  "Vaccins bivalents contre la rubéole et la cytomégalie"  <EMI ID=1.1> 

  
La présente invention concerne des compositions vaccinales bivalentes contre la rubéole et la maladie des inclusions cyromégaliques ou cytomégalie.

  
On sait que le virus de la rubéole peut traverser le placenta

  
 <EMI ID=2.1> 

  
le nouveau-né.

  
L'existence d'anticorps maternels circulants contre le virus de la rubéole peut prévenir cette grave menace et divers vaccins ont été développés depuis plusieurs années, tant sous forme de vaccins monovalents que sous forme de combinaison à d'autres vaccins tels les vaccins contre la rougeole ou contre les oreillons.

  
Comme exemples de vaccins atténués contre la rubéole on peut

  
 <EMI ID=3.1> 

  
souche HPV 77 DE5 ou la souche CENDEHILL&#65533;.

  
Cependant le virus de la rubéole n'est pas le seul virus capable de provoquer des ravages chez le foetus. En effet, le virus de la maladie des inclusions cytomégaliques -également

  
 <EMI ID=4.1> 

  
cas d'arriération mentale et de microcéphalie d'origine virale chez le nouveau-né; on escime que parmi les nouveau-nés excrétant le virus (de 1 à 4 % de la totalité des nouveau-nés), 5 à 15 % présentent des caractéristiques d'arriération mentale et que

  
30 à 45 % des femmes en âge d'être mères ne possèdent pas

  
 <EMI ID=5.1> 

  
C'est pourquoi on étudie actuellement dans plusieurs pays l'innocuité et l'efficacité de vaccins contre la cytomégalie. Des

  
 <EMI ID=6.1> 

  
125 (Jupt M et coll Infection _3 : 111-4 1975) et une ?ouche vacci-

  
 <EMI ID=7.1> 

  
1-5,1974). Comme chacun des vaccins contre la rubéole et contre la cytomégalie vise le même but -la protection du foetus- et s'administre par la même voie, il est intéressant de pouvoir administrer simultanément les deux vaccins sous la forme d'un vaccin combiné et plus particulièrement sous la forme d'un vaccin combiné vivant. De plus, l'utilisation de vaccins combinés exige un personnel médical moins important et des injections moins fréquentes que ne l'exige l'utilisation de vaccins monovalents. Certains'travaux in vitro

  
ont montré qu'il existe des possibilités d'interférence entre le

  
CMV et des virus comme des myxovirus, des arbovirus, des picorna-

  
 <EMI ID=8.1>  

  
 <EMI ID=9.1> 

  
démontré que le virus de la rubéole provoque -in vitro- des interférences avec des virus hétérologues tels les picornavirus,

  
les myxovirus et les arbovirus (Parkman P.D. et coll., J. Immunology

  
 <EMI ID=10.1> 

  
 <EMI ID=11.1> 

  
de procéder à des essais préliminaires établissant le facteur d'interférence éventuel pour la combinaison envisagée.

  
Nous avons trouvé que dans le cas d'un vaccin vivant contre

  
la rubéole combiné à un vaccin vivant contre la cytomégalie, l'administration simultanée des deux virus n'affecte pas la réponse immunitaire à chaque composant vaccinal.

  
Dès lors, l'invention consiste en un vaccin combiné vivant contre la rubéole et la cvtomégalie contenant au moins les quantités de virus atténués de la rubéole et de CMV correspondant à la quantité immunisante de chacun desdits virus considérés séparément, la quantité de virus de la rubéole étant de préférence d'au moins

  
 <EMI ID=12.1> 

  
Pour réaliser la présente invention, les virus atténués sont

  
cultivés séparément suivant les techniques habituelles et mélangés dans les proportions adéquates et le vaccin bivalent obtenu est de préférence lyophilisé après adjonction d'une composition stabilisatrice, comme il est bien connu dans la technique. Comme compositions stabilisatrices, on peut indiquer entr'autres celles qui sont à base d'albumine sérique humaine ou de polyvinylpyrroli done.

  
Etant donné que la stabilité in vitro du CMV est relativement moins bonne que celle du virus de la rubéole, les conditions de lyophilisation du vaccin bivalent sont celles requises pour la lyophilisation du CMV.

  
Comme indiqué plus haut, la souche de virus de la rubéole peut être une souche vaccinale quelconque connue de l'homme de l'art, par exemple la souche atténuée CENDEHILL&#65533; cultivée sur cultures primaires de cellules de rein de lapin et la souche de CMV peut être une souche vaccinale quelconque connue de l'homme de l'art, par exemple la souche atténuée TOWNE 125 cultivée sur la lignée de cellules diploïdes humaines Wi-38.

  "Bivalent vaccines against rubella and cytomegaly" <EMI ID = 1.1>

  
The present invention relates to bivalent vaccine compositions against rubella and cyomegalic inclusion disease or cytomegaly.

  
Rubella virus is known to cross the placenta

  
 <EMI ID = 2.1>

  
the newborn.

  
The existence of circulating maternal antibodies against the rubella virus can prevent this serious threat and various vaccines have been developed for several years, both as monovalent vaccines and as a combination with other vaccines such as vaccines against rubella. measles or mumps.

  
Examples of attenuated rubella vaccines can be

  
 <EMI ID = 3.1>

  
strain HPV 77 DE5 or strain CENDEHILL &#65533;.

