Why doesn’t Finland employ deferral periods after coronavirus vaccination?

Deferral periods are not required, as coronavirus vaccines do not pose a risk to the safety of blood products. Some countries employ deferral periods because if the donor has a reaction to the vaccine, the blood products already donated must be removed from storage, as it is not certain whether the symptoms/fever are due to an illness. After comparing this wastage with the one that would result if nobody could donate blood for a few days after vaccination, we concluded that routine deferral periods would cause more wastage.
