    Snippet: Absolute reduction in IAR. As V increases from 0, a kink appears when the herd-immunity 491 threshold is attained or everyone is vaccinated under five-fold fractional-dose vaccination (i.e., 492 V = 20%). If five-fold fractional-dose vaccination at 100% coverage cannot attain the herd 493 immunity threshold (because of low fractional-dose vaccine efficacy), then a second kink 494 appears when V is large enough such that fractional-dose vaccinatio.....

If five-fold fractional-dose vaccination at 100% coverage cannot attain the herd 493 immunity threshold (because of low fractional-dose vaccine efficacy), then a second kink 494 appears when V is large enough such that fractional-dose vaccination attains herd-immunity 495 threshold due to the increase in VE(n) resulting from lower fractionation (namely n = 1/V).
