Vivotif® Singapore. SUMMARY OF PRODUCT CHARACTERISTICS
1. Trade Name of the Medicinal Product
2. Qualitative and Quantitative Composition
The composition in terms of active ingredients is as follows:
– Salmonella enterica serovar Typhi (abbr. S. typhi) Ty21a not less than 2 x 109
cells Quantities expressed per capsule.
3. Pharmaceutical Form
Enteric-coated capsule, for oral administration to humans.
4.1 Therapeutic Indications
For active oral immunisation against typhoid fever in children aged 6 years and over,
adults and elderly.
4.2 Posology and Method of Administration
Children aged 6 years and above, adults and elderly: One capsule is to be taken on
day 1. The second capsule should be taken on day 3 and the third capsule on day 5.
Unless the immunisation schedule of 3 vaccine capsules is completed, an optimal
immune response may not be achieved.
Even after three doses, not all recipients of Vivotif will be fully protected against
typhoid fever. Therefore, travellers should take all necessary precautions to avoid
contact with or ingestion of potentially contaminated food or water.
Protection against typhoid fever commences approximately 7-10 days after ingesting
the third dose of vaccine.
Under conditions of repeated or continuous exposure to S. typhi protection persists
for at least 3 years.
In the case of travel from a non-endemic area to an area where typhoid fever is
endemic, an annual booster consisting of three doses is recommended.
Children under 6 years: Safety and efficacy have not been established in children
under 6 years of age.
Method of administration
The blister containing the vaccine capsules should be inspected to ensure that the
foil seal and capsules are intact.
The capsule should be taken approximately one hour before a meal with a cold or
lukewarm (temperature not to exceed body temperature, e.g. 37°C [98.6°F]) drink
on alternate days, e.g. days 1, 3 and 5. The vaccine capsule should not be chewed
and should be swallowed as soon as possible after placing in the mouth.
Vivotif must not be administered:
– To persons known to be hypersensitive to any component of the vaccine or the
enteric-coated capsule (see section 6.1).
– To persons with congenital or acquired immune deficiency (including patients
receiving immunosuppressive or antimitotic drugs).
– During an acute febrile illness or during an acute gastrointestinal illness.
Vaccination should be postponed until after recovery.
4.4 Special Warnings and Precautions for Use
4.5 Interactions with other Medicaments and other forms of Interaction
As the growth of vaccine organisms may be inhibited by sulphonamides or antibiotics,
vaccination should not commence within 3 days after completing treatment
with any antibacterial agents. Also, it is preferable that antibacterial therapy should
not commence within 3 days after the last dose of Vivotif.
If malaria prophylaxis is also required, the fixed combination of atovaquone and
proguanil can be given concomitantly with Vivotif. Doses of mefloquine and Vivotif
should be separated by at least 12 hours. For other antimalarials, there should be
an interval of at least 3 days between the last dose of Vivotif and the first dose of
Vivotif may be administered concomitantly with the live attenuated vaccines yellow
fever vaccine and oral polio vaccine.
4.6 Pregnancy and Lactation
Animal reproduction studies have not been conducted with Vivotif. It is not known
whether Vivotif can cause foetal harm when administered to pregnant women or
can affect reproduction capacity. Vivotif should be given to a pregnant woman only
if clearly needed.
There are no data regarding administration of Vivotif to nursing mothers. It is not
known if Vivotif is excreted in human milk.
4.7 Effects on Ability to Drive and Use Machines
4.8 Undesirable Effects
The following adverse reactions were reported commonly (<1/10 but >1/100)
in clinical studies:
Abdominal pain, nausea, diarrhoea, vomiting
General disorders and administration site conditions
Fever, influenza-like illness
Nervous system disorders
Skin and subcutaneous tissue disorders
The following additional adverse reactions have been reported very rarely (approximately
<1/10,000) during post-marketing surveillance:
Skin reactions such as dermatitis, exanthema, pruritus, urticaria.
Asthenia, malaise, tiredness, shivering.
Doses five-fold higher than the recommended dose do not produce vomiting, abdominal
distress or fever. However overdosing can increase the possibility of shedding
the S. typhi Ty21a organisms in the faeces.
5.1 Pharmacodynamic Properties
As a result of irreversible changes in cell wall biosynthesis, the Ty21a strain is devoid
of pathogenicity but is able to elicit an immune response against S. typhi.
Excretion of the vaccine strain after administering doses approximately 50 times greater
than those in the present vaccine was assessed by taking stool or rectal swabs
daily for 7 days following the last dose of vaccine. The rate of excretion of the vaccine
strain in the stools was low, and the vaccine strain could not be recovered from
small bowel aspirates one or more days after vaccination. Sera for determination of
antibodies to O, H and Vi antigens were obtained prior to vaccination and biweekly
for 8 weeks. Fourfold or greater responses in titre of O antibody only were observed.

There was no correlation between faecal excretion of the strain Ty21a organisms and
seroconversion with respect to titre of any of the antibodies tested.
