KRT88P and infection: The European Conference on Infections in Leukaemia recommend that patients infected with HBV before HSCT (HBsAg-negative and anti-HBc-positive) should be assessed regularly for anti-HBs titers and vaccinated if they have unprotective titers; if anti-HBs titers are <10 mIU/mL at 1–2 months after initial three vaccine doses, an additional series of three doses should be considered [14].
