腮腺炎病毒(MUV)在人类中引起急性感染,特征是腮腺肿胀。虽然接种疫苗大大降低了MUV感染的发生率,但在高度接种疫苗的人群中,腮腺炎病毒(MUV)发生了多次大规模暴发。最常见的疫苗毒株Jeryl Lynn属于A型,不再是流行的A型。我们已经开发出两种候选疫苗,它们与美国流行的G型和中国(F型)相匹配。我们发现,与我们的两种候选疫苗相比,Jeryl Lynn疫苗对非匹配病毒产生中和抗体反应的能力显著下降。我们的数据表明,最新的疫苗可能会对流通中的MUV基因型G和F产生更好的免疫力。
Mumps virus (MuV) causes acute infection in humans with characteristic swelling of the parotid gland. While vaccination has greatly reduced the incidence of MuV infection, there have been multiple large outbreaks of mumps virus (MuV) in highly vaccinated populations. The most common vaccine strain, Jeryl Lynn, belongs to genotype A, which is no longer a circulating genotype. We have developed two vaccine candidates that match the circulating genotypes in the United States (genotype G) and China (genotype F). We found that there was a significant decrease in the ability of the Jeryl Lynn vaccine to produce neutralizing antibody responses to non-matched viruses, when compared to either of our vaccine candidates. Our data suggests that an updated vaccine may allow for better immunity against the circulating MuV genotypes G and F.
