Problems solved by technology

However, as the Jeryl-Lynn strain is further passaged, there is no guarantee that this balance between the two variants will be maintained
It is also difficult to estimate the proportion of these two variants in any batch of vaccines

Embodiment Construction

[0037] 1) Preliminary sequencing of the SH gene

[0038] at 25cm 2 On the overgrown monolayer Vero cells in the culture flask, use dMEM Biorich medium (50 / 50 V / V) plus 0.5% fetal bovine serum, inoculate about 3.0log TCID 50 MumpsVax virus was commercially available for passaging. Incubate at 34°C for 7 days, then harvest infected cells, extract RNA by the method of Ferré and Garduno (Nucleic Acids Research 1989, 17; 2141), place in 100mcl water, and treat with diethylpyrocarbonate at 100°C 5 minutes. Take 5 mcl of such extracts and add the following reagents for reverse transcription: 40 units of RNAsin (Boehringer Mannheim, Germany), 4 mcl of 5X concentrated reverse transcriptase buffer (Bethesda Besearch Labs), 2 mcl of a mixture of four deoxynucleoside triphosphates The concentration was 10 mM, 10 pmole NH2 oligonucleotide primer, 1 mcl Moloney murine leukemia virus (MMLV) reverse transcriptase (Bethesda Research Labs, 200 units per mcl), and water was added to make th...

Abstract

A new mumps vaccine is presented, comprising a homogeneous pure isolate derived from the Jeryl-Lynn strain of mumps virus. In a preferred embodiment of the invention the vaccine produces higher seroconversion and antibody titres than known commercial vaccines.

Description

[0001] related application [0002] This application is a divisional application of Chinese application 200410003915.4. The filing date of the parent application is November 15, 1994. This divisional application adopts the same invention title as the parent application. technical field [0003] The present invention relates to a mumps vaccine comprising a homogeneous purified isolate derived from the Jeryl-Lynn strain of mumps virus. Background technique [0004] Mumps is basically a disease of children, usually with mild clinical symptoms. However, the clinical consequences of mumps infection are severe in some cases. For example, mumps is the most common cause of meningoencephalitis in children under 15 years of age and a cause of permanent sensorineural deafness in children in the United Kingdom. Although 30-40% of natural mumps infections are asymptomatic, the salivary glands are involved and, in the adult population, mumps causes first trimester abortion in addition t...
