaccharide vaccines, the antibody response may be inadequate in children under 2 years of age.

Elderly: As for adults and children over 2 years of age.

Revaccination: A single dose at 3 yearly intervals in subjects who remain at risk from typhoid fever.

4.3 Contraindications

Hypersensitivity to the active substance, to any of the excipients listed in section 6.1 or to any residual substances that may be present as traces such as formaldehyde or casein.

Vaccination must be postponed in case of febrile or acute disease.

4.4 Special warnings and precautions for use

This vaccine provides protection against the risk of infection related to Salmonella typhi but gives no protection against Salmonella paratyphi A or B or against non-typhoidal Salmonellae.

Prior to administration of TYPHIM Vi, the recipient or their guardian must be asked about the recipient's personal history, current health status and any adverse event after previous immunisations. In subjects who have a history of serious or severe reaction within 48 hours of a previous injection with a vaccine containing similar components, the need for the vaccination must be carefully considered, following a risk-benefit assessment.

As with all vaccines, facilities for the management of anaphylaxis should always be available during vaccination. As a precautionary measure, epinephrine injection (1:1000) must be immediately available in case of unexpected anaphylactic or serious allergic reactions.

Syncope (fainting) can occur following, or even before, any vaccination especially in adolescents as a psychogenic response to the needle injection. This can be accompanied by several neurological signs such as transient visual disturbance, paraesthesia and tonic-clonic limb movements during recovery. It is important that procedures are in place to avoid injury from faints.

As with all injectable vaccines, TYPHIM Vi must be administered with caution to subjects with thrombocytopenia or a bleeding disorder since bleeding may occur following intramuscular administration to these subjects.

As with any vaccine, vaccination with TYPHIM Vi may not result in protection in all vaccine recipients.

The immunogenicity of TYPHIM Vi may be reduced by immunosuppressive treatment or immunodeficiency. In such cases it is recommended to postpone vaccination until the end of the disease or treatment. Nevertheless, vaccination of subjects with chronic immunodeficiency such as HIV infection is recommended even if the antibody response might be limited.

TYPHIM Vi contains less than 1 mmol sodium (23 mg) per dose, that is to say essentially 'sodium-free'.


In order to improve the traceability of biological medicinal products, the name and the batch number of the administered product should be clearly recorded.

4.5 Interaction with other medicinal products and other forms of interaction

Separate injection sites must be used in case of concomitant vaccine administration.

TYPHIM Vi may be administered during the same vaccination session with other common vaccines (yellow fever, diphtheria, tetanus, poliomyelitis, rabies prepared on Vero cells, meningitis A+C, hepatitis A and hepatitis B).

4.6 Pregnancy and lactation


Animal reproduction studies have not been conducted with TYPHIM Vi.

Data on the use of this vaccine in pregnant women are limited. Therefore the administration of the vaccine during pregnancy is not recommended. TYPHIM Vi should be given to pregnant women only if clearly needed and following an assessment of the risks and benefits


It is not known whether this vaccine is excreted in human milk. Caution must be exercised when TYPHIM Vi is administered to a nursing mother.

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. Tiredness has been observed as a very rare reaction following administration of this vaccine (see section 4.8).

4.8 Undesirable effects

a. Summary of the safety profile

During clinical development, more than 15,000 people received TYPHIM Vi (first or second injection).

The most common adverse reactions, in all age groups, were injection site pain. In adults from 18 years of age, myalgia and fatigue were the most frequently reported systemic reactions. In children and adolescents (from 2 to 17 years of age), myalgia and headache were the most frequently reported systemic reactions.

Most adverse reactions appeared within 3 days after vaccination. Most reactions resolved spontaneously within 1 to 3 days after onset.

b. Tabulated list of adverse reactions

The adverse reactions come from clinical studies (pooled analysis) and worldwide post-marketing experience. The pooled analysis has been performed on 6 recent studies sharing the same safety standard integrating data from 1532 subjects (97 children and adolescents from 2 to 17 years of age and 1435 adults).

In each System Organ Class, the adverse reactions are ranked under headings of frequency, the most common reactions coming first, using the following convention:

Very common (≥ 1/10)

Common (≥ 1/100 to <1/10)

Uncommon (≥ 1/1000 to <1/100)

Rare (≥ 1/10 000 to <1/1000)

Very rare (<1/10 000) including isolated cases

Not known (cannot be estimated from the available data).

The table below summarizes the frequencies of the adverse reactions that were recorded after any dose of TYPHIM Vi in children and adolescents from 2 to 17 years of age and adults.

5. Pharmacological properties
5.1 Pharmacodynamic properties

Pharmacotherapeutic group: Typhoid vaccines, ATC code: J07AP03

This vaccine contains purified Vi capsular polysaccharide of Salmonella typhi (Ty 2 strain). Immunity appears within 1-3 weeks after injection and lasts around 3 years.

A double-blind, randomized, controlled efficacy clinical trial was conducted in a highly endemic area in Nepal, in both paediatric and adult populations. A total of 3,457 subjects received TYPHIM Vi. The level of protection conferred by a single dose of the vaccine was 74% against blood culture-confirmed cases of typhoid fever throughout the 20 months of active surveillance when compared with the control group.

Seroconversion rate (defined as 4-fold rise of anti-Vi antibody levels) was collected in 19 clinical trials. These trials were conducted in endemic and non-endemic areas in both paediatric and adult populations representing a total of 2,137 evaluable subjects. In adult population, seroconversion rate ranged from 62.5% to 100% four weeks after a single injection, with similar magnitude of anti-Vi immune response in non-endemic areas compared to endemic areas.

Anti-Vi antibody persistence depends on endemicity, with a trend for better persistence in endemic areas (documented up to 10 years in 83 children at levels equal or above serological correlate of protection of 1 µ g/mL). In non-endemic areas, anti-Vi antibodies persist for 2 to 3 years. Revaccination should be carried out with an interval of not more than 3 years in subjects who remain at risk of exposure to typhoid fever.

Paediatric population

In a double-blind, randomized, controlled efficacy clinical trial conducted in a highly endemic area in South Africa, a total of 5,692 paediatric subjects from 5 to 15 years of age received TYPHIM Vi. The level of protection conferred by a single dose of the vaccine was 55% against blood culture- confirmed cases of typhoid fever during the 3-year follow-up period when compared with the control group.

Immunogenicity was assessed in both endemic and non-endemic areas in paediatric population aged from 2 to 17 years. In 9 clinical trials representing a total of 733 evaluable children four weeks after a single injection of TYPHIM Vi, seroconversion rate ranged from 67% to 100%, demonstrating similar magnitude of anti-Vi immune response to what was documented with adult participants.
