What is the length of deferral for symptom-free donors immunized with oral polio, measles, or mumps vaccine?

Explanation:
Live attenuated vaccines like oral polio, measles, and mumps can cause transient shedding or viremia of the vaccine strain. To protect recipients, donors who are symptom-free should wait a short period after vaccination before donating. The standard deferral is two weeks, which is long enough for the vaccine virus to clear, but not so long as to unnecessarily restrict donors. Longer deferrals or no deferral would not align with safety guidelines.
