dose of 0.5 ml contains
-Measles
virus, Edmonston – Zagreb, HDC
not less than 1000 CCID50
-Mumps
virus, L-Zagreb, CF not
less than 5000 CCID50
-Rubella
virus, RA27/3, HDC
not

-------------------------------------------------------------------------------------------------------------------
Properties
The
vaccine is prepared by propagation of live
attenuated viruses; measles (Edmonston –
Zagreb strain) and rubella virus (RA27/3 strain)
grown in human diploid cells (HDC) and mumps
(L-Zagreb strain) grown in cell cultures of
chick fibroblasts (CF) derived from chick embryo
of specified pathogen free flocks (SPF).
Lyophilized
vaccine is dissolved with water for injection
provided. Due to small differences in pH values,
the dissolved vaccine is a clear yellow to clear
pink.
The
production and control of measles, mumps and
rubella vaccine (live) complies to the
respective monograph of current European
Pharmacopoeia.
-------------------------------------------------------------------------------------------------------------------
Indications
The
vaccine is indicated for active immunization
against measles, mumps and rubella the vaccine
should be used at an age when passive protection
through the mothers antibodies is lost in
children, the immunization against measles,
mumps and rubella should be obligatory,
indicated in children at twelve months of age or
older. Immunization is also indicated in
children up to 18 months of age or older, if
they have not received immunization against
these diseases. The second dose of MMR vaccine
should be routinely administered at the age of 6
to 7 years.
Persons
with history of measles, mumps and rubella are
also subject to immunization.
-------------------------------------------------------------------------------------------------------------------
Contraindications
-pregnancy;
-acute
infectious diseases;
-febrile
state;
-immune
deficiency; primary (congenital) and secondary
(caused by a malignant disease or drug use such
as antimetabolites, corticosteroids, alkylating
agents and radiations);
-with
in three moths following blood plasma
transfusion, or immunoglobulin therapy (or after
even longer period, if greater doses have been
used), i .e.
Within six months after
exsanguinotransfusion;
-hypersensitivity
to vaccine ingredients;
Although
grown in primary culture of chick fibroblasts,
there is no evidence of allergic reactions in
immunized persons allergic to chicken or chicken
feathers. Diarrhoea or benign acute diseases of
the upper respiratory tract, as well as
seropositivity to HIV are not contraindicated to
vaccination against measles, mumps and rubella.
-------------------------------------------------------------------------------------------------------------------
Precautions
-a
through case history should precede immunization
-in
case the vaccinations have not been administered
at the same time, a period of at least one month
should expire between two immunizations with
live virus vaccines
-tuberculin
skin tests (Mantoux test) should be done before,
or least 2 months after administration of
measles, mumps and rubella vaccine, because of a
possible occurrence of a transient inhibition of
cellular immunity
-children
prone to infectious disease should be immunized,
like in asthma, cystic fibrosis, celiac disease,
chronic lung disease congenital heart diseases,
Down’s syndrome, stable neurological
conditions, malnutrition, as well as premature
infants regardless of the degree of prematurity
-Antishock
therapy should be used in case possible
anaphylactic reaction!
-------------------------------------------------------------------------------------------------------------------
Pregnancy
an lactation
The
vaccine must not be used in pregnancy.
Conception should be avoided for two months
after vaccination, because of the presence of
the virus in the body. As the excretion of the
active substances (viruses) in the milk has been
described in the literature, the vaccination
during lactation should be avoided.
-------------------------------------------------------------------------------------------------------------------
Adverse
effects
Local
Transient
pain and irritation (edema, indurations and
erythema) at the site of injection
General
The
most frequent reaction to vaccination with live
attenuated morbilla virus are increased body
temperature following approximately one week
after vaccination and skin rash.. increased body
temperature, parotid swelling and skin rash
appear in rear cases as reactions to the mumps
component adds side effects to rubella
components, arthralgia and arthritis appear to
be associated with the age of the immunized
persons, that is they are reported in up to 2%
of girls 6 to 12 and 13 to 16 years of age, in
relation to 25% of girls and women 20 to 24
years of age.
There
are data available in relation to the incidents
of side effects upon the administration of the
second dose of vaccine; a higher risk of side
effects is recorded in the age group of 11 to 12
years than in the age group 6 to 7 years of age.
-------------------------------------------------------------------------------------------------------------------
Dosage
and administration
The
lyophilized vaccine should be diluted
immediately prior to use!
0.5
ml water for injection should be taken as
diluents for one dose of vaccine.
2.5
ml water for injection should be taken as
diluents for five doses of vaccine.
A
certain amount of diluents should be withdrawn
via a sterile needle into the sterile syringe.
To obtain a prescribed suspension the diluents
should be injected into a vial of lyophilized
vaccine and agitated gently in order to avoid
the formation of foam. In multiple dose vial, a
new sterile needle and the syringe should be
used for each (0.5 ml) per dose
The
vaccine should be heated to body temperature
prior to vaccination (by holding in closed
fist); the vaccine should not come into contact
with disinfectants.
The
usual 0.5 ml dose should be injected
subcutaneously into the upper arm in the region
of the deltoid muscle.
From
the microbiological point of view the
reconstituted vaccine should be used as soon as
possible. Should the vaccine not be used
immediately the person administering the vaccine
should be responsible for its proper storage and
labeling. Reconstituted vaccine should be kept
at temperatures between 2 and 8o
C and used within 8 hours, expect instances
where the vaccine has been opened and dissolved
in controlled and validated aseptic conditions.
-------------------------------------------------------------------------------------------------------------------
Drug
interactions
Vaccine
against measles, mumps and rubella may be used
simultaneously with other live virus vaccines,
(vaccine against polio, hepatitis B and yellow
fever) and bacterial vaccines in vaccines
against diphtheria, tetanus and Pertussis).
Other commercially individual vaccines
should not be mixed in the same syringe in the
measles, mumps and rubella vaccine (expanded
program of immunization of the world health
organization)
-------------------------------------------------------------------------------------------------------------------
Storage
Store
the vaccine at 2 to 8o
C protected from light.
-------------------------------------------------------------------------------------------------------------------
Shelf-life
The
expiry dated of the vaccine is indicated on the
package.
-------------------------------------------------------------------------------------------------------------------
Presentation
-50
vials with as 5 doses of vaccine in a box and 50
ampoules with 2.5 of water for injection in a
box.
