Phase II/III of Live Attenuated Mumps (F-genotype) Vaccine (Human Diploid Cell, KMB-17) in Healthy Children Aged 5-11
October 8, 2023 updated by: Institute of Medical Biology, Chinese Academy of Medical Sciences
Mumps is an acute infectious respiratory disease caused by the mumps virus (MuV), which occurs mainly in children and adolescents.
Its main clinical symptoms were parotid gland suppurative swelling and pain with fever.
The pathological changes and harm caused by mumps was not only confined to the parotid gland, on the contrary, the social harm caused by serious complications cannot be ignored.
As mumps is a vaccine-preventable infectious disease, vaccination is a fundamental strategy for controlling mumps.
So far, there are 13 genotypes of MuV.
Based on the analysis of molecular epidemiology, the main epidemic strain of MuV in China was the F genotype.
The commonly used vaccine strains represented only a small number of known genotypes, e.g.
Jeryl-Lynn (JL) and Rubini strains, which belong to type A, Urabe strain belongs to type B, and L-Zagreb strains belongs to type D. Virus seed of Live Attenuated Mumps Vaccine (Human diploid cell) developed by the institute was SP-A strain, which was the first separation and preparation of the attenuated mumps viruses in China.
SP-A belongs to F genotype, which was the domestic epidemic genotype.
In addition, the cell substrate prepared for vaccine was human diploid cell (KMB-17 strain), which is much safer to use.
The results of phase I and II clinical trials showed that the vaccine possessed good immunogenicity and good antigenic cross-reactivity in infants (8-24 months old).

Conditions
Detailed Description
This study will recruit 12,000 subjects and be divided into two stages.
The first stage will evaluate the immunogenicity and safety of F-genotype mumps live attenuated vaccine (human diploid cells) after vaccination in 720 healthy children aged 5-11 years, and explore the detoxification in 144 subjects, who randomly selected from these 720 subjects.
The second stage will evaluate the clinical protective efficacy, immunogenicity and safety of F-genotype mumps live attenuated vaccine (human diploid cells) after vaccination in 11280 healthy children aged 5-11 years.
