Precautions
It is very important that your doctor check you or your child's progress at regular visits to make sure that this vaccine is working properly. Blood tests may be needed to check for unwanted effects.
This medicine is made from donated human blood. There is a very small risk for the transmission of viral diseases. Human donors and donated blood are both tested for viruses to keep the transmission risk low. Talk with your doctor about this risk if you are concerned.
Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal or vitamin supplements.
