    Good evening.
    I read with much interested this article.
    Investigation is a fundamental tool the get us all out of this Pandemic.
    However, I find hard to get the timetable in Mab's stability.
    "The levels of NAbs remained stable without decaying, reaching their peak at 252 weeks after vaccination"
    252 weeks is over 4 and an half years long.
    Are the mice being kept for so long?
    Is it a prediction value?