  
However, the rubella virus is not the only virus capable of wreaking havoc on the fetus. This is because the cytomegalic inclusion disease virus - also

  
 <EMI ID = 4.1>

  
cases of mental retardation and microcephaly of viral origin in newborns; it is estimated that among newborns shedding the virus (1 to 4% of all newborns), 5 to 15% have features of mental retardation and that

  
30 to 45% of women of childbearing age do not have

  
 <EMI ID = 5.1>

  
Therefore, the safety and efficacy of cytomegaly vaccines are currently being studied in several countries. Of

  
 <EMI ID = 6.1>

  
125 (Jupt M et al Infection 3: 111-4 1975) and a vaccine strain

  
 <EMI ID = 7.1>

  
1-5,1974). As each of the vaccines against rubella and against cytomegaly has the same goal - the protection of the fetus - and is administered by the same route, it is advantageous to be able to administer the two vaccines simultaneously in the form of a combined vaccine and more particularly in the form of a combined live vaccine. In addition, the use of combination vaccines requires fewer medical personnel and less frequent injections than required by the use of monovalent vaccines. Some in vitro work

  
have shown that there are possibilities of interference between the

  
CMV and viruses such as myxoviruses, arboviruses, picorna-

  
 <EMI ID = 8.1>

  
 <EMI ID = 9.1>

  
demonstrated that the rubella virus causes -in vitro- interference with heterologous viruses such as picornaviruses,

  
myxoviruses and arboviruses (Parkman P.D. et al., J. Immunology

  
 <EMI ID = 10.1>

  
 <EMI ID = 11.1>

  
to carry out preliminary tests establishing the possible interference factor for the envisaged combination.

  
We have found that in the case of a live vaccine against

  
rubella combined with a live cytomegaly vaccine, simultaneous administration of the two viruses does not affect the immune response to each vaccine component.

  
Therefore, the invention consists of a combined live vaccine against rubella and cvtomegaly containing at least the amounts of attenuated rubella virus and CMV corresponding to the immunizing amount of each of said viruses considered separately, the amount of virus of the rubella is preferably at least

  
 <EMI ID = 12.1>

  
To carry out the present invention, the attenuated viruses are

  
cultured separately according to the usual techniques and mixed in the appropriate proportions and the bivalent vaccine obtained is preferably lyophilized after addition of a stabilizing composition, as is well known in the art. As stabilizing compositions, mention may be made, among others, of those which are based on human serum albumin or on polyvinylpyrroli done.

  
Since the in vitro stability of CMV is relatively less good than that of rubella virus, the lyophilization conditions of the bivalent vaccine are those required for the lyophilization of CMV.

  
As indicated above, the rubella virus strain can be any vaccine strain known to those skilled in the art, for example the attenuated strain CENDEHILL &#65533; cultured on primary cultures of rabbit kidney cells and the CMV strain can be any vaccine strain known to those skilled in the art, for example the attenuated strain TOWNE 125 cultured on the human diploid cell line Wi-38.

  
When the bivalent vaccine which is the subject of the present invention is presented in lyophilized form, it is reconstituted at the point of use by adding water or any other diluent.

  
 <EMI ID = 13.1>

  
 <EMI ID = 14.1>

  
The bivalent vaccine thus prepared is administered intramuscularly or subcutaneously.

  
The invention is illustrated;: but not limited by the examples

  
 <EMI ID = 15.1>

  
EXAMPLE 1

  
 <EMI ID = 16.1>

  
 <EMI ID = 17.1>

  
add the same volume of an aqueous solution of sucrose

  
 <EMI ID = 18.1>

  
sodium dibasic (0.0072 M), potassium glutamate (0.0049 M) and sodium edetate (0.2%) with the addition of one percent human serum albumin.

  
 <EMI ID = 19.1>

  
 <EMI ID = 20.1>

  
aqueous solution of sucrose (200 g / l.) and potassium glutamate (30 g / l.).

  
The two preparations are mixed and the mixture is distributed in glass vials at a rate of one milliliter of mixture per vial to constitute unit doses which can be administered by the intramuscular or subcutaneous route.

  
A clinical study carried out on 13 adults sensitive to each of the two viruses demonstrated the appearance of antibodies against the rubella virus - demonstrated by the haemagglutinatior inhibition test

  
 <EMI ID = 21.1>

  
6 to 8 weeks after administration of the bivalent vaccine.

EXAMPLE 2

  
 <EMI ID = 22.1>

  
 <EMI ID = 23.1>

  
add the same volume of an aqueous solution of sucrose
(0.218 M), monobasic potassium phosphate (0.0038 M), dibasic sodium phosphate (0.0072 M), potassium glutamate (0.0049 M) and sodium edetate (0.2%) plus a percent human serum albumin.

  
At 90 ml. supernatant from a primary culture of

  
 <EMI ID = 24.1>

  
aqueous solution of sucrose (200 g / l.) and glutamate

  
n <EMI ID = 25.1>

  
The two preparations are mixed and the mixture is distributed in glass vials at the rate of one milliliter per vial and lyophilized.

  
After lyophilization and hermetic stoppering, each vial contains a unit dose of bivalent vaccine with a titre of

  
 <EMI ID = 26.1>

  
rubella virus,

  
The vaccine is administered intramuscularly or subcutaneously.
