“…In this study, we used endpoint dilution RT-QuIC on the brain homogenates from wild-type mice with mouse-adopted bovine spongiform encephalopathy (mBSE) at defined intervals during the incubation period and evaluated the temporal relationship among prion seeding dose, levels of proteinase-resistant PrPSc (PrPres), and infectious titer. We found that the infectious titer reached a plateau by 100 days postinfection, whereas seeding dose and PrPres levels were continuously elevated. …”

“…Among subjects who received two doses of measles vaccine, the neutralizing antibody titer tended to decline over time. In addition, data collected from a neutralization assay performed on 110 healthy vaccinated subjects suggested an inverse correlation between neutralizing antibody titers and the time elapsed between the two vaccinations, with a significant decline in the neutralizing titer when the interval between the two doses was ≥11 years. …”
